User Manual

Chapter 3. Commands for Cluster 67

www.qtech.ru

 Parameter: <cluster-name> is the cluster’s name, no longer than 32 characters.

 Command mode: Global Mode

 Default: Default setting is no commander switch. cluster_name is null by default.

 Usage Guide: This command sets the role of a switch as commander switch and creates

a cluster, which can only be executed on non commander switches. The cluster_name

cannot be changed after the switch becoming a commander, and “no cluster

commander” should be executed first to do that. The no operation of this command

will cancel the commander configuration of the switch.

 Example: Set the current switch as the commander switch and name the cluster as

switch.

 Switch(config)#cluster commander switch

3.4 cluster ip-pool

 Command: cluster ip-pool <commander-ip>

 no cluster ip-pool

 Function: Configure private IP address pool for member switches of the cluster.

 Parameters：commander-ip: cluster IP address pool for allocating internal IP addresses

of the cluster commander-ip is the head address of the address pool, of which the valid

format is 10.x.x.x, in dotted-decimal notation; the address pool should be big enough to

hold 128 members, which requires the last byte of addresses to be less than 126（254

– 128 = 126）. IP address pool should never be changed with commander configured.

The change can only be done after the “no cluster commander” command being

executed.

 Command mode: Global Mode

 Default: The default address pool is 10.254.254.1.

 Usage Guide: When candidate switches becomes cluster members, the commander

switch allocates a private IP address to each member for the communication within the

cluster, and thus to realized its management and maintenance of cluster members. This

command can only be used on non-commander switches. Once the cluster established,

users can not modify its IP address pool. The NO command of this command will

restore the address pool back to default value, which is 10.254.254.1.

 Example: Set the private IP address pool used by cluster member devices as

10.254.254.10

 Switch(config)#cluster ip-pool 10.254.254.10

3.5 cluster keepalive interval

 Command: cluster keepalive interval <second>

 no cluster keepalive interval

 Function: Configure the interval of keepalive messages within the cluster.

 Parameters: <second>: keepalive interval, in seconds, ranging from 3 to 30.
