Setting the date and time
3
1. Enter switch-attributes followed by the Rbridge ID and the chassis-name operand with the new
chassis name.
If you have changed the rbridge-ID, be sure to use that ID.
switch(config)# switch-attributes 1 chassis-name B8770_prime
2. Record the new name for reference.
3. To verify the new chassis name you can run the show running-config switch-attributes
[rbridge-id] command.
switch# show running-config switch-attributes 1
Setting the date and time
The MM maintains the current date and time inside a battery-backed real-time clock (RTC) circuit.
Date and time are used for logging events. Switch operation does not depend on the date and time;
a Brocade VDX 8770-4 with an incorrect date and time value functions properly. Because the date
and time are used for logging, error detection, and troubleshooting, you should set them correctly.
Time zones
You can set the time zone for a switch by using the clock TimeZone command. The time zone
setting has the following characteristics:
• The time zone setting automatically adjusts for Daylight Savings Time.
• Changing the time zone on a switch updates the local time zone setup and is reflected in local
time calculations.
• By default, all switches are in the Greenwich Mean Time (GMT) time zone (0,0). If all switches
in a fabric are in one time zone, it is possible for you to keep the time zone setup at the default
setting.
• System services that have already started will reflect the time zone changes only after the next
reboot.
• Time zone settings persist across failover for high availability.
• Time zone settings are not affected by Network Time Protocol (NTP) server synchronization.
The following regions are supported: Africa, America, Arctic, Antarctica, Asia, Atlantic, Australia,
Europe, Indian, and Pacific. One of these, along with a city name, establishes the time zone. Refer
to
“Setting the time zone.”
Time synchronization
To keep the time in your network current, it is recommended that each switch has its time
synchronized with at least one external NTP server.
