Hi Drew,
ipNetToMediaIfIndex is also deprecated.
RFC1213-MIB defines atIfIndex thusly:
/ "The interface on which this entry's equivalence//
// is effective. The interface identified by a //
// particular value of this index is //*the same *//
//* interface as identified by the same value of*//
//* ifIndex*//."//
/
ifIndex is defined in IF-MIB (RFC 2863) as .1.3.6.1.2.1.2.2.1.1,
possible a better answer than you came up with?
To answer ytour question, I used a tool I wrote that parses
MIBs and loads them into a SQL database. Here's the query
I used to find atIfIndex:
# select mib,snmpoid,snmpsymb,status,description from flatsnmpoidmap
where snmpsymb = 'atIfIndex' and mib = 'RFC1213-MIB';
mib snmpoid snmpsymb status description
─────────── ──────────────────── ───────── ──────────
───────────────────────────────────────────────────────────
RFC1213-MIB .1.3.6.1.2.1.3.1.1.1 atIfIndex Deprecated The interface on
which this entry's equivalence is ↵
effective. ↵
The interface
identified by a particular value of ↵
this index is the
same interface as identified by the same ↵
value of
ifIndex. ↵
Using the hint of "ifIndex" in the description,
I queried for that:
# select mib,snmpoid,snmpsymb,status,description from flatsnmpoidmap
where snmpsymb = 'ifIndex';
mib snmpoid snmpsymb status
description
────── ──────────────────── ──────── ───────
───────────────────────────────────────────────────────────
IF-MIB .1.3.6.1.2.1.2.2.1.1 ifIndex Current A unique value, greater
than zero, for each interface. ↵
It
is ↵
recommended that values
are assigned contiguously starting ↵
from
1. ↵
The value for each
interface sub-layer must remain ↵
constant at least from one
re-initialization of the entity'↵
s network management
system to the next re- initialization.↵
So ".1.3.6.1.2.1.2.2.1.1".
I plan to release the tool (Netlens) into the public domain soon, with a
public-
accessible web interface. Presently it contains 65 MIB's and 2799 rows.
Hope that helps,

Hi All,
It seems like ipNetToMediaIfIndex is the replacement for that other OID I
mentioned so no problem but still it would be great if anyone knows of a tool
or site that handles replacements.
<snip>
This question I suppose is not specific to Cisco except that some of the OIDs I
need don't exist in NXOS (but they do in other Cisco OS).
In general does anyone know of a tool or a website or something that will take
an obsolete OID and suggest a working equivalent?
Specifically, I found this OID to be useful RFC1213-MIB::atIfIndex
(1.3.6.1.2.1.3.1.1 in the past and I am looking for the modern alternative.

Does anyone know specifically if RFC1213-MIB has been replaced or if there is
any other way to get the same information (via SNMP)?
