I looked through all the MIBs supported on Nexus 7K and could not find an object that would tell me if an Ethernet interface is configured to allow auto-negotiation or not.
So I did a test: on the NX-OS command line, I did an snmpwalk starting from "iso", saved the result to file-1.
Then I configured one interface, say Eth2/32, from speed "auto" to 10G. Ran the above command again and saved the result to file-2.
After that, I extracted all the lines in the two files about interface 2/32 using its ifIndex, diff'ed the results and found no difference except for in/out traffic counters.
Does this mean that NX-OS has no SNMP support for stuff like that?
Have I missed something in my experiement?
Is this an indication of Cisco's moving from SNMP to XML based device management?
Details: I run SNMP v2c. The Nexus box is:
BIOS: version 3.22.0
kickstart: version 5.1(4)
system: version 5.1(4)
BIOS compile time: 02/20/10
kickstart image file is: bootflash:///n7000-s1-kickstart.5.1.4.bin
kickstart compile time: 12/25/2020 12:00:00 [06/28/2011 23:28:40]

Thanks and regards,
Yeah, but those didn't give me “a-half” or “a-full” like one would get on the IOS CLI, only “half, full, disagree, or auto”. IIRC, the cat6k's I dealt with didn't support MAU-MIB, nor a third candidate MIB I came across--ETHERLIKE-MIB.
