2650, SNMP Security access violation
Still I receive "snmp: SNMP Security access violation" when I try to snmpwalk.
Firmware revision : H.08.53
What could be the problem? Thanks.

Re: 2650, SNMP Security access violation
Do ALL the community strings in your SNMPWalk utility match ALL the strings set in the switch? Are you sure they match? Check again.
Are you sure you set the authorized managers correctly?
What utility are you using to walk the MIBs?
Have you tried another utility to query?

Re: 2650, SNMP Security access violation
the problem is that I have another 2650, configured absolutely the same way (IP address is the only different thing). The have the same firmware.
here are the snmp-relevant config lines:
snmp-server contact "me@my.com"
snmp-server location "my_location"
snmp-server community "my" Operator
and there are no ip authorized managers.
this config works on one switch, and does not on the other.
what could I do?
(warm and cold reboots already tried).

If this is necessary, I will give ssh access to the switch!

Re: 2650, SNMP Security access violation
Maybe you can try:
snmp-server community my manager restricted
for read access only. Or for read/write:
snmp-server community my manager unrestricted
Hope this helps.

Re: 2650, SNMP Security access violation
again, I have two switched with the same firmware and the same configuration. when I snmpwalk one switch -- it is ok, when the second - it is complainging about snmp security access violation. I've even tried snmpv3 -- the same result, though all the parameters are ok.

Re: 2650, SNMP Security access violation
Do a showtech on both switches and compare them in detail.

Re: 2650, SNMP Security access violation
on the first (snmp-good) switch:
vlan 1
vlan 3
vlan 2
vlan 5
vlan 4
vlan 10
on the second (snmp-bad) switch:
vlan 1
vlan 2
vlan 4
vlan 5
vlan 10
vlan 3
ALL the rest of configuration is COMPLETELY the same.
so, up to me, there is a bug in firmware.
the testing I've done: - I've taken the snmp-good switch and configured vlans on it in the order they are configured on the snmp-bad switch. ANd, it starts to complain about snmp security violation.
again, i've checked that ALL the configuration is the same, the difference is the order I configure vlans.
Hope, this information is helpful.
PS: by the way, why vlans appear in the order they are created, and not in the numbering order?
