The following procedure describes how to set the current time zone using
timezone_fmt mode to Central Standard time.
1.
Log on to the chassis using the admin account. The default password is
password
2. Enter the tsTimeZone command as follows:
switch:admin> tstimezone [--interactive]/ [, timezone_fmt]
Use timezone_fmt to set the time zone by Country/City or by time zone ID,
such as PST. The following example shows how to change the time zone to
US/Central.
switch:admin> tstimezone_fmt
Time Zone : US/Pacific
switch:admin>
tstimezone US/Central
switch:admin> tstimezone
Time Zone : US/Central
The following procedure describes how to set the current time zone using
interactive mode to Pacific Standard Time.
1. Enter the
tsTimeZone
command as follows:
switch:admin> tstimezone --interactive
2. You are prompted to select a general location.
Please identify a location so that time zone rules can be set correctly.
3. Enter the appropriate number or Ctrl+D to quit.
4.
At the prompt, select a
country location
.
5. At the prompt, enter the appropriate number to specify the time zone region or
Ctrl+D to quit.
Synchronizing local time
To synchronize the local time of the principal or primary switch with that of an
external NTP server, follow these steps.
1. If necessary, log on to the switch by Telnet, using the admin account.
2. Enter the tsClockServer command:
switch:admin> tsclockserver "<ntp1;ntp2>"
where ntp1 is the IP address or DNS name of the first NTP server, which the
switch must be able to access. The variable ntp2 is the second NTP server and
is optional. The operand "<ntp1;ntp2>" is optional; by default, this value is
LOCL, which uses the local clock of the principal or primary switch as the
clock server.
The
tsClockServer command accepts multiple server addresses in either IPv4,
IPv6, or DNS name formats. When multiple NTP server addresses are passed,
tsClockServer sets the first obtainable address as the active NTP server. The
others will be stored as backup servers that can take over if the active NTP
server fails. The principal or primary FCS switch synchronizes its time with the
NTP server every 64 seconds.
switch:admin> tsclockserver
LOCL
switch:admin>
tsclockserver "132.163.135.131"
switch:admin> tsclockserver
132.163.135.131
switch:admin>
The following example shows how to set up more than one NTP server using a
DNS name:
