Section III: Building a Stack with VCStack Plus 329
Setting the Priority Number
This procedure is optional. It explains how to set the stack priority number
on the chassis, which controls the selection of the active controller card for
the stack. For background information, refer to “Priority Numbers” on
page 311. If you do not want to set the priority number, go to “Powering Off
the Chassis” on page 330.
To configure the priority number, perform the following procedure:
1. Enter the CONFIGURE TERMINAL to move from the Privileged Exec
mode to the Global Configuration mode.
awplus# configure terminal
awplus(config)#
2. Enter the STACK PRIORITY command to set the priority number of
the chassis. The format of the command is as follows:
stack <ID_number> priority <priority_number>
The ID_number variable is the switch’s current ID number, displayed
with the SHOW STACK command. The priority_number variable is the
new priority number for the chassis. The range is 0 to 255. The lower
the number, the higher the priority. This example sets the priority
number of the chassis to 1:
awplus(config)# stack 1 priority 1
The switch displays the following prompt:
% Warning: Stacking is currently disabled.
3. Enter the EXIT command to return to the Privileged Exec mode:
awplus(config)# exit
awplus#
4. Enter the SHOW STACK command to confirm your change. Refer to
Figure 198 on page 328. The Priority column should now be displaying
the new priority number for the chassis.
5. Enter the COPY RUNNING-CONFIG command to save your change:
awplus# copy running-config startup-config
This completes the procedure for configuring the chassis for the stacking
feature. Go to “Powering Off the Chassis” on page 330.
