Preventing Switch Stack Problems
Note Before continuing to Step 9, power on any connected stack members an d wait unt il they have
completely initialized.
Step9 Write the running configuration to the startup configuration file:
Switch# copy running-config startup-config
The new password is now in the startup configuration.
Note This procedure is likely to leave your switch virtual interface in a shutdown state. You can see
which interface is in this state by entering the show running-config privileged EXEC command.
To re-enable the interface, enter the interface vlan vlan-id global configuration command, and
specify the VLAN ID of the shutdown interface. With the switch in interface configuration
mode, enter the no shutdown command.
Step10 You must now reconfigure the switch. If the system administrator has the backup switch and VLAN
configuration files available, you should use those.
Step11 Reload the switch:
Switch# reload
Preventing Switch Stack Problems
Note • M ake sure that t he switch es that you add to or remove from the sw itch stack ar e powered off. For
all powering considerations in switch stacks, see the “Switch Installation” chapter in the hardware
installation guide.
•After adding or removing stack members, make sure that the switch stack is operating at full
bandwidth (32 Gb/s). Press the Mode button on a stack member until the Stac k mode LED is on. The
last two port LEDs on the switch should be green. Depending on the switch model, the last two ports
are either 10/100/1000 ports or 10-Gigabit Ethernet ports. If o ne or bo th of t he l ast two p ort LE Ds
are not green, the stack is not operating at full bandwidth.
•We recommend using only one CLI session when managing the switch stack. Be careful when using
multiple CLI sessions to the stack master. Commands that you enter in one session are not displayed
in the other sessions. Therefore, it is possible that you might not be able to identify the session from
which you entered a command.
•Manually assigning stack member numbers according to the placement of the switches in the stack
can make it easier to remotely troubleshoot the switch stack. However, you need to remember that
the switches have manually assigned numbers if you add, remove, or rearrange swi tche s la ter. Use
the switch current-stack-member-number renumber new-stack-member-number global
configuration command to manually assign a stack member number. For more information about
stack member numbers, see the “Stack Member Numbers” section on page 5-8.
If you replace a stack member with an identical model, the new switch functions with the exact same
configuration as the replaced switch. This is also assuming the new switch is using the same member
number as the replaced switch.
