[nsp] 3 Port Gige Sync Loss on GSR

[Ash Garg]

Has anyone see the following message from their GSRs?

%GRPGE-6-SYNC_LOSS: Interface GigabitEthernet0/1: Loss of Sync


-----------------
>From cisco.com

Error Message

%GRPGE-6-SYNC_LOSS
: Interface [chars]: [chars]
Explanation   A GBIC loss of synchronization error was detected or is gone
as specified in the message.

Recommended Action   Check the GBIC and cable connections. A local Rx cable
must be connected to the remote Tx cable and vice versa.

We have a number of these beasties in the network all with 3 port gig's and
they seem to be sending the above message at reasonably regular intervals
(roughly 1 per week per gsr). The line card details are:

It does not cause a link up/down or even stop passing traffic and seems like
a cosmetic issue. We have a TAC case open since Nov 2002 with zero results.
Power measurements show that we are well within the optical budgets. The
fibre ends have been cleaned, the gbics replaced, the ports changed and the
card has been relaced and moved to different slots, All with no luck. (ohh
and the tx/rx swap as per cisco.com has been tried as well)

Also IOS upgrades have been done (due to separate issues) and these messages
refuse to go away. I can't seem to find any field notices that may be the
cause. Any one with ideas?


Thanks,
Ash
