Question about 9410R interface naming
Hi,

I have a quirky question about the 9410's Interface naming/numbering.

These switches appear to support 1G 2.5G, 5G and 10G interfaces.

Do the names of the interfaces change depending on the speed?

Is it ethernet1/1/1 no matter what? Or does it change to GigabitEthernet1/1/1 or TenGigabitEthernet1/1/1 depending on how it's configured?

If anyone knows I would appreciate it.

Thanks,
-Drew

Good Morning Drew,

They are TenGigabitethernet Interfaces:

Port Name Status Vlan Duplex Speed Type
Te10/0/44 connected xxx a-full a-1000 100/1000/2.5G/5G/10GBaseTX

Have a good day,

Off topic slightly, I have seen these recently....(xr7)

802.3bz

Options for speeds beyond 1Gbps but maybe you can't (cheaply easily
quickly) rip and replace all your building/house cabling to make the
leap to 10GbE. You can do 2.5Gbase-T over Cat5e, for example.

Although you can do 10Gbase-T over Cat5e for xx number of small meters
as well (I think Arista used to say 20m in general, but not spec'd,
and nothing guaranteed). I've done around 12m runs of cat5e on
10Gbase-T without issues, but would usually replace with cat6 in general.
But yeah, inwall cabling would generally be too long for that.

The NBASE-T speeds are popular in WiFi AP as the speeds one could get under ideal
circumstances started pushing over 1G limits.

if there were a fundamental difference between these interface types,
the naming differentiation might be useful, but it's all ethernet.
Fortunately, other vendors mostly steered clear of this approach.

Re: [External] Re: Question about 9410R interface naming [ In reply to ]
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

The inclusion of POE with NBASE-T also helps on the AP use case.

Re: [External] Re: Question about 9410R interface naming [ In reply to ]
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.
