Cluster configuration mode
Only one VLAN can be configured as a keep-alive VLAN. The keep-alive VLAN cannot be a member VLAN of the Multi-Chassis Trunking (MCT) and this VLAN can be tagged or untagged.
When the CCP is down, the following results occur:
- If the keep-alive VLAN is configured, CCRR messages are sent every second over that VLAN.
- If no packets are received from the peer device for a period of three seconds, the peer is considered down.
- If a keep-alive VLAN is not configured and both the peer devices are up, both peers continue forwarding traffic independently, when the CCP is down.
Note: Keep-alive VLAN configuration is not allowed when the client isolation mode is strict; and when the keep-alive VLAN is configured, client isolation mode cannot be configured as strict.
The no form of the command removes the keep-alive VLAN configuration.
The following example shows how to configure the keep-alive VLAN.
device(config)# cluster SX 400
device(config-cluster-SX)# keep-alive-vlan 10
