IP datagrams and ARP requests and replies on IEEE 802 networks othe r than Ethernet is specified by
the Subnetwork Access Protocol (SNAP). By default, standard Ethernet-style ARP encapsulation
(represented by the arpa keyword) is enabled on the IP interface.
ARP entries added manually to the table do not age and must be manually removed.
How to Perform Switch Administration

Configuring Time and Date Manually

If no other source of time is available, you can manually configure the time and date after the system is
restarted. The time remains accurate until the next system restart. We recommend that you use manual
configuration only as a last resort. If you have an outside source to w hich the switch can synchronize,
you do not need to manually set the system clock.

Setting the System Clock

If you have an outside source on the network that provides time services, such as an NTP server, you do
not need to manually set the system clock.
Beginning in privileged EXEC mode, follow these steps to set the system clock:

Configuring the Time Zone

The minutes-offset variable in the clock timezone global configuration command is available for those
cases where a local time zone is a percentage of an hour different from UTC. For example, the time zone
for some sections of Atlantic Canada (AST) is UTC-3.5, where the 3 means 3 hours and .5 means 50
percent. In this case, the necessary command is clock timezone AST -3 30.
Command Purpose
Step 1 clock set hh:mm:ss day month year
or
clock set hh:mm:ss month day year
Manually sets the system clock using one of these formats:
• hh:mm:ss—Specifies the time in hours (24-hour format), minutes,
and seconds. The time specified is relative to the configured time
zone.
• day—Specifies the day by date in the month.
• month—Specifies the month by name.
• year—Specifies the year (no abbreviation).
