Configuring vPCs Chapter 7 Configuring vPCs Send document comments to [email protected] Manually Configuring the System Priority When you create a vPC domain, the system automatically creates a vPC system priority. However, you can also manually configure a system priority for the vPC domain. Note We recommend that you manually configure the vPC system priority when you are running LACP to ensure that the vPC peer devices are the primary devices on LACP. When you manually configure the system priority, ensure that you configure the same priority value on both vPC peer devices. If these values do not match, vPC will not come up. BEFORE YOU BEGIN Ensure that you have enabled the vPC feature. Ensure that you are in the correct VDC (or use the switchto vdc command). SUMMARY STEPS 1. configure terminal 2. vpc domain domain-id 3. system-priority priority 4. exit 5. (Optional) show vpc role 6. (Optional) copy running-config startup-config DETAILED STEPS Step 1 Command configure terminal Purpose Enters global configuration mode. Step 2 Step 3 Step 4 Example: switch# configure terminal switch(config)# vpc domain domain-id Example: switch(config)# vpc domain 5 switch(config-vpc-domain)# Enters the vPC domain number that you want to configure. The system enters the vpc-domain configuration mode. system-priority priority Example: switch(config-vpc-domain)# system-priority 4000 switch(config-vpc-domain)# Enters the system priority that you want for the specified vPC domain. The range of values is from 1 to 65535. The default value is 32667. exit Exits the vpc-domain configuration mode. Example: switch(config-vpc-domain)# exit switch(config)# 7-44 Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 5.x OL-23435-03
