Issue trunking VLANs between AdTran Netvanta 1234 Layer 2 switch and Cisco Small Business SG300-52P switch
Posted on 2014-04-06
I have an existing, older layer 2 AdTran Netvanta 1234 switch that I am trying to trunk into a new Cisco Small Business SG300-52P switch.
It should be a standard operation as the setup is not very complicated:
The EDGE network is the ISP...we have it setup this way because a few devices need to be plugged into the edge with public IP addresses.
I am trying to trunk this setup to a Cisco Small Business SG300-52P switch. No matter what I do, when I trunk, things will not work correctly between the switches.
The SG300-52P switch is setup in Layer-3 mode, and I am trying to get the switch to do routing between the VLAN's. Anything plugged into the Cisco switch works exactly as expected, but anything in the AdTran does not work, and the trunks don't seem to line up.
- I've created the same VLAN's in the Cisco
- I've named them the same as well (although this shouldn't matter)
- I'm uplinking with a single GIG port setup as a trunk
- I've set the allowed VLAN's to ALL
On Cisco Catalyst switches, I usually have to specify the trunk protocol (802.1q) but on the SG300-52P switch, this command is not an option, and the GUI does not seem to have a corresponding option as well. There is the standard PVID (Native VLAN), trunk vs access, and trunk membership...everything seems to be lined up correctly with the trunk port as a member of ALL VLAN's, and I've tried with and without a NATIVE VLAN set (native VLAN set to DATA when it was set).
Can anyone give any insight into this issue?
Note: The AdTran later 2 DOES have a VLAN setup for each VLAN as well, and there is no VLAN setup that does not exist in both switches.
