Chapter 7
Administering the Switch
Beginning in privileged EXEC mode, follow these steps to configure a specific interface from which the IP
source address is to be taken:
Command
Step 1
configure terminal
Step 2
ntp source type number
Step 3
end
Step 4
show running-config
Step 5
copy running-config startup-config
The specified interface is used for the source address for all packets sent to all destinations. If a source address
is to be used for a specific association, use the source keyword in the ntp peer or ntp server global
configuration command as described in the
Displaying the NTP Configuration
You can use two privileged EXEC commands to display NTP information:

•
For detailed information about the fields in these displays, refer to the Cisco IOS Configuration
Fundamentals Command Reference for Release 12.1.
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 which the switch can synchronize,
you do not need to manually set the system clock.
