Using Recovery Procedures
Step14 Enter global configuration mode:
switch# configure terminal
Step15 Change the password:
switch(config)# enable secret <password>
or
switch(config)# enable password <password>
Step16 Return to privileged EXEC mode:
switch(config)# exit
switch#
Step17 Write the running configuration to the startup configuration file:
switch# copy running-config startup-config
The new password is now included in the startup configuration.
Recovering from a Command Switch Failure
This section describes how to recover from a failed command switch. You can configure a redundant
command switch group by using the Hot Standby Router Protocol (HSRP). For m ore in forma ti on, se e
Chapter 7, “Clustering Switches.”
Note HSRP is the preferred method for supplying redundancy to a cluster.
If you have not configured a standby command switch, and your command switch loses power or fai ls
in some other way, management contact with the member switches is lost, and you must install a new
command switch. However, connectivity between switches that are still connecte d is not affected , and
the member switches forward packets as usual. You can manage the members as standalone switches
through the console port or, if they have IP addresses, through the other mana geme nt i n terface s.
You can prepare for a command switch failure by assigning an IP address to a member switch or another
switch that is command-capable, making a note of the command-switch password, and cabling your
cluster to have redundant connectivity between the member switches and the replacement comm and
switch. This section describes two solutions for replacing a faile d com ma nd sw it ch:
•Replacing a failed command switch with a cluster member
•Replacing a failed command switch with another switch
For information on command-capable switches, refer to the release notes.
