Configuring the SilkWorm 4100
2
Brocade recommends backing up the configuration on a regular basis to ensure that a complete
configuration is available for downloading to a replacement switch. For specific instructions about
how to back up the configuration, refer to the Fabric OS Procedures Guide. The switchShow,
fabricShow, and configUpload commands are described in detail in the Fabric OS Command
Reference Manual.
Setting the Switch Date and Time
The date and time switch settings are used for logging events. Switch operation does not depend on the
date and time; a switch with an incorrect date and time value still functions properly.
You can synchronize the local time of the principal or primary fabric configuration server (FCS) switch
to that of an external Network Time Protocol (NTP) server.
To set the date and time of a switch:
1. Log in to the switch as admin.
2. Type the date command at the command line using the following syntax:
date “MMDDhhmm[CC]YY”
The values represent the following:
• MM is the month (01-12).
• DD is the date (01-31).
• hh is the hour (00-23).
• mm is minutes (00-59).
• CC is the century (19-20).
• YY is the year (00-99).
Year values greater than 69 are interpreted as 1970-1999; year values less than 70 are interpreted as
2000-2069. The date function does not support Daylight Savings Time or time zones, so changes will
have to be reset manually.
Example
Synchronizing Local Time with an External
Source
Use this procedure to synchronize the local time of the principal or primary FCS switch with that of an
external NTP server:
switch:admin> date
Fri May 5 21:50:00 UTC 1989
switch:admin>
switch:admin> date "0624165203"
Tue Jun 24 16:52:30 UTC 2003
switch:admin>
