Can you successfully SET other values on that box, using the same authentication values? (e.g. sysLocation.0) That will at least check whether the access control settings are sufficient to allow SET requests in general. > So I tried a different approach. > > We have an eServer running RHEL 5.4 with 2 n/w interfaces. > I have installed Net-SNMP 5.7 in it and run the snmpd and tried to set VLAN > on these interfaces using same command. The Net-SNMP agent doesn't support the Q-BRIDGE-MIB, as far as I know. So trying to SET elements of this MIB simply won't work. > 1.

So I think you ought to be using dot1qVlanStaticRowStatus.4 Where did the additional '0' come from? > 2.

It might well be that a bogus index value would give this error, while the correct index would work. Try it > 3.

If the agent doesn't include the code to support SET requests, then the fundamental requirement is for someone to sit down and write that code. Until this happens, the table will remain read-only (or not implemented) It's not a magic box - without the necessary MIB-specific code, the agent can't report or update anything.
