WS-C4948-10GE disable Rx/Tx power alarm

Hi guys,

recently we replaced our cat3750 boxes with WS-C4948-10GE. Everything works great, but we are distracted by log entries like this:

000510: Aug 16 07:07:17.985 UTC: %SFF8472-5-THRESHOLD_VIOLATION: Te1/50: Rx power low alarm; Operating value: -40.0 dBm, Threshold value: -18.4 dBm.

000511: Aug 16 07:07:17.985 UTC: %SFF8472-5-THRESHOLD_VIOLATION: Te1/50: Tx power high alarm; Operating value:   6.3 dBm, Threshold value:   4.4 dBm.

I know it is useful for monitoring purposes but since there's X2 to SFP+ converter with SFP+ metalic interconnect cable inserted in Te1/50, these values are unnecessary for us. Is there any way to disable these alarms on per port basis?

Thanks a lot!

Re: WS-C4948-10GE disable Rx/Tx power alarm

Ok, I'll reply to myself Since there is probably no possibility to turn it explicitly off, the only solution is to suppress log messages via logging discriminator, e.g.:

logging discriminator TEUTPthr msg-body drops "^.*Te1/50.*(low|high) alarm.*$"

logging buffered discriminator TEUTPthr 1024000

If you are logging to remote syslog host, you can set up similar filter there (AFAIK syslog-ng allows it). Hope it will help somebody later
