SNMP Walk Issue from LMS

Hello Experts,

I tried SNMP walk from LMS for below OIDS  but getting the error as attached..

MIB Name :- c2900PortDuplexState

OID's : 1.3.6.1.4.1.9.9.87.1.4.1.1.31
1.3.6.1.4.1.9.9.87.1.4.1.1.32

But while i do with OID 1.3.6.1.4.1.9.5.1.4.1.1.10 its showing the results.

My requirement is the pull the current negotiated Duplex status of interfaces, but with the OID 1.3.6.1.4.1.9.5.1.4.1.1.10 its only showing the configured values [ Auto , full or Half] not the negotiated duplex status if the port is in auto state. Please suggest.

Regards

Deben

Hi Deben,

here's a small list of OIDs for duplex for the Catalyst platforms I know and use:

1) 2900XL, 3500XL, 2900LRE, etc.: c2900PortDuplexState, c2900PortDuplexStatus

2) 2960, 3550, 3560, 3750, 4000, 6500: CISCO-STACK-MIB::portDuplex

3) 4500, 4900: EtherLike-MIB::dot3StatsDuplexStatus

For some reason I don't have access to the Object Navigator at the moment, so I can't provide the details.

I remember that one or more OIDs only work for active interfaces ("up"), just give it a try.

Hope that helps

Rolf

using ifMauAutoNegAdvertisedBits. In either
case, the currently operating duplex mode is
reflected both in this object and in ifMauType.

Note that this object provides redundant

instance, it allows a management application to
determine the duplex status of an interface
without having to know every possible value of
ifMauType. This was felt to be sufficiently
valuable to justify the redundancy."
