Configuring vPCs Chapter 7 Configuring vPCs Send document comments to [email protected] DETAILED STEPS Step 1 Command configure terminal Purpose Enters global configuration mode. Step 2 Example: switch# configure terminal switch(config)# vpc domain domain-id Step 3 Example: switch(config)# vpc domain 5 switch(config-vpc-domain)# peer-switch Example: switch(config-vpc-domain)# peer-switch Step 4 spanning-tree vlan vlan-range priority value Step 5 Example: switch(config)# spanning-tree vlan 1 priority 8192 exit Enters the vPC domain number that you want to configure. The system enters the vpc-domain configuration mode. Enables the vPC switch pair to appear as a single STP root in the Layer 2 topology. Use the no form of the command to disable the peer switch vPC topology. Configures the bridge priority of the VLAN. Valid values are multiples of 4096. The default value is 32768. Exits the vpc-domain configuration mode. Step 6 Step 7 Example: switch(config-vpc-domain)# exit switch(config)# show spanning-tree summary Example: switch# show spanning-tree summary (Optional) Displays a summary of the spanning tree port states including the vPC peer switch. copy running-config startup-config (Optional) Copies the running configuration to the Example: startup configuration. switch# copy running-config startup-config This example shows how to configure a pure vPC peer switch topology: switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. switch(config)# vpc domain 5 switch(config-vpc-domain)# peer-switch 2010 Apr 28 14:44:44 switch %STP-2-VPC_PEERSWITCH_CONFIG_ENABLED: vPC peer-switch configuration is enabled. Please make sure to configure spanning tree "bridge" priority as per recommended guidelines to make vPC peer-switch operational. switch(config-vpc-domain)# exit switch(config)# spanning-tree vlan 1 priority 8192 7-54 Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 5.x OL-23435-03
