Chapter 7 Configuring vPCs Configuring vPCs Send document comments to [email protected] DETAILED STEPS Step 1 Command configure terminal Purpose Enters global configuration mode. Step 2 Step 3 Step 4 Step 5 Example: switch# configure terminal switch(config)# vpc domain domain-id Example: switch(config-if)# vpc domain 5 switch(config-vpc-domain)# Creates a vPC domain if it doesn't already exist, and enters the vpc-domain configuration mode. peer-gateway Example: switch(config-vpc-domain)# peer-gateway Note: ------:: Disable IP redirects on all interface-vlans of this vPC domain for correct operation of this feature ::------ Enables Layer 3 forwarding for packets destined to the peer's gateway MAC address. peer-gateway exclude-vlan backup-vlan-id Example: switch(config-vpc-domain)# peer-gateway exclude-vlan 2 (Optional) Beginning with Cisco NX-OS Release 5.1(3), avoids software switching of transit VLAN traffic in a mixed chassis mode. Note See the "vPC Peer-Gateway" section on page 7-12 for more information. exit Exits the vpc-domain configuration mode. Step 6 Step 7 Example: switch(config-vpc-domain)# exit switch(config)# show vpc brief Example: switch# show vpc brief (Optional) Displays information about each vPC, including information about the vPC peer link. copy running-config startup-config (Optional) Copies the running configuration to the Example: startup configuration. switch# copy running-config startup-config Configuring a Graceful Consistency Check Beginning with Cisco NX-OS Release 5.2(1), you can configure the graceful consistency check feature, which is enabled by default. Unless this feature is enabled, the vPC is completely suspended when a mismatch in a mandatory compatibility parameter is introduced in a working vPC. When this feature is enabled, only the links on the secondary peer device are suspended. See the "Compatibility Parameters for vPC Interfaces" section on page 7-15 for information on consistent configurations on the vPCs.
