Some switches, such as the Catalyst 4000/5000/6000, can shut down the port if software processes inside the switch detect an error. 0000002111 00000 n Also, MLS must be enabled in order for a switch to be an MLS-SE. (This function is explained in detail in the upcoming section Site-external route server. Legends of Tomorrow is an American television series, developed by Greg Berlanti, Marc Guggenheim, Phil Klemmer, and Andrew Kreisberg, based on several characters from DC Comics.The series premiered in the United States on January 21, 2016, for The CW television network, and it finished its first season on May 19, 2016. A Graceful Restart Helper device will delete all stale routes once this timer is expired by assuming the restarting device failed to restart its routing protocol. VXLAN BGP EVPN uses the Distributed Anycast Gateway (DAG) as a first-hop gateway, whereas the legacy sites likely use a First-Hop Redundancy Protocol (FHRP) such as Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), or Gateway Load-Balancing Protocol (GLBP). Network Access is defined on a per of the network. Thanks to the table map on OSPF or EIGRP, this potential loop route does not show up in the routing table. Note:You can disable the priority queue with the mls qos srr-queue input priority-queue 2 bandwidth 0 command. Action: Permit or deny action was introduced in APIC Release 2.3(1). DSR Virtual IP address must be part of a base EPG that is not uSeg EPG. Configure the neighbor with the EVPN address family (L2VPN EVPN) for the site-external overlay control plane facing the BGW. To access Cisco Feature Even then the configuration is per port. border guard, bouncer, ticket checker), or with a device such as a turnstile.There may be fences to avoid circumventing this access control. Hence, if a routing protocol, or static route, does not have the route for the destination, a packet will not be forwarded even if a packet is classified into the correct L3Out EPG with the appropriate contract thanks to the External Subnets for the External EPG scope. Except for routers for which IP MLS is automatically enabled (like the Catalyst 6xxx MSFC), this is a required configuration step. Another one is the Layer 3 Out (L3Out, or external routed network in Cisco APIC GUI prior to the APIC Release 4.2), which is to provide Layer 3 (L3) connectivity between servers connected to ACI and other network domains outside of the ACI fabric through routing protocol or static route. BGP IPv4/v6 Address Family (AF) is deployed on all leaf switches (both border and nonborder leaf switches) in all user VRFs. The bandwidth is guaranteed at this level but not limited to it. and High Availability are supported. This feature is to advertise only a summarized prefix for BD subnets and/or Transit Routes from ACI OSPF L3Out to outside. Now do the timing test with Portfast enabled. The final result gives a time of 2 seconds (0528 to 0530). Only IP addresses in VRF default that are extended with the matching tag of the route map are redistributed. Ports can form an EtherChannel when they are in different channel modes as long as the modes are compatible: A port in desirable mode can form an EtherChannel successfully with another port that is in desirable or auto mode. 0000012713 00000 n messages. IP MLS is now a standard feature in IOS 12.0 and later router software. And also, this prevention mechanism will not be activated if either the bridge domain subnets or the routes received from the L3Out connection doesnt cover 10.0.0.99. This solution is discussed in the next section. This step shows that it is possible for a Link Partner to detect the speed at which the other Link Partner operates, even though the other Link Partner is not configured for auto-negotiation. If the packet is an IP packet and routing is performed by the Cisco ACI leaf, the Cisco ACI leaf learns IP A tied to MAC A based on the IP header. to 2. Note: As of Cisco NX-OS 7.0(3)I7(1) for the Cisco Nexus 9000 Series EX- and FX-platform switches, local endpoint connectivity is not supported on an EVPN Multi-Site BGW. Notice that the ports on SwitchB are now disabled and have a status of errdisable. Contact the Cisco Technical Support Centre for the specific list of features that are EVPN Multi-Site architecture can also be used for DCI scenarios (Figure 3). L3Out static-route configuration in GUI (APIC Release 3.2), L3Out static route in GUI (APIC Release 4.1). Future versions of the operating system can periodically check if errdisable ports must be enabled. This is the most basic configuration, as explained above. This option was introduced in APIC Release 2.2(2). Policy Control Enforcement Direction and packet flow. After a switchover, the original router MAC address is still used. The ACI fabric will flood the ARP request within the BD when the ARP flooding option is enabled. A bounce entry is basically a remote endpoint created by COOP communication instead of data-plane learning. If there are other OSPF L3Outs on the same border leaf in the same VRF, the summarized route will be advertised from all of them except the source L3Out. The CPU on the Cisco StackWise Virtual active switch runs the IPv4 routing protocols and performs any required software forwarding. When the BGW and spine are combined, the exit points of the fabric and the spine are on the same set of network nodes. From Cisco IOS XE version 16.9.1 release onwards, the Catalyst 3650/3850 and Catalyst 9000 series switch platforms support the Cisco Smart Licensing method as the only licensing method. The EIGRP Interface Policy itself is located under Tenant > Policies > EIGRP > EIGRP Interface. The IP routing is enabled on the MLS-RP (it is on by default): if the command no ip routing appears in the global configuration of a show run, it has been turned off, and IP MLS does not function. This policy is used under VRF but the OSPF Timer Policy itself is located under Tenant > Policies > OSPF > OSPF Timers. Now disable the ports on SwitchA until both switches have been configured for EtherChannel so that spanning tree does not generate errors and shut down the ports. The Protocol independent multicast designated router (PIM DR) configuration should be fine-tuned to selectively build a multicast To enable this option, Remove all private AS needs to be enabled. This approach requires the BGW to locally originate the default route and inject it into the BGP EVPN control plane facing the site-internal VTEPs. The DSR configuration is downloaded to all the leaf switches on which the EPG with an L4-L7 virtual IP address is deployed, or on which an EPG with a contract with the EPG with the L4-L7 virtual IP address is deployed, regardless of the contract direction. Host Tracking is always enabled and will send three ARP requests to the IP address in order to make sure that the IP address is still responsive. Class-A matches the IP phone traffic and Class-B matches the database application traffic from the PC. Unlike the Route Profile on L3Out EPG, there is no direction in the BD. Hence, the subnet advertisement configuration in one L3Out will be applied to all BGP peers in the same L3Out. With APIC Release 3.0 or earlier, the Endpoint Dataplane Learning option, under the bridge domain, must be disabled when that bridge domain is connected to a service graph device using the PBR feature. BFD This feature was introduced in APIC Release 1.2(2). In that case, the contract for this packet flow always was applied on the border leaf (egress), where TCAM capacity for contracts could be a bottleneck. Figure 3 shows an example of Command-Line Interface (CLI) output for a local and a remote endpoint on a leaf switch. As Figure 98 shows, Type Match Routing Policy Only (scenario 3) completely ignores the L3Out subnets with an Export Route Control Subnet scope. A flow diagram for basic IP MLS troubleshooting is included and discussed. The only exception is that the native VLAN on For migration and integration purposes, existing non-VXLAN BGP EVPN sites (legacy sites) require connectivity with VXLAN BGP EVPN sites. Saves the running-configuration which resides in the system RAM and updates the ROMmon variables. However, the Import Route Control Subnet scope is not used as often because the default import behavior where ACI learns all external routes suffices in most situations. Define a prefix list that matches the default route. In this scenario LEAF1 should never learn IP 192.168.1.1 from the actual host device. How to Reduce Startup Delay on the Catalyst 4000/5000/6000 Switch, How to Reduce Startup Delay on the Catalyst 2900XL/3500XL Switch, How to Reduce Startup Delay on the Catalyst 1900/2800 Switch. Once a channel is formed, whatever is changed on one port is also changed for the other ports in the channel. One can have multiple switches and routers in the network, and even multiple switches along the flow path, but the path between the two end devices for which one desires an MLS shortcut must include a single MLS-RP in that VLAN for that path. In addition to choosing the underlay routing protocols, you must separate the site-internal and site-external routing domains. The route map is used to select all IP addresses that are attached to an interface and that carry the tag extension. On the ingress queues, SRR sends packets to the stack ring. The default-export Route Profile will also be applied to BD subnets with an Advertised Externally scope in a BD that has association to this L3Out. mls rp management-interface Do this for only one interface on the MLS-RP. It is located under Tenant > Networking > External Routed Networks > L3Out > Networks > L3Out EPG > Subnets. Default Route Leak Policy was introduced in APIC Release 1.1(1) and can be created under an L3Out through either of the following means: Create Default Route Leak Policy from a dropdown menu at the top right in L3Out, Create Default Route Leak Policy from the right-click menu in L3Out itself. These overlay networks use the closest to the source and closest to the destination approach and dynamically build tunnels from point to point wherever needed. After the traffic is classified and marked with QoS labels, you can assign the traffic into two different queues based on the QoS labels. The campus local area network (LAN) is the network that supports devices people use within a location to connect to information. When using the second option, please be aware of the following behavior: It is applied to routes from routing protocols (the green arrow in Figure 109 and Figure 110). To allow the underlay and overlay control planes to converge before data traffic is forwarded by the BGW, you can configure a restore delay for the virtual IP address to delay its advertisement to the underlay network control plane. First we set the channel mode back to auto in order to tear down the current channel, then we set the channel manually to on. Note: The SVI identifier must match the identifier that was chosen earlier. Instead, this section covers the root component of L3Out. At least one L3Out EPG is also required to deploy a routing protocol and related interface parameters on leaf switches even though the L3Out EPG itself is a security construct like the EPGs, and is not a routing protocol configuration. If you want to reduce the potential downtime to last less than the hold time you can delete the Rogue endpoints manually even before the hold interval expires by using the option Clear Rogue Endpoints at Fabric > Inventory > Pod_number > Leaf_name (Figure 63). OSPF Area Type ACI supports all three OSPF area types: Regular, NSSA, and Stub area. This ID is defined as part of the BGW configuration (evpn multisite border-gateway ). It is important to ensure that both Transit Routing for BGP and BD subnet advertisement are configured with the correct subnets to prevent unintended advertisement. If the traffic exceeds 25Mbps, remark the DSCP values using the policed-DSCP map table. In this case, queue 1 and queue 2 are serviced at the rate of 45% each. The BGW provides the capability to enforce these traffic classes individually through a rate limiter. A workstation connected to a switch usually does not cause spanning tree loops, usually does not need EtherChannel, and usually does not need to negotiate a trunking method. By default it spends approximately 15 seconds listening and 15 seconds learning. control communication between stack members is carried over the reserved VLAN ID 4094 from the global range. Then a default route is generated, and only the default route will be advertised. Now we shut down port 2/1 on SwitchB. Microsoft is quietly building a mobile Xbox store that will rely on Activision and King games. Additionally, LEAF1 will try to learn the source IP address 10.0.0.99 as a remote endpoint because of Cisco ACI endpoint data-plane learning. These protocols Get the latest news and analysis in the stock market today, including national and world stock market news, business news, financial news and more This document focuses mainly on two main models for the underlay. The site-external interfaces offer a configuration similar to that for the site-internal interfaces to understand their locations and the need for tracking (evpn multisite dci-tracking). Using VRF tags in Transit Routing to prevent loops. If the packet is an ARP request, the Cisco ACI leaf learns IP A tied to MAC A based on the ARP header. Typically, users do not need to change the mode of this configuration since the default Ingress is the mode for saving TCAM resources. When both Import Route Control Subnet and Aggregate Import are enabled for 0.0.0.0/0, ACI creates an IP prefix-list with 0.0.0.0/0 le 32, which matches any subnets. Note for the option at VRF: The above remote MAC learning behaviors apply to second-generation leaf switches. Hence, in this particular example, all routes from any VRFs are subject to be leaked (imported via MP-BGP) to VRF 2 due to Aggregate Shared Routes in L3Out 3. After the traffic is classified and marked with QoS labels, you can assign the traffic into two different queues based on the QoS labels. The "a-" prefix on the Duplex and Speed status fields does not always mean the current behavior was negotiated. A broadcast sent from SwitchB to SwitchA on port 2/1 is sent back to SwitchB on ports 2/2, 2/3 and 2/4 because SwitchA treats these ports as independent ports. This is to ensure the prefix does not get dampened indefinitely. the changes will no longer be part of the startup configuration when the switch reloads. Why you need to disable endpoint data-plane learning (server1 is active). Upgrade the MLS-RP and SE to meet minimum software and hardware requirements. When the IP Data-plane Learning option is disabled, endpoint learning behavior on an ACI leaf changes as follows: Local MACs and remote MACs are learned via the data plane (no change with this option). The introduction of the peer-type fabric-external function helps ensure that the advertised VTEP IP information is properly rewritten (virtual IP address) and that the RMAC address present in EVPN Route Type 2 and Route Type 5 matches the virtual MAC address of the BGW. The shared border acts as a common external connectivity point for multiple VXLAN BGP EVPN fabrics that are interconnected with EVPN Multi-Site architecture. This is because of how the hardware is programmed when using both the global Enforce Subnet Check and (no) IP Data-plane learning. This option is located at System > System Settings > Endpoint Controls > Rogue EP Control (Figure 62). set port channel auto - to reset the ports to their default mode of auto. Track Policy This configuration defines a group of IP addresses whose reachability is used by ACI to decide whether this next-hop entry for the static route should be kept in the routing table or not, instead of directly monitoring the next-hop IP. With EVPN Multi-Site architecture and the BGWs, you can compartmentalize functional building blocks within the data center. Local IPs are not learned via the data plane. An endpoint moves to different interface. 0000015481 00000 n Example diagram of a shared L3Out configuration. Assuming a fabric with two spine switches and four BGWs, a full mesh of links is established between the neighboring spine and BGW interfaces. leaf1# show sprom backplane | grep 'MAC Address'. In virtual switch mode, the requirements to support non-stop forwarding (NSF) match those in the standalone redundant mode The configured rate-limiting level represents the amount of BUM traffic allowed from each interface that faces the site-external network. You can configure to set any default CoS or DSCP value to this class-default traffic. On the other hand, the benefit of disabling ARP flooding is to be able to optimize traffic flow by sending the ARP request directly to the location of the target IP, assuming no endpoint moves without notifying its movement via GARP and such. A StackWise Virtual link transports control messages between two switches. It discusses deployment options using the data-plane learning options listed in Table 1. When choosing between shared and dedicated external connectivity interfaces, note that you also need to consider your needs for bandwidth and additional resiliency. The steps are queueing, dropping and scheduling. The running of the STP causes all ports that are included in the spanning tree process to become active much slower than they otherwise would, as it detects and blocks loops. The following additional options are available, as in a standalone NX-OS: no-prepend This option prevents ACI from prepending the local AS in the AS_PATH of routes learned from this neighbor. At this time, in Figure 51, an endpoint with IP1 is sending traffic to another endpoint with IP2 on the border leaf in the same Pod1. In other words, the port will take at least 30 seconds to move to the forwarding state whenever it initializes. In shared mode, the queues share the bandwidth among them according to the configured weights. Duplex Mismatch: If the switch port receives a lot of late collisions, this usually indicates a duplex mismatch problem. You can research known bugs if you read the release notes for the version of code you use or use Cisco Bug ToolKit. Mark DSCP value of the softphone application packets from the PC which is connected the IP phone. From an intersite underlay, eBGP can be replaced with any routing protocol, as long as a clean separation exists between the site-internal and site-external routing domains. All four queues participate in the SRR unless the priority queue is enabled, in which case the first bandwidth weight is ignored and is not used in the ratio calculation. While the network design in the underlying topology was predominantly Layer 3 and an efficient hierarchy was present, with the introduction of the overlay network this hierarchy became hidden. It does not mean that all of the other L3Outs have to be deployed at the same time. But another hub or switch can cause a loop, and we want to always go through the normal listening and learning stages when we connect to these types of devices. With the default configuration parameters above, Endpoint Move Dampening disables endpoint learning on the bridge domain for 300 seconds if the number of endpoint moves is more than 256 times per second. If you set the speed and duplex manually on our side, it requires that you set the speed and duplex on the other side, as well. The only devices that generate traffic are the switches themselves. A packet with IP 10.10.0.1 will be classified into L3Out EPG B instead of L3Out EPG A. In order to keep connections quick and reliable, networks must be able to rapidly adjust to changes and failures and find the best path, all while they remain as invisible as possible to end users. One such deployment case is described in the Shared border section of this document, and one is described in the Legacy site integration section. Virtual standby switch. Hence, external devices need to peer with the ACI BGP AS (as shown in Figure 32) unless ACI uses a local-as configuration in the BGP Peer Connectivity Profile to make its BGP AS look like something else to the peer. Refer to the section Disable Remote EP Learn option (on border leaf) for details. L3Out subnet shared service scope in the GUI (APIC Release 3.2). The port trust configuration options are: Example 1: If the port is an access port or Layer 3 port, you need to configure the mls qos trust dscp command. An example of the corner case is mentioned in Disable Remote EP Learn (on border leaf) section with CSCva56754. session. Therefore, every BGW has an active role in BUM forwarding. Please remember that Export/Import Route Control Subnet scope only supports 0.0.0.0/0 to use Aggregate Export/Import option. BGW back-to-back model (BUM traffic acceptable). For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. 10.0.0.0/8 with a Shared Route Control Subnet scope, 10.1.0.0/16 and 10.2.0.0/16 with a Shared Security Import Subnet scope (and an External Subnets for the External EPG scope). Configure the eBGP neighbor by using BGP peer templates and activating the EVPN address family (address family L2VPN EVPN). Be sure and specify the module number (2 in this case) so that the command shows you the channel mode even if there is no channel formed. Routing protocol This is the routing protocol that is deployed with the L3Out on the node and interface specified by the Logical Node/Interface Profile. This output is for port FastEthernet 0/26, which is port "A" on this switch. The site-external underlay network can be deployed with various routing protocols, but eBGP is typically used to provide reachability between the BGWs of multiple sites, given its interdomain nature. It also introduces split-horizon rules to help ensure that traffic entering the BGW from one flood domain does not return to the same flood domain. Additional Communities This is used on top of Set Community when multiple communities need to be set. This means all L3Outs on the same border leaf in the same VRF tries to allow the summarized prefix due to the shared route map. This ability to negotiate the trunking method with the other device is called Dynamic Trunking Protocol (DTP), the precursor to DTP is a protocol called Dynamic ISL (DISL). Cisco ACI cannot detect this movement if the endpoint moves to an L3Out connection. One (the green group in Figure 73) is for options to manipulate the routing table and routing protocol via IP prefix-lists and route maps on a border leaf. The following steps are the summary to deploy a routing protocol on an ACI border leaf with the components shown in Figure 4. a. On the other hand, a switch-to-switch link that has been allowed to negotiate its behavior can operate at 10Mb Half Duplex. An option to apply a Route Profile to interleak was introduced in APIC Release 1.2(2). It converts the BGW to a traditional VTEP (the PIP address stays up). The source IP address is not learned as a local endpoint. Also, remember that, as of publication time, only members of the 7500, 7200, 4700, 4500, and 3600 router families support MLS externally. show port - see the status (connected, notconnect, and do on), speed, duplex for all ports on the switch, show logging - see what type of messages generate logging output, set logging level spantree 7 - sets the switch to log the spanning tree port, states real time on the console, set port disable 2/1 - turn the port off in software (like "shutdown" on the router), set port enable 2/1 - turn the port on in software (like "no shutdown" on the router), show time - show the current time in seconds (used at the start of a timing test), show port capabilities - see what features are implemented on the port, set trunk 2/1 off - set the trunking mode to off (to speed port initialization time), set port channel 2/1-2 off - set the EtherChannel (PAgP) mode to off (to speed port initialization time), set port speed 2/1 100 - set the port to 100Mbps and turn off auto negotiation, set port duplex 2/1 full - set the port duplex to full, service timestamps debug uptime - show the time with the debug messages, service timestamps log uptime - show the time with the logging messages, debug spantree events - show when the port moves through the spanning tree stages, show clock - to see the current time (for the timing tests), no shut - to turn on a port from software. Please check the subsection Route Profile on Interleak in the section L3Out Route Profile / Route Map. the destination port is in a local switch or in a remote switch. This is the command. If customers use a Cisco ACI software image, they must convert the SKU from a Product Activation Key (PAK) to Smart License and consume it from the product in the Smart License mode. The Cisco StackWise Virtual active switch runs the STP. See the Basic configuration example above for details. A switch allows multiple devices to be connected to the same network, just like a hub does, but this is where the similarity ends. It is best to set each side for the EtherChannel desirable mode if you want to use EtherChannel. Type of Track List threshold This can be either Percentage or Weight. The Endpoint Dataplane Learning setting on the PBR node EPG is automatically disabled during service graph instantiation. This behavior is originally triggered by the spine when the spine couldnt find the unknown IP, even in the COOP database. There are two elements in Route Profile for L3Out EPG. On the Catalyst 5000, only certain ports can be put together into a channel. have equivalent data plane entry for each forwarding entity. Define a network statement to advertise the default route to BGP. In addition, in a QoS service policy attached to the 10720 control plane, the police command does not support set actions as arguments in conform-action, exceed-action, and violate-action parameters.. (the default algorithm is source-destination IP). It focuses on specific use cases for endpoint IP address learning behavior. Bridge domainlevel configuration options. BGP Address Family Context Policy in GUI (APIC Release 3.2). Metric Style EIGRP calculates its metric based on bandwidth and delay along with default K values. When a subinterface is used, a subinterface is created with this Encap VLAN. The difference is the following: Tenant-level Route Profile: for interleak (redistribution from OSPF or EIGRP to the infra MP-BGP) and BGP Route Dampening, L3Out-level Route Profile: for anything else. Spanning tree can shut down some ports (with a port status of "errdisable") if one side is configured as a channel before the other side can be configured as a channel. The Endpoint Dataplane Learning option was introduced in Cisco APIC Release 2.0(1m). switch where they are processed. There are different methods of trunking dependent upon the media that is used. The Classification and Marking - Port Based section explains the port based configuration. When this feature is enabled, Cisco ACI flushes all local IP endpoints outside bridge domain subnets and all remote IP endpoints. Unspecified The Network Type is unspecified and takes a default value, which is broadcast. However, the same goal can be accomplished by just keeping the default L3Out configuration, which has Import Route Control Enforcement disabled. The route targets must be enabled for the IPv4/IPv6 address family and specifically for EVPN. EVPN Multi-Site architecture allows both modes to be configured. Once the routing protocol is selected, some parameters such as OSPF area number or EIGRP AS number configurations show up in the same window. 4. Another way to verify the channel state is this. Shaped mode weights override the shared mode value. In addition, in a QoS service policy attached to the 10720 control plane, the police command does not support set actions as arguments in conform-action, exceed-action, and violate-action parameters.. session. This section covers these topics: This is how the switch treats frames by default after the QoS is enabled: A frame enters the switch port and it does not have the frame tagged (it means the port is access port and the frame enters the switch does not have ISL or dot1q encapsulation). Next-hop Self This feature allows ACI to update the next-hop when advertising a route from eBGP peer to iBGP peer. show version - to display what version of software the switch runs.
