The ARP table displays the following information:
Clocksource
Description: Displays the source of clocking for the MAX. Clock slips can cause
connectivity problems, particularly for analog users. If you use the Net/T1 > Line Config >
Line # > Clock Source parameter to move the clock source, use this diagnostic command to
validate your changes.
Note:
You need to reboot the MAX to enable any changes to the Clock Source parameter.
Also, if more than one line has Clock Source set to Yes, remember that the clock source will be
derived from the first line that syncs. If you want to ensure that a particular line is the source,
make sure it has Clock Source set to Yes and that all other lines have Clock Source set to No.
Usage: Enter
clocksource
at the command prompt.
Example: In the following example, the clock source is taken from the first T1/PRI line,
designated
dsl 0
.
Dsl#
indicates the maximum number of possible sources for the clock.
The source can be on Net/T1 slot cards. This MAX has three T1/PRI lines configured, so there
are three possible external sources for the clock.
LstSel
is further validation that the clock is
being derived from
Dsl#0
. After
Now
, a 2 indicates that layer 2 is up for that line and is
available as the clock source.

Clock source is dsl 0
