Why is ASR1000 series router showing 100/42 port

[rawatrajesh]

I was running through my ASR-1000 series router configuration kept at remote data-center and observe that i see 100/0/42 whereas multiple sub-interface are created against port number 42.

When I check my physical ports i could not find port number 42.

Moreover when i verified the data-sheet of ASR-1000, it shows that modules available support maximum of 40 ports.

Then how is that i am getting port number 42 on my router? Can someone please help identifying.

Hi 

Could you please share the show platform output and running configuration in a file.

The platform that you are running is ASR9k and not ASR1k. Also, the ports that you are seeing are satellite links. the reason that you are seeing 100/0/0/42 and other interfaces is because of below configuration:

nv
satellite 100
type asr9000v
description CHCGILTCHU6_100
!
You can refer to the below command guide for reference:

Hope this answers your question.

Thanks Vinit for the clarification.

How do I find which physical port is it?

Please omit my earlier question. I kind-off found out the physical port in the configuration against which the satellite port is mapped.

Thanks for your help.
