Dell PowerConnect 6224 problem with SNMP
We have software in C++ (based on SNMP++) that configures an old Dell 5324 switch and has worked for ages. It fails to configure the 6224. The 6224 rejects an snmp set message to set VLAN membership for static untagged ports. I can reproduced the problem with the Net-SNMP command-line tools snmpset and snmpget. For example, with VLAN id 100, and setting the static untagged ports with 02 28 0F,
snmpset -v2c -c MyCommunity ipaddr:port 1.3.6.1.2.1.17.7.1.4.3.1.4.100 x "02 28 0F"
the Dell 6224 will not accept it, but it works fine for the 5324. The error is "commit failed." Any ideas?
No Events found!

Hi,
What version is the firmware of the switch? If you manually set the VLAN not through SNMP does it work?

The firmware version was 2.2.0.3, then I upgraded to 3.3.14.2. Yes, I can manually set it with CLI commands over the serial port.

I do not see 1.3.6.1.2.1.17.7.1.4.3.1.4.100 as a value on the 6224, nor do I see a replacement OID for it.

I do not see that either. I used a mib browser and searched for it. I also searched for vlan and went through all of the vlan related mibs for similar functionality.

The .100 is just a VLAN id I made up in place of the one we're using. The OID is 1.3.6.1.2.1.17.7.1.4.3.1.4.(VLAN id). Does the 6224 support 1.3.6.1.2.1.17.7.1.4.3.1.4 ?

So my 5324 runs a newer OS than my 6224, I thought the 6224 model came out later?

The 55xx run version 4 of the OS and the 62xx run version 3, so most likely it was added in the later OS version.

That would explain why it doesn't work! But it's supported in the 5324. Also, the 6224 accepts the .3 and .2 OIDs. That's weird that it doesn't accept the .4 OID.

Sorry I thought you had a 5524, not a 5324. The 5324 runs version 2, so I was wrong about that. I was able to find the OID in the 3.3.15.1 firmware, so you may want to try that. http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=VX5P0&fileId=3559244142&osCode=NAA&productCode=powerconnect-6224&languageCode=en&categoryId=NI

No. I installed 3.3.15.1, but same as before. I can read 1.3.6.1.2.1.17.7.1.4.3.1.4 but not write it. Is it possible that some CLI setup command can inadvertently lock out the permission to set Vlan static untagged ports over SNMP?
