How to verify optical power level in a SFP inserted in a cisco 3800

Hi all,

I have a Cisco3800 with IOS Version 12.3(14)T2 and I have an HWIC-1GE-SFP module inserted on it.  

I need to know if there is a command to verify optical power level in this module inserted in the Cisco 3800 router?

Something similar to the following command that I can execute in an Cisco ASR9K:

show controllers Te0/0/0/1 phy | i Rx

Thanks in advance for your answers.

Hi William,

It is "show interfaces ... transceiver detail" command.

That is DOM. It's only supported on certain modules, and likely not supported on the 3800 at all.

Paolo, you are right, DOM is not supported on this HWIC:


Minimum Software Release Required

Platform

Switch or Module  

Transceiver Module 

DOM Support

Cisco IOS Release

HWIC-1GE-SFP

GLC-T
GLC-SX-MM
GLC-LH-SM
GLC-ZX-SM
CWDM SFP
GLC-SX-MMD
GLC-LH-SMD

12.3(8)T4

The card with DOM support is EHWIC-1GE-SFP-CU and it is supported on ISR-G2 only.

DOM support provides optical levels, including such commands as:


     show int transceiver detail

     show int transceiver

     show controller | incl Diag

I am facing this issue while I am using following comand on 3900 series router which comand should I Use to check optical power on this router ????

DLHIPDNGAMR001#sh interfaces Gi0/1/0 transceiver detail
Module 0 doesn't support DOM

DLHIPDNGAMR001#sh interfaces Gi0/0 transceiver detail
Module 0 doesn't support DOM

Hi William:

Try this
show hw-module subslot 0/0 transceiver 1 status

Thanks bro...

works well

On the Catalyst 9300 you can perform.

# show interfaces transceiver detail.

 

This command will show the temperature, voltage, current, decibel levels, and thresholds.
