Configuring Network Clock
DETAILED STEPS
Configuring Network Clock
At initialization, all controllers on the Cisco IAD2430 IAD, including onboard T1/E1 or VWIC T1/E1,
participate in the system clock domain. The default network clock algorithm selects one of the
controllers as a default network clock. The default network clock algorithm provides a best estimate of
the clocking system. This is mainly for voice applications to be configured easily after power up.
Cisco recommends that when you power up the system, make sure that network clocks are configured
properly for the applications to work, with consideration for the specific network system requirements.
To view the current primary clock, use the
show network-clocks
or
show run
command. Note that the
show network-clocks
and
show run
commands do not display the default network clock, which is
selected by the default network clock algorithm.
Command or Action
Purpose
Step 1
enable
Example:
Router# enable
Enters privileged EXEC mode.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
ip routing
Example:
Router(config)# ip routing
Enables routing protocols as required for your global
configuration. This example uses IP routing.
Step 4
interface
type number
Example:
Router(config)# interface fastethernet 0/0
Enters interface configuration mode. You have entered
interface configuration mode when the prompt changes
to
Router(config-if)#.
Step 5
ip address
ip address subnet mask
Example:
Router(config-if)# ip address 172.16.74.3
255.255.255.0
Assigns an IP address and subnet mask to the interface.
Step 6
exit
Example:
Router(config-if)# exit
Exits to global configuration mode.
Repeat Step 4 through Step 6 if your Cisco IAD has more
than one interface to configure.
Step 7
Ctrl-z
Example:
Router# Ctrl-z
Returns to enable mode when you finish configuring the
interfaces.
