Manually Setting the Router Clock

Examples

In the following example, the Management Ethernet interface on the RSP in slot RSP1 is configured with

an IP address:

RP/0/RSP0/CPU0:router# configure

RP/0/RSP0/CPU0:router(config)# interface MgmtEth0/RSP1/CPU0/0

RP/0/RSP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.255.255.0

RP/0/RSP0/CPU0:router(config-if)# no shutdown

RP/0/RSP0/CPU0:router(config-if)# commit

RP/0/RSP0/CPU0:router(config-if)# end

RP/0/RSP0/CPU0:router#

RP/0/RSP0/CPU0:router# show interfaces mgmtEth 0/RSP0/CPU0/0

MgmtEth0/RSP0/CPU0/0 is up, line protocol is up

Manually Setting the Router Clock

Generally, if the system is synchronized by a valid outside timing mechanism, such as a Network Time

Protocol (NTP) or VINES clock source, you need not set the software clock. Use the clock set command

for initial configuration or if a network time source is not available.

The clock timezone command should be entered before the clock is set because it defines the difference

between the system time and Coordinated Universal Time (UTC). When you set the time, you set the

system time, and the router uses the clock timezone command setting to translate that time to UTC. The

system internally keeps time in UTC. When you type the show clock command, the router displays the

system time.
