Troubleshooting the Internal Clock Settings (Lab Environments Only)

If you are using crossover cables to connect to two back-to-back routers in a lab

environment, make sure all interfaces on a given slot have consistent clock source

and speed settings. Messages like the following appear if two interfaces on a slot

have inconsistent clock settings:

Warning Sync Code: 40 “Connector COM2: clock speed does not match other

ports.”

Check the clock source and speed settings as follows:

1. Enter the following command to display the clock source setting for each

slot and connector in the router:

get wfSyncEntry.13.*

The display shows the settings for all synchronous ports on all slots in the

following format:

wfSyncEntry.wfSyncClkSource.

<slot_no.>

<connector_no.>

The setting is 1 for clocking within the router or 2 for clocking from an

external source.

2. If any of the clock source settings are 1 (for internal clocking), enter the

following command to check the clock speed:

get wfSyncEntry.14.*

The console displays the transmission and reception clock speed for each slot

and connector on the router. All ports conﬁgured for internal clocking within a

slot use the clock speed of the port most recently conﬁgured for internal

clocking. The clock speed is valid only for the slots that are set for internal

clocking.

The clock speeds you can set are 1200 (1200b), 2401 (2400b), 4807 (4800b),

7204 (7200b), 9615 (9600b), 19230 (19200b), 32051 (32000b), 38461

(38400b), 56818 (56k), 64102 (64k), 125000 (125k), 227272 (230k), 416666

(420k), 625000 (625k), 833333 (833k), 1250000 (1mb), 2500000 (2mb), and

5000000 (5mb).

Note: All internally clocked ports on a slot change to the last conﬁgured

internal clock speed when you boot, save a dynamic conﬁguration change, or

enter the

conﬁg command.
