Help with VLANs, LAGs and Trunking on 5324
I have 4 5324 switches that are currently running with the native vlan1. I'm trying to create multiple vlans that get propagated across all switches. I have the three switches connecting back to the main switch each with a LAG. The LAGs are set in Trucking mode. I aslo have GVRP running on all switches.
1) The LAGs are configured as Trunking ports; but what should the ports that make up the LAGs be configured?
2) I can create a VLAN on the main switch and on one of the other switches, but the remaining switches dont see the VLAN unles I create it on the switch itself. Why is it not being propagated?
3) Should all LAGs be tagged with a (T) on all the VLANs?
4) When configuring the ports that are members of the VALN, should all ports also be tagged (T, G or U)?
Any help to clarify this setup would be apprecaited. I have a small image of the layout, I thought would be helpful but I dont see a way to include it in this post.
Thanks!

Example CLI...switch has ports 21&22 as one link aggregate, ports 23&24 as a second link aggregate, these aggregates connecting to similar aggregates on other switches. Three VLANs, 10,20&30, with port 1&2 in VLAN10, port 4&5 in VLAN 20 and port 7&8 in VLAN 30, these ports having non VLAN aware devices connected and are members of one VLAN only.
