Cisco ASR 900 command "show interface transceivers" not available

[BorislavPenchev0962]

Hi,

we have one Cisco ASR 900 where we meed to check regular

 show interface transceiver

on Route processor "R0" in State "active" - works for approx 1-2 mins after reboot . but then again:

#show interface tr?

% Unrecognized command

 when we do failover from R0 to R1 (same A900-RSP2A-128), the command also works good

do you think this is a bug?

Best Regards

[marce1000]

 - Looks like  a  bug  . use latest advisory software release on the ASR , if applicable : check if that can help.

according following link: https://www.cisco.com/c/en/us/td/docs/routers/asr903/software/guide/chassis/xe-3s/b_Config_Guide_fullbook/b-cfg-ethernet-int.html

The

show interface transceiver 

command is not supported on the router.

but at the same time we have just taken

show interface transceiver

from another machine with route processor A900-RSP2A-128?

how is this possible ?

Can you post

show version

and

show modules

output.

try below syntax :

show  hw-module subslot x/x  transceiver Y status

show controller tenGigE 0/3/0/0 phy
show controller dwdm 0/3/0/2 optic

[BorislavPenchev0962]

show hw-module 

command gives very summarized output compared to

show interface transceivers

(which is working but only for few minutes after reboot)

only the below options are available when l checked for show controllers:

EZ#show controllers ?
C3794 C37.94 controller information
DCC Show DCC parameters
E1 E1 controller internal state
T1 T1 controller internal state
acr ACR controller information

hello,

l did have checked the following info:

https://www.cisco.com/c/en/us/td/docs/routers/asr903/software/guide/chassis/xe-3s/b_Config_Guide_fullbook/b_Config_Guide_fullbook_chapter_010100.html

and also here:

https://www.cisco.com/c/en/us/td/docs/routers/asr903/software/guide/chassis/xe-3s/b_Config_Guide_fullbook/b-cfg-ethernet-int.html

the command

show interface transceiver

 is an relic from the past and Cisco didn`t delete it completely from the software.

There is no new command who shows you a table from the rx/tx signals of all interfaces, you need to search it one by one with the command

show hw-module

slot/subslot 

transceiver

 port 

idprom status

I was also suspecting this is part of the code which was not cleared, but left in background and thus was allowing it for few minutes initially while switch is still starting;

thanks for support
