Verifying the PID mode

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 rest 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:

switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net" Updating Clock Server configuration...done.

Updated with the NTP servers

Changes to the clock server value on the principal or primary FCS switch are propagated to all switches in the fabric
