It is a layer-3 link, and should be a part of a dedicated VRF. We recommend that you create each vPC domain within the contiguous Layer 2 network with a unique domain ID.

 

You should create a separate Layer 2 trunk port-channel between peer switches to transport non-vPC VLAN traffic.The vPC number that you assign to the port channel connecting to the downstream device from the vPC peer device must be identical on both vPC peer devices.

 

Do not use VPC to connect more than two Data Centers. You should go for OTV for that.First Name.

 

Use multiple line cards for VPC peer-link.Use layer3 infrastructure as a 3rd a option for all kind of Nexus Switches.

 

Use dedicated link for keep-alive.In the case of a vPC peer switch total failurethe remote switch learns from the failure via the Peer Keepalive link since no keepalive messages are received.

List of vPC Best Practices · You cannnot build a vPC where one end of the port channel is split across two VDC's of one Nexus switch. · The vPC domain ID should.These features enable the device to avoid a routing-table lookup when responding to a request that originated from a host that is not locally attached to the same subnet.

 

vPC architecture components & troubleshooting for Cisco Nexus , , It is generally good practice to keep the port-channel (e.g. port-channel 10).This feature enables local forwarding of packets without the need to cross the vPC Peer-Link.

 

The configuration must match on both switches; Use the same value for the port channel ID and the vPC ID; If the connected device is another Nexus switch, leave.You can use any module in the device for these port channels.

 

A vPC is an L2 port type: switchport mode trunk or switchport mode access. vPC Peer Switch, A vPC switch (one of a Cisco Nexus / Series.Step 5 exit Example: switch config-vpc-domain exit switch Exits vpc-domain configuration mode.

The host interfaces on this FEX are configured as port channels and those port channels are configured as vPCs.

 

VLAN Mapping.

 

Use the show vpc statistics command to display vPC statistics.

 

The ip arp synchronize feature allows the synchronization of the ARP table when the peer-link comes up.

forum? It must be 10GbE.

 

Figure 6.

 

Depending upon the number of hops to reach the source, this operation might take some time PIM is a hop-by-hop protocol.

 

Brings down all the downstream vPCs on that vPC peer device, which forces all the traffic to be rerouted in the access switch toward the other vPC peer device.

 

Always enable auto-recovery.

 

Migrating from Cisco Nexus switches to Cisco Nexus switches for the need of more interfaces is a typical example of such migration.

 

Always check the existing configured role priority before configuring vPC hitless role change feature.

 

The vPC peer-keepalive path should be robust, and should use a port other than the vPC peer link.

 

Yes it is terse: it is supposed to be a checklist, and I tried to keep it short.Forum Vpc best practices nexus 9000

 

You must save this setting in the startup configuration.
