show network-clocks

To display the current configured and active network clock sources, use the show network-clocks privileged EXEC command.

show network-clocks

Syntax Description

This command has no arguments or keywords.

Command Mode

Privileged EXEC

Command History

Release	Modification
11.3 MA	This command was first introduced.

Usage Guidelines

This command applies to Voice over Frame Relay, Voice over ATM, and Voice over HDLC on the Cisco MC3810.

The Cisco MC3810 has a background task that verifies every 120 seconds whether a valid clocking configuration exists. If this task detects an error, you will be reminded every 120 seconds until the error is corrected. A clocking configuration error may be generated for various reasons. Using the show network-clocks command, you can display the clocking configuration status.

Sample Displays

The following is sample output from the show network-clocks command on the Cisco MC3810:

router# show network-clocks

Priority 1 clock source(inactive config) : T1 0

Priority 1 clock source(active config) : T1 0

Clock switch delay: 10

Clock restore delay: 10

T1 0 is clocking system bus for 9319 seconds.

Run Priority Queue: controller0

In this display, inactive configuration is the new configuration that has been established. Active configuration is the run-time configuration. Should an error be made in the new configuration, the inactive and active configurations will be different. In the above example, the clock priority configuration is valid, and the system is being clocked as indicated.

The following is another sample output from the show network-clocks command:

router# show network-clocks

Priority 1 clock source(inactive config) : T1 0

Priority 2 clock source(inactive config) : T1 1

Priority 1 clock source(active config) : T1 0

Clock switch delay: 10

Clock restore delay: 10

T1 0 is clocking system bus for 9319 seconds.

Run Priority Queue: controller0

In this display, the new clocking configuration has an error for controller T1 1. This is indicated by checking differences between the last valid configuration (active) and the new proposed configuration (inactive). The error may result from hardware (the system controller board or MFT) unable to support this mode, or controller T1 1 is currently configured as "clock source internal."

Since the active and inactive configurations are different, the system will periodically display the warning message about the faulty configuration.

Command	Description
network-clock-select	Sets the selection priority for one or more clock sources for the Cisco .MC3810.
