How to check optical power on Maestro Orchestrators and SGMs

[rahulctg]

Hi,

Could someone help me with the command to check the optical powers on the MHO ports and SGMs please? 

[Expert@MHO:0]# ethtool -m dl121
Cannot get module EEPROM information: Operation not supported
[Expert@MHO:0]#
[Expert@MHO:0]# ethtool -m 1/31/1
Cannot get module EEPROM information: No such device
[Expert@MHO:0]#

[Expert@MHO:0]# mii-diag -g dl65
SIOCGMIIPHY on dl65 failed: Operation not supported
[Expert@MHO:0]#

[Expert@MHO:0]# ifconfig dl121

Is this R81.20 and have you tried:

show interface <Name of Interface> xcvr

show interface <Name of Interface> xcvr_detail

Hi Chris,

I tried as well.

I think the command is under 'show maestro port X/Y/Z optic-info' or like that, tab through it and you'll find it.

[rahulctg]

Nothing with tab neither:(

FW-MHO-1> show maestro port 1/30/1 optic-info
Physical Port: 1/30/1
Vendor Name: CP-PROLABS
Serial Number: "REMOVED"
Part Number: NA
Check Point Part Number:"REMOVED"
Enforcement: Supported
Check Point SKU: CPAC-TR-40SR-QSFP-BIDI
Material ID: "REMOVED"
Product Type: 40GBASE-SR-BiDi
Speed: 40G
FW-MHO-1>
FW-MHO-1> show maestro port 1/30/1 optic-info
FW-MHO-1> show maestro port 1/30/1 optic-info
FW-MHO-1>

And yes correct, it is R81.20.

Thanks Danny, however, I need it to check optical Tx/Rx power per port. With the above scripts, I only get inventory.

[Danny · Accepted solution]

The third script runs mlxlink -d <device> -p <port> for each port.
If you dig a little deeper into the options of this command you should be able to find your solution.

[rahulctg]

Thanks Danny, I'm able to see the tx/rx power stats per port.

Just asking myself if it could be simpler to get tx/rx power from MHO, a key check during link troubleshooting?

[Danny]

Simpler than a one-liner?

[rahulctg]

Hahaha. I meant that I used multiple commands before you proposed mxlink one(for which I do say big thanks again) while the document proposes otherwise.

Hi,

mlxlink is described with examples in sk180812.
