client-isolation

Isolates the client from the network when Cluster Communication Protocol (CCP) is not operational.
Syntax
client-isolation strict
no client-isolation strict
Command Default

Client isolation is in loose mode.

Parameters
strict
Specifies the strict isolation mode.
Modes

Cluster configuration mode

Usage Guidelines

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

In loose mode (default), when the CCP goes down, the peer device performs the master/slave negotiation. After negotiation, the slave shuts down its peer ports, whereas the master peer ports continue to forward the traffic (keep-alive VLAN configured).

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

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

The no form of the command sets client isolation mode back to loose mode.

Examples

The following example shows how to configure the client isolation strict mode. 

device(config)# cluster SX 4000
device(config-cluster-SX)# client-isolation strict
