I have a 300 series switch with VLAN1 untagged, VLAN 15,5,100 tagged. I want say ports 1-12 to use one uplink/trunk and 13-24 to use another uplink. All ports should have the same default VLAN1 and be tagged for 5,15,100. I'm trying to ease the load on two wireless uplinks(one is a Cisco 1242AG and the other is a UBNT PowerBridge.) I don't want to add another switch. Is this possible?
Model:
SF 300-24P

Hello Derek,
Thank you for using the community forum.
It looks like you would be creating a loop. This would cause Spanning-Tree to kick in and prevent the loop by shutting down one of the Trunk ports. You can load balance at layer 2 but it requires balancing by vlan. So you would need to send 1,5 across one trunk and 15, 100 across the other. Would this be a posibility?

Can you provide a topology of your intended design?

Bad diagram. Should be matching pairs of 1242AG and UBNT bridges.
Campus --> switch --> 1242 root --> 1242 non-root --> 300 switch --> phones and computers
The UBNT link is coming from the same switch the 1242 root-bridge is connected to. I don't want a loop though.

Basically I want switch 2 and 4 to be one switch but act as 2.

Sometimes I really miss the obvious thing. Of course, yes, trunk the VLANs separately. That makes sense.
Separate trunks for the traffic would cut down on congestion.
