Nexus - NX-OS IfDescr interface FC?

[vgaraboa]

Hi.

Can I using snmp (snmpwalk) to test interfaces Fibre Channel (fc1/10) on NX-OS (7.0.2)?

I can view the IfIndex using 'show interfaces snmp-index', but if I use snmp and snmpwalk I can't locate any info about these interfaces.

Thanks in advance.

Vgaraboa.

Hi Jim.

Thanks for your answer. I'm using just what you say, but when I try to find any info of our FCx/x interfaces, nothing appears.

I tried to do a total smwbulk query to NX, and same result, I could not see nothing of these interfaces.

Regards,

Victor.

Hi Victor,

Sounds like you might be hitting this bug, CSCup75270 -  FC interfaces are not listed in IF-MIB snmp walk. 

Link to it on Cisco Online:

https://tools.cisco.com/bugsearch/bug/CSCup75270

If this doesn't match, can you give me a little more information.

What Nexus product are you using ( model number )?

What version of firmware is running on the switch ( show ver )?

What interfaces are configured to be native Fibre Channel?

Thanks,

Jim

Hi Jim.

You're right, our Nexus N5K-C5548UP has the OS version 7.0(2)N1(1).

Thanks for the bug link.

Víctor.
