Client Isolation Mode

Note: You must create the same isolation mode on both cluster devices. The CLI allows modification of the client isolation mode on MCT cluster devices even when the cluster is deployed.

MCT cluster devices can operate in two modes. Both peer devices must be configured in the same mode.

Loose mode (default): When the CCP goes down, the peer device performs the active/standby negotiation. After negotiation, the standby shuts down its peer ports, but the active peer ports continue to forward traffic if a keep-alive VLAN is configured. If a keep-alive VLAN is not configured, both peer devices become active, and both of the client ports stay up.

Strict mode: When the CCP goes down, the interfaces on both the cluster devices are administratively shut down. In this mode, the client is completely isolated from the network if the CCP is not operational.
