Show Clock Frames

To display information about the midplane TDM clock reference, use the show frame-clocksprivileged EXEC command.

show frame-clocks

The following sample output from the show frame-clockscommand shows that there are no clock sources configured and the clock card is the default clock source:

Router# show frame-clocks

Priority 1 clock source:not configured input:none

Priority 2 clock source:not configured input:none

Priority 3 clock source:not configured input:none

Priority 4 clock source:not configured input:none

Current clock source:Clockcard, input:Primary, priority:5

Table 4-34 describes the fields shown in the show frame-clocksdisplay:

Priority 1-4 clock source

The configuration of the four network clock sources.

 

 

Current clock source

The current clock source, its input, and priority. In this

 

example, the clock card is providing the clock source.

 

 

Show General Information

To display general information about the router when reporting a problem, use the show tech-supportprivileged EXEC command.

show tech-support[page] [<password>]

The page option causes the output to display a page of information at a time. Use the Return key to display the next line of output or use the space bar to display the next page of information. If not used, the output scrolls (that is, does not stop for page breaks).

The password option leaves passwords and other security information in the output. If not used, passwords and other security-sensitive information in the output are replaced with the label “<removed>” (this is the default).

Use this command to help collect general information about the router when you are reporting a problem. This command displays the equivalent of the following show commands:

show buffers

show controllers

show interfaces

show running-config

show processes cpu

show processes memory

show stacks

show version
