Synchronizing local time using NTP
Perform the following steps to synchronize the local time using NTP.
1. Log in to the switch using the default password (the default password is
password
).
2. 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:admin>
ntp server "132.163.135.131"
To display the NTP server IP address, use the show ntp status [switchid
switchid
| all]
command.
switch:admin>
show ntp status switchid 132.163.135.131
The request is for the local switch unless a switch 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:admin>
no ntp server "132.163.135.131"
Setting the clock (date and time) manually
You should set the clock only if there are no NTP servers configured. Time synchronization from
NTP servers overrides the local clock. Date values are limited to between January 1, 1970 and
January 19, 2038.
1. Log in to the switch using the default password (the default password is
password
).
2. Enter the clock set
year
-
month
-
day
T
hours
:
minutes
:
seconds
command.
The following example sets the clock to March 17, 2010, 15 minutes past noon:
switch:admin >
clock set 2010-03-17T12:15:00
3. To show the clock and time zone settings, use the show clock [switchid
switchid
| all]
command.
switch:admin >
show clock switchid 1
Setting time zones
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. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the clock TimeZone
region
/
city
command.
The following example changes the time zone to US/Pacific Standard Time:
switch:admin >
clock timezone America/Los_Angeles
