Switch Clustering

S C
WITCH LUSTERING
Switch Clustering is a method of grouping switches together to enable
centralized management through a single unit. Switches that support
clustering can be grouped together regardless of physical location or switch
type, as long as they are connected to the same local network.

Table 52: Switch Cluster Commands

Command Function
cluster Configures clustering on the switch
cluster commander Configures the switch as a cluster Commander
cluster ip-pool Sets the cluster IP address pool for Members
cluster member Sets Candidate switches as cluster members
rcommand Provides configuration access to Member switches
show cluster Displays the switch clustering status
show cluster members Displays current cluster Members
show cluster candidates Displays current cluster Candidates in the network
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 can use either Telnet or the web interface to
communicate directly with the Commander through its IP address, and
then use the Commander to manage the Member switches through 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.
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
switch.
