Thanks.
I took a look at the code and tried playing around a little with the OIDs that you are using for VLANs on standard boxes, I'm still getting inconsistentValue errors though, like this:

I tried hex string just to see if I still got wrongType.
The OIDs I've found on the switch are very.. obscure, it would seem.
They look like this:

The second one is the one that is supposed to be 'correct' and I'm just trying to set the OID to the same as the value before. There are a couple of other private OIDs connected to VLANs, one that is per VLAN with a hex string that you set to which ports are allowed which is only six hex groups long.

Do you have any idea what I might be doing wrong?

Hello,

Hello, again



Yes, that is the primary thing. But also for identifying which VLAN is on which port and what VLANs are available on the status page for the switch. I'm not sure that is the PortAdmin module?

No, that information is not coming from PortAdmin and I have not written that code
and I am afraid I cannot help You much with that particular code.  Sorry.

Still I would advice You to take a look at the snmp-code for PortAdmin.  I think it will
give You some ideas how You could do this.

You will find the code in:  python/nav/portadmin/snmputils.py



I am however as stated having some problems with writing to the VLAN OIDs as stated, I'm getting inconsistentValue returned no matter what I try, it feels like. I'm not sure what I'm doing wrong and if someone seasoned with SNMP could help me out with how to track down the error, that would be greatly appreciated!

I am not quite sure if I understand,- but I guess You are talking about the
confusion regarding what value-type to use when writing back to the
equipment.  Some take an unsigned integer and some don't. A VLAN is
a positive integer and in most cases you would use an unsigned integer.
If You take a look at the code, You will see that we in some cases try both.

If You also want to change VLAN on a port You must also remember to
remove the port from the VLAN You are moving away from.

Is this of any help to You?

Sincerely

Trond.
