Setting the clock (date and time)
The following procedure sets the local clock date and time. An active NTP server, if configured,
automatically updates and overrides the local clock time. Time values are limited to between
January 1, 1970 and January 19, 2038.
NOTE
You should set the clock only if there are no NTP servers configured. Time synchronization from NTP
servers overrides the local clock.
1. Log in to the switch using the default password (the default password is password).
2. Enter the clock set <year>-<month>-<day>T<hours>:<minutes>:<seconds> command.
The following example sets the clock to March 17, 2010, 15 minutes past noon:
switch:admin > clock set 2010-03-17T12:15:00
3. To show the clock and time zone settings, use the show clock [switchid | all]
command.
switch:admin > show clock switchid 1
Setting time zones
You must perform this procedure on all switches for which the time zone must be set. However, you
only need to set the time zone once on each switch, because the value is written to nonvolatile
memory. While not necessary for switch operation, setting a time zone is part of ensuring accurate
logging and audit tracking. Time zone changes take effect after a reboot.
Use the clock TimeZone command to set the time zone.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the clock TimeZone <region>/<city> command.
The following example changes the time zone to US/Pacific Standard Time:
switch:admin > clock timezone America/Los_Angeles
Connecting network devices
Connecting to Ethernet or Fast Ethernet hubs
For copper connections to Ethernet hubs, a 1000Base-T switch, or another Brocade device, a
crossover cable is required. If the hub is equipped with an uplink port, it requires a straight-through
cable instead of a crossover cable.
NOTE
The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic negotiation of the
connection between two 1000Base-T ports. Therefore, a crossover cable may not be required; a
straight-through cable may work as well.
