Adding a switch to a stack as a new member
HP Networking stacking allows for switches to be added to the stack while the stack is operational
(as long as the maximum number of ten switches in the stack is not exceeded).
1. Provision the stack for the new switch by entering the following command:
HP Switch(config)#: stacking member N type JxxxxA [mac MAC-Addr]
where:
• N is the stacking member number for the switch
• JxxxxA is the product number of the switch (required). Any of the HP 3800
models can be installed and assume this provisioned configuration. If you
specify a value for this parameter, then only a switch of this specific model
type can assume this provisioned configuration
• (Optional) MAC-Addr can be specified if you want a specific switch to assume
this provisioned configuration. If this value is entered, then the type value for
the switch that has this MAC address must be correct, or a configuration error
is logged and the switch is not allowed to join the stack.
• (Optional) You can pre-configure a priority for the member switch by entering
this command:
HP Switch(config)#: stacking member N priority 100
Where:
◦ N is the stacking member number for the switch.
◦ X is the priority (1 - 255, but it should be less than the priority assigned
to the Commander. The priority for the Standby should be the second
highest in the stack. The member switches can be left at the default priority
value of 128.)
NOTE: You must configure the type and the priority separately.
NOTE: When the new switch has been provisioned in the stack, a complete
configuration can be applied to the switch even before it is physically connected
to the stack, connected to the network, and powered up.
2. Power on the new switch. The new switch does not become a member of the stack unless
stacking has been enabled on the switch.
3. Install a Stacking Module into the new switch, connect the switch into the stack via the stacking
cables, and form the desired stacking topology.
4. When the switch has finished booting, establish a console session with it and, from the config
context, issue the command to enable stacking:
HP Switch(config)#: stacking enable
This causes the switch to reboot. When the reboot is complete, the switch is a member of the
stack with the attributes that you provisioned for it.
5. Confirm that the switch is now a member of the stack by issuing a show stacking command
via a console session with any of the switches in the stack. The command output should show
that the new switch is a Standby or Member of the stack with the member number and priority
that you assigned to it.
