I am trying to configure vlans on a netgear GS752TSX from the Linux command line with netsnmp. I have created vlan 99 on the web interface now want to control the pvid settings, egress and tagging. I have identified these as the MIBs I need to change:
dot1qPvid.<port>
dot1qVlanStaticEgressPorts.99
dot1qVlanStaticUntaggedPorts.99
Pvid works as I expect:
$ snmpset -r 1 -t 20 -v 2c -c private <switch> dot1qPvid.17 u 99
Q-BRIDGE-MIB::dot1qPvid.17 = Gauge32: 99
$ snmpget -r 1 -t 20 -v 2c -c private <switch> dot1qPvid.17
Q-BRIDGE-MIB::dot1qPvid.17 = Gauge32: 99
and so do the egress ports:
$ snmpset -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticEgressPorts.99 x 'ff ff ff ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00'
Q-BRIDGE-MIB::dot1qVlanStaticEgressPorts.99 = Hex-STRING: FF FF FF FF FF FF 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00
$ snmpget -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticEgressPorts.99
Q-BRIDGE-MIB::dot1qVlanStaticEgressPorts.99 = Hex-STRING: FF FF FF FF FF FF 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00
But untagging the ports doesn't seem to remember my setting:
$ snmpset -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticUntaggedPorts.99 x 'ff ff ff ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00'
Q-BRIDGE-MIB::dot1qVlanStaticUntaggedPorts.99 = Hex-STRING: FF FF FF FF FF FF 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00
$ snmpget -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticUntaggedPorts.99
Q-BRIDGE-MIB::dot1qVlanStaticUntaggedPorts.99 = Hex-STRING: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00
I have tried netsnmp 5.4.1 and 5.7.2.
Is there something I'm doing wrong?
