Core Isolation tracking is disabled by default. It has to be explicitly enabled using this command.
Interface Configuration Mode (for Ethernet and Port Channel interfaces only).
This command ensures that that the configured single homed edge port interface is brought down along with the ESI interfaces. When the BGP EVPN sessions come up, these tracked single homed edge port interfaces are brought up along with the ESI interfaces to have better data traffic convergence.
This feature is only available when ESI is configured on (at least) a single interface.
Core Isolation Tracking cannot be applied to an interface that is a port-channel member. That is, the interface must not have channel-group configuration present.
The interface on which Core Isolation Tracking is applied to, must not be a multi-homed client. Post this configuration, the tracked interface cannot be assigned as a PO member or a multi-homing client.
During firmware downgrade, core-isolation track configurations are removed.
The following example shows the configuration of Core Isolation Tracking on a port-channel interface.
SLX (config)# interface port-channel 1
SLX (config-Port-channel-1)# core-isolation-track
The following example shows the configuration of Core Isolation Tracking on an ethernet interface.
SLX (config)# interface ethernet 0/1
SLX (config)# core-isolation-track
