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 ?
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.
