switch# configure terminal
Entering configuration mode terminal
3. Enter the ntp server "IPv4 address" command, where IPv4 address is the IP address of the first NTP server in
IPv4 format, which the switch must be able to access. The IPv4 address variable is optional. By default, this
value is LOCL, which uses the local clock of the principal switch as the clock server.
switch:config# ntp server "132.163.135.131"
To display the NTP server IP address, use the show ntp status [rbridge-id rbridge-id | all] command. If you are in
config mode, you must use do before the show command.
switch:config# do show ntp status rbridge-id 1
The request is for the local switch unless an Rbridge ID is specified. Specify the all parameter to send the
request to all switches in the cluster.
If you need to remove an NTP server, use the no form of the ntp server command.
switch:config# no ntp server "132.163.135.131"
Setting the time zone
You must perform this procedure on all switches for which the time zone must be set. However, you only need to set
the time zone once on each switch, because the value is written to nonvolatile memory. While not necessary for
switch operation, setting a time zone is part of ensuring accurate logging and audit tracking. Time zone changes
take effect after a reboot.
Use the clock timezone command to set the time zone.
1. If necessary, log in to the switch using an account assigned to the admin role. Be sure you are in privileged EXEC
mode.
2. Enter the clock timezone region/city command.
The following example changes the time zone to US/Pacific Standard Time.
switch# clock timezone America/Los_Angeles
Setting the clock (date and time)
The following procedure sets the local clock date and time. An active NTP server, if configured, automatically
updates and overrides the local clock time. Time values are limited to between January 1, 1970 and January 19,
2038.
NOTE
You should set the clock only if there are no NTP servers configured. Time synchronization from NTP servers overrides
the local clock.
1. If necessary, log in to the switch using the default password (the default password is password). Be sure you are
in privileged EXEC mode.
2. Enter the clock set year-month-dayT hours:minutes:seconds command.
The following example sets the clock to March 17, 2012, 15 minutes past noon.
switch# clock set 2012-03-17T12:15:00
