MIB Support

Hello Gentlement,

I have this little doubt about the MIB support on Cisco Devices.

When I enter the command:

#show snmp mib

It gives me back a list with the MIBs supported by my IOS.

But when I go to a linux machine (for example) and run a snmpwalk <gateway IP> -c <community> -v 2c <oid>

it dosnt give me some mibs that was listed on the command.

I already double checked the community and he actually responds for a lot of snmp requests.

Do you guys have any ideia about why some mibs listed in the command are answered as Invalid OID ?

Re: MIB Support

Have you configured the dial-control-mib history size on this device. For example:

dial-control-mib max-size 100

dial-control-mib retain-timer 10

It may be that you do not have any call history to poll.

Re: MIB Support

The show snmp mib commands provides a list of objects, not MIBs. Some of those objects require that you configure the underlying protocol or technology before they can be polled. Exactly what objects were you trying to poll?

Re: MIB Support

I have a AS5350 and I was trying to get the callHistoryDisconnectCause (1.3.6.1.2.1.10.21.1.4.3.1.6).

When I run the snmpwalk it returns me:

No Such Instance currently exists at this OID

Thanks for the help.
