[c-nsp] [External] Re: Question about 9410R interface naming

[Drew Weaver]

Yeah every time I evaluate a platform I now ask about this because on some Dell switches I manage when you change the interface from 10G to 25G it actually renames the interfaces and resets the configuration of the interface.

I understand that the ports are just broken out 100G ports but at the same time that's a terrible experience.

I suspect the reason for the weird abbreviation for "TwentyFive" and "TwoHundred" is because, on Cat9300, 2.5G is "TwoGigabitEthernet" - Tw

But hell, I just discovered on Cat9300 you can use Tw for both?!??!?!?!

MOR121c9300#show run int tw 1/0/1 | incl interface interface TwoGigabitEthernet1/0/1 MOR121c9300#show run int tw 1/1/1 | incl interface interface TwentyFiveGigE1/1/1
