Excluding Vlan Interfaces From Shutting Down A Vpc Peer Link Fails - Cisco nexus 5000 series Configuration Manual

Configuring Virtual Port Channels
Command or Action
Step 4
switch# copy running-config startup-config
This example shows how to configure the delay reload time for a vPC link:
switch(config)# vpc domain 1
switch(config-vpc-domain)# delay restore 10
switch(config-vpc-domain)#

Excluding VLAN Interfaces from Shutting Down a vPC Peer Link Fails

When a vPC peer-link is lost, the vPC secondary switch suspends its vPC member ports and its switch virtual
interface (SVI) interfaces. All Layer 3 forwarding is disabled for all VLANs on the vPC secondary switch.
You can exclude specific SVI interfaces so that they are not suspended.
Before You Begin
Ensure that the VLAN interfaces have been configured.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# vpc domain domain-id
3. switch(config-vpc-domain))# dual-active exclude interface-vlan range
DETAILED STEPS
Command or Action
Step 1 switch# configure terminal
Step 2 switch(config)# vpc domain domain-id
Step 3
switch(config-vpc-domain))# dual-active
exclude interface-vlan range
This example shows how to keep the interfaces on VLAN 10 up on the vPC peer switch if a peer link fails:
switch# configure terminal
switch(config)# vpc domain 5
switch(config-vpc-domain)# dual-active exclude interface-vlan 10
switch(config-vpc-domain)#

Excluding VLAN Interfaces from Shutting Down a vPC Peer Link Fails
Purpose
(Optional)
Copies the running configuration to the startup configuration.
Purpose
Enters global configuration mode.
Creates a vPC domain on the switch if it does not already exist, and
enters vpc-domain configuration mode.
Specifies the VLAN interfaces that should remain up when a vPC
peer-link is lost.
range—Range of VLAN interfaces that you want to exclude from
shutting down. The range is from 1 to 4094.
