Cisco Systems AS5400XM quick start Verify Clocking

In the following example, a trunk clock from an 8 PRI CT1 feature card is set at priority 2 and uses slot 4 and ds1 port (controller) 6:

Gateway(config)# dial-tdm-clock priority 2 4/6

Gateway(config)# exit

In the following example, a trunk clock from a CT3 feature card is set at priority 2 and uses slot 1, ds3 port 0, and ds1 port 19:

Gateway(config)# dial-tdm-clock priority 2 1/0:19

Gateway(config)# exit

In the following example, the free-running clock is set at priority 3:

Gateway(config)# dial-tdm-clock priority 3 free

Gateway(config)# exit

Verify Clocking

You can verify the system primary and backup clocks, the status of all trunk feature card controller clocks, and information about and the history of the last 20 TDM clock changes and the events that caused them. Use the following commands.

•T1 or E1 feature card—Verify your default system clocks and clock history by using the show tdm clocks command:

Gateway# show tdm clocks
