Re: Command to check SFPs - Page 2

Navneet_singh · ‎02-07-2011

Hi All,

What command can we use to check the type of SFP inserted in a switch or Router? I needed to check if the blade in my 4500 switch is populated with any SFPs? Will the command be applicable for other series of Catalyst switches as well?

Appreciate your help.

Cheers

Navneet

Transmit power is typically good when it is in the 6 dB range between -1 and -7 dBm. Receive power is normally expected between - 1 and -9.9 dBm.

Hi All,

On Switch we can check the SFPs Model/Serial number by the well know commands like "show inventory" or also we can get some details about SFPs with the help of command "show interface status" and there are multiple help article on internet they can help us to get the details of Switch SFPs.

However for Router like Cisco ASR1001-X when we need to check the SFPs details then we also get confuse with "subslot and transceiver"

So to check the details information about port and SFPs you can use the below commands. (here it's output of ASR1001-X) Router

Deepak_Kumar#show hw-module interface Gi0/0/0 transceiver idprom brief

For different Router like ASR-1001 this command can be used: The example show the output for the 6th transceiver in Modul 0/0.
