SNMP Polling of optical budget (dbm)

Hi,

 

I can't seem to find an OID to monitor transceiver optics RX/TX as "dbm" on IOS-XR like we can do on catalyst/IOS devices for example

ENTITY-SENSOR-MIB only seems to report celsius/amperes/watts/voltsDC sensors ?

 

thanks

Mik

we are trying to monitor the Cisco 9148s SFP status, and have get the Sensor's dBm value from the CISCO-ENTITY-SENSOR-MIB table, meanwile , it has an Index value like "30000xxxx",such as "30001773",

but we can't sure how to locate the port location from the Index value, what is the mean of the “30000xxxx”, how can i locate it's physical port location? or find the translate rules betwwen the “30000xxxx” and the entPhysicallindex?

 

 

 

Hi,
Physical port location can not be determined from sensor index. I made logic to know port name from sensor object

* Sensor Object
* lane1_power Tx 0/10/CPU0/1 --> Here port name is 0/10/0/1 i.e. grab after TX and replace CPU with empty string.
Once you have port name then you can related it to interface data.

Best regards
Syed

Dear Syed,
Many thanks your help!but we can't find the way to get the TX or RX power with port name from sensor object.
Could we have your great help to know which snmp OID can we grab TX or RX power TX+ lane1_power Tx 0/10/CPU0/1? or can we have your help to share a example?
Many thanks again!

but we can't sure how to locate the port location from the Index value, what is the mean of the “30000xxxx”, how can i locate it's physical port location? or find the translate rules betwwen the “30000xxxx” and the entPhysicallindex?

 

 

 

 

I have exact same issue. Even my Port Supervisors indexes are the same, however I don't know how to match them to 30000XXXX indexes values. Anybody resolved this?
