Setting The Date; Setting The Time Zone - IBM 2498-B40 Service Information

external NTP server. The other switches in the fabric will automatically take their
time from the principal or primary FCS switch.
All switches in the fabric maintain the current clock server value in non-volatile
memory. By default, this value is the local clock server <LOCL> of the principal or
primary FCS switch. Changes to the clock server value on the principal or primary
FCS switch are propagated to all switches in the fabric.
When a new switch enters the fabric, the time server daemon of the principal or
primary FCS switch sends out the addresses of all existing clock servers and the
time to the new switch. If a switch with v5.3.0 or later has entered the fabric it will
be able to store the list and the active servers; pre-5.3.0 Fabric OS switches will
ignore the new list parameter in the payload and will update only the active server
address.
If the active NTP server configured is IPv6, then distributing the same in the fabric
will not be possible to switches earlier than v5.3.0 because IPv6 is supported for
Fabric OS version 5.3.0 and later. The default value LOCL will be distributed to
pre-5.3.0 switches.
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
are 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.

Setting the date

1. Log into the switch using the default password, which is password.
2. Enter the date command, using the following syntax:
date ""mmddHHMMyy""
The values represent the following:
v mm is the month; valid values are 01 through 12
v dd is the date; valid values are 01 through 31
v HH is the hour; valid values are 00 through 23
v MM is minutes; valid values are 00 through 59
v yy is the year; valid values are 00 through 99 (values greater than 69 are
interpreted as 1970 through 1999, and values less than 70 are interpreted as
2000-2069)

Setting the time zone

To set the time zone, follow these steps.
1. Log into the switch using the default password, which is password.
2. Enter the tsTimeZone command as follows:
switch:admin> tstimezone [--interactive]/ [, timezone_fmt]
