Cisco Nexus 5000 Series Nx-Os Layer 2 Switching Configuration Guide, Release 5.0(3)N1(1 - Cisco Nexus 5000 Series Configuration Manual

Configuring Virtual Port Channels
Before You Begin
Ensure that you have enabled the vPC feature.
You must configure the vPC peer-keepalive link before the system can form the vPC peer link.
You must configure both switches on either side of the vPC peer link with the following procedure.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# vpc domain domain-id
3. switch(config-vpc-domain)# peer-keepalive destination ipaddress [hold-timeout secs | interval msecs
{timeout secs} | precedence {prec-value | network | internet | critical | flash-override | flash | immediate
priority | routine} | tos {tos-value | max-reliability | max-throughput | min-delay | min-monetary-cost
| normal} | tos-byte tos-byte-value} | source ipaddress | vrf {name | management vpc-keepalive}]
4. (Optional) switch(config-vpc-domain)# vpc peer-keepalive destination ipaddress source ipaddress
5. (Optional) switch# show vpc peer-keepalive
6. (Optional) switch# copy running-config startup-config

Configuring a vPC Keepalive Link and Messages
Purpose
Enters configuration mode.
Creates a vPC domain on the switch if it does not already
exist, and enters the vpc-domain configuration mode.
Configures the IPv4 address for the remote end of the vPC
peer-keepalive link.
The system does not form the vPC peer link until
Note
you configure a vPC peer-keepalive link.
The management ports and VRF are the defaults
(Optional)
Configures a separate VRF instance and puts a Layer 3 port
from each vPC peer device into that VRF for the vPC
peer-keepalive link.
(Optional)
Displays information about the configuration for the
keepalive messages.
(Optional)
Copies the running configuration to the startup
configuration.
