cluster-track

Configures interface to track state of MCT cluster.

Syntax

cluster-track
[no] cluster-track

Parameters

cluster-track
Configures interface to track state of MCT cluster.

Modes

Interface sub-mode

Usage Guidelines

This command helps reduce convergence for reload cases by diverting traffic to alternate paths. The cluster tracked ports are brought down along with MCT clients for these reasons:

  1. Maintenance mode is enabled or cluster ‘shutdown all.`
  2. Peer-interface goes down on the MCT secondary node, while the peer node is up (split-brain).
  3. Cluster bring-up is in progress after reload .

Once the cluster status comes up, the cluster tracking interfaces are brought up along with the cluster clients. When none of the above conditions are true, the configuration has no effect on the interface state.

When the interface is disabled due to cluster status, admin shut/no shut on the port has no effect. [no cluster-track] removes the cluster-track configuration from the port. This port no longer tracks the status of the MCT cluster.

This command can be configured on L2 or L3 Ethernet or port-channel interfaces. The interface should not be a port channel member and is only valid when cluster configuration is present.

Cluster-track cannot be configured on an interface if it is configured with any of the below:

  1. Peer-interface (under cluster)
  2. Cluster-client
  3. Channel-group
  4. Reload-delay enable

Examples

SLX(config)# int eth 0/3
SLX(conf-if-eth-0/3)# cluster-track
SLX(conf-if-eth-0/3)# do sh run int eth 0/3
interface Ethernet 0/3
description uplink_spine1
cluster-track
switchport
switchport mode trunk
switchport trunk tag native-vlan
no shutdown
 
SLX# show interface ethernet 0/3
Ethernet 0/3 is admin down, line protocol is down (Cluster triggered shutdown)
