Switch Clustering

Using Switch Clustering
◆ A switch cluster has a primary unit called the “Commander” which is
used to manage all other “Member” switches in the cluster. The
management station uses both Telnet and the web interface to
communicate directly with the Commander through its IP address,
while the Commander manages Member switches using the cluster’s
“internal” IP addresses.
◆ Clustered switches must be in the same Ethernet broadcast domain. In
other words, clustering only functions for switches which can pass
information between the Commander and potential Candidates or
active Members through VLAN 4093.
◆ Once a switch has been configured to be a cluster Commander, it
automatically discovers other cluster-enabled switches in the network.
These “Candidate” switches only become cluster Members when
manually selected by the administrator through the management
station.
N OTE :
Cluster Member switches can be managed either through a Telnet
connection to the Commander, or through a web management connection
to the Commander. When using a console connection, from the
Commander CLI prompt, use the rcommand to connect to the Member
switch.
cluster This command enables clustering on the switch. Use the no form to disable
clustering.

◆ To create a switch cluster, first be sure that clustering is enabled on the
switch (the default is enabled), then set the switch as a Cluster
Commander. Set a Cluster IP Pool that does not conflict with any other
