be a switch worked as the command switch, which allows up to 255 switches simultaneously to join the cluster
as member switches. As the single access node in the cluster, the command switch is used to configure,
manage and monitor member switches. One switch belongs to only one cluster at a certain moment.

57.3.1 Planning Cluster
A. VLAN
To manage the switch through the cluster, the command switch, the member switch and candidate switch of a
cluster must have the default VLAN. The interface of the default VLAN of these switches has already existed.
B. Automatically discovering member switches and candidate switches
The command switch uses the BDP protocol to find the member switch, candidate switch and other clusters.
The command switch also uses the BDP protocol to find the network topology. Therefore, you need to run the
BDP protocol on the member switch, candidate switch and other clusters and activate BDP on the
interconnected interfaces.
C. IP address
If the management station accesses the cluster through the TCP/IP management mode, such as telnet, http
and snmp, you need configure the IP address of the command switch that the management station can
access. You need not configure the IP address for the member switch of the cluster.
After the member switch joins in the cluster, the command switch distributes an IP address to each member
switch. These IP addresses are selected from the IP pool of the cluster configured on the command switch.
When planning the address pool, pay attention that the service addresses cannot be the same as those in the
address pool; note that the address number in the address pool cannot be smaller than the maximum number
of member switches in the cluster (including the command switch).

A. Activating command switch
Run the following command in global configuration mode to set the current switch to the command switch:
