Nexus N2K-C2248TP-1GE with 10Mb/s

[Toni Rittger]

Hello,

according to the N2K-C2248TP-1GE Datasheet, the 2248TP has 48x 100/1000 interfaces. With NX-OS 7.0(2)N1(1) on a N5548UP, I am able to configure "speed 10" and it is working, "show int ethxxx/0/xxx capabilites" confirms speed 10/100/1000 and auto. Another Nexus with NX-OS 6.0(2) the command "speed 10" isn't available. "show int ethxxx/0/xxx capabilites" confirms speed 100/1000 and auto.

Does someone know with which NX-OS version "speed 10" has been introduced? Or is this some special kind of bug/feature request implementation without an release note entry? I only found a downgrade bug related with speed 10. I just want to make sure that the commend will still be available with the next upgrade e.g. to 7.2(0)N1(1).

Regards,

Toni

Toni,

Agree with you.
Nexus7010# show int e101/1/37 capabilities
Ethernet101/1/37
  Model:                 N2K-C2248TP-1GE
  Type (Non SFP):        10/100/1000BaseT
  Speed:                 100,1000,auto  >>>>>>> 10 speed option not available.

 It does look like on 7.x code we support 10mb (speed 10)
command:

I believe you are refering to the following bug:-

Inayath,

you're right with the bug. I didn't find any futher information related to "speed 10" for Nexus 2248TP excpect that bug. Curious, that the feature didn't get a release note entry. For the 100 Mbit for the Nexus 23xx, I found one.

I hope Cisco will not change this behavior without notification. Would be annoying if our two 10Mbit-sensors would become unreachable after a software upgrade.

Regards,

Toni
