running on WS1, by duplicating the commands and sending them to the group over the virtual connection. To view status and membership information, refer to the following:

After sending the command to the other members, the cluster-management protocol (at WS1) waits for a response from the members of the redundancy group. Upon receiving a response from each member, WS1 updates the user’s screen and allows the user to enter/execute the next command.

The wait time required to collect responses from other switches is predefined so if any one or more members does not respond to a given command within the defined interval, the command originating switch displays whatever responses have been collected and ignores the delayed responses. This time-based response mechanism eliminates the possibility of indefinite response hangs and allows for quicker redundancy group configuration.

There is no fixed master-slave relationship between members. Typically, a switch can be considered a master for the command it originates. The members that respond to this command can be considered slaves with respect to that command.

This virtual master-slave relationship makes this design unique when compared to existing centralized management systems. Having a virtual master-slave relationship eliminates a single point of failure, since a user can make use of any switch as the group centralized management entity (using the cluster-management
