Paging a switch, Managing the date and time

Page 51 highlights

The restore process replaces all configuration information on the switch and afterwards the switch is automatically reset. If the restore process changes the IP address, all management sessions are terminated. Use the set setup system command to return the IP configuration to the values you want. To restore the switch, open a Telnet session (a new IP address may be required), then enter the config restore command from in an Admin session, as shown in the following example: 8/20q FC Switch #> admin start 8/20q FC Switch (admin) #> config restore The switch will be reset after restoring the configuration. Please confirm (y/n): [n] y Alarm Msg: [day month date time year][A1005.0021][SM][Configuration is being restored - this could take several minutes] Alarm Msg: [day month date time year][A1000.000A][SM][The switch will be reset in 3 seconds due to a config restore] 8/20q FC Switch (admin) #> Alarm Msg: [day month date time year][A1000.0005][SM][The switch is being reset] Paging a switch To help you locate a particular switch in a rack of switches, you can turn on the beacon feature with the set beacon command. This causes all port Logged-In LEDs to flash in unison. The following is an example of how to turn the beacon on and off: 8/20q FC Switch #> set beacon on 8/20q FC Switch $> set beacon off Managing the date and time The switch date and time can be set explicitly using the date command or it can be set automatically through a Network Time Protocol (NTP) server. The date command also displays the current time. Unlike the date command, the NTP server also synchronizes the date and time on the switch with the date and time on the workstation, which is required for SSL connections. NOTE: To set the date with the date command, the switch NTP client must be disabled. For information about disabling the NTPClientEnabled parameter, see "set setup system" on page 227. If you are using the date command, you can set the time zone using the set timezone command. The default time zone is Universal Time (UTC) also known as Greenwich Mean Time (GMT). Changing the time zone converts the current time to the time in the new time zone. For this reason, if you are not using an NTP server, set the time zone first, then set the date and time. See the following date and time management examples: • Displaying the date and time, page 51 • Setting the date and time explicitly, page 52 • Setting the time through an NTP server, page 53 Displaying the date and time To display the date and time, enter the date command, as shown in the following example: 8/20q FC Switch #> date Mon Apr 07 07:51:24 2008 8/20q Fibre Channel Switch Command Line Interface Guide 51

8/20q Fibre Channel Switch Command Line Interface Guide
51
The restore process replaces all configuration information on the switch and afterwards the switch is
automatically reset. If the restore process changes the IP address, all management sessions are terminated.
Use the
set setup system
command to return the IP configuration to the values you want. To restore
the switch, open a Telnet session (a new IP address may be required), then enter the
config restore
command from in an Admin session, as shown in the following example:
8/20q FC Switch #> admin start
8/20q FC Switch (admin) #> config restore
The switch will be reset after restoring the configuration.
Please confirm (y/n): [n] y
Alarm Msg: [day month date time year][A1005.0021][SM][Configuration is being
restored -
this could take several minutes]
Alarm Msg: [day month date time year][A1000.000A][SM][The switch will be reset
in 3 seconds due to a config restore]
8/20q FC Switch (admin) #>
Alarm Msg: [day month date time year][A1000.0005][SM][The switch is being reset]
Paging a switch
To help you locate a particular switch in a rack of switches, you can turn on the beacon feature with the
set beacon
command. This causes all port Logged-In LEDs to flash in unison. The following is an
example of how to turn the beacon on and off:
8/20q FC Switch #> set beacon on
8/20q FC Switch $> set beacon off
Managing the date and time
The switch date and time can be set explicitly using the
date
command or it can be set automatically
through a Network Time Protocol (NTP) server. The
date
command also displays the current time. Unlike
the
date
command, the NTP server also synchronizes the date and time on the switch with the date and
time on the workstation, which is required for SSL connections.
NOTE:
To set the date with the
date
command, the switch NTP client must be disabled. For information
about disabling the
NTPClientEnabled
parameter, see ”
set setup system
” on page 227.
If you are using the
date
command, you can set the time zone using the
set timezone
command. The
default time zone is Universal Time (UTC) also known as Greenwich Mean Time (GMT). Changing the time
zone converts the current time to the time in the new time zone. For this reason, if you are not using an NTP
server, set the time zone first, then set the date and time.
See the following date and time management examples:
Displaying the date and time
, page 51
Setting the date and time explicitly
, page 52
Setting the time through an NTP server
, page 53
Displaying the date and time
To display the date and time, enter the
date
command, as shown in the following example:
8/20q FC Switch #> date
Mon Apr 07 07:51:24 2008
