SNMP Oid Information Lookup

[Brian Seppanen]

Hi:

I'm trying to find out more information on a specific oid that I've been
given for signal to noise.
The OID is .1.3.6.1.2.1.10.127.1.1.4.1 and a -OS indicates its from
SNMPv2-SMI mib. Now I need to find out the type of measurement, the
intervals. Basically anything about what these values return so that I
can insure that I'm treating the data properly.

Anyone have any ideas on where I could find that data? This oid is used
to measure the s/n ratio for cable interfaces off of cisco routers.
SNMPv2-SMI is a dead end as far as I can tell, but then again I don't
understand mibs at all.

I'd appreciate any help.

Thanks,
Brian Seppanen

If you have sufficient mibs installed, you will get

$ snmptranslate -Td -OS -mALL .1.3.6.1.2.1.10.127.1.1.4.1
.1.3.6.1.2.1.10.127.1.1.4.1
