Installation guide

The ntp server command accepts multiple server addresses in either IPv4 or IPv6 format. When
multiple NTP server addresses are passed, ntp server sets the first obtainable address as the active
NTP server. If there are no reachable time servers, then the local time is the default time.
Synchronizing local time using NTP
Perform the following steps to synchronize the local time using NTP.
1. Log on to the device using the admin account (the default password is password).
2. Enter configure terminal to change to global configuration mode.
device# 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 device must be able to access. The IPv4 address variable is
optional. By default, this value is LOCL, which uses the local clock as the clock server.
device(config)# ntp server "132.163.135.131"
To display the NTP server IP address, use the show ntp status rbridge-id rbridge-id command. If
you are in global configuration mode, you must use do before the show command.
device(config)# do show ntp status rbridge-id 1
The request is for the local device unless an RBridge ID is specified. Specify the all parameter to
send the request to all devices in the cluster.
To remove an NTP server, use the no form of the ntp server command.
devic(config)# no ntp server "132.163.135.131"
Setting the time zone
You must perform this procedure on all devices for which the time zone must be set. However, you
only need to set the time zone once on each device, because the value is written to nonvolatile
memory. While not necessary for device operation, setting a time zone is part of ensuring accurate
logging and audit tracking. Time zone changes persist through a reboot without having to save the
current running configuration.
Use the clock timezone command to set the time zone.
1. Log in to the device using an account that has the admin role.
2. Enter the clock timezone region/city command while in privileged EXEC mode.
The following example changes the time zone to US/Pacific Standard Time.
device# 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.
