I want to create a tagged link to my router's subinterfaces. Do I use link aggregation for this? does LAG automatically carry all switch traffic? or does the port(s) need to be included in each VLAN? and each vlan need to have the LAG as a member?
I Have the same issue , i would like to setup an 802.1q trunk between swtiches and carry some vlans trough but the documentation talks about lag but not 802.1q trunking from a port to an other switch
we too also having the same issue. I've setup LAG port 1 which include 1/1 and 1/2 and they are connected to a Foundry L3 switches using LACP. That seems to be OK. But I'm also having issue setting up the LAG port as 802.1q tag port so that vlan traffic from two different vlans can be "routed" thru. Anyone have any idea how the vlan tagging works? greatly appreciate your suggestion...
To create a 802.1q trunk port, you need to manually include the trunk port as a "tagged" member of all the VLANs you want to trunk to the other switch. If your trunk port is a LAG, after you created the LAG, make the LAG interface a "tagged" member of all the VLANs you want to trunk to the other switch.
This is my configurati0n, I think I´m doing what Lap say´s but, it doesn´t work, can some body helpme ? (NOTE: I made same configuration in booth switches, same ports, same vlan id etc.)

+++++ Here if i plug 2 laptops with same subnet address in the vlan1, the echo works fine, I mean i can ping each laptop if they´re in vlan1, but if i change booth laptops to vlan2 i can´t ping none +++++ What am I doing wrong???

+++ Here, when I plug laptop1 in switch1-vlan1 and laptop2 in switch2-vlan1 the ping response is OK, but if i connect laptops in vlan2.... :(:confused:
fyi peeps, trunk ports are used to transfer vlan data from one switch to another switch or trunk capable devices such as wireless APs.
therefore, if Switch A port 1 is set to trunk for Vlan 3.. and port 20 is set to Untagged or otherwise known to set to VLAN 3, then if port 1 of switch A is connected to port 1 of Switch B that is set with the same config of Vlan 3 (tagged or trunk), then VLAN 3 data will be transfered from Switch A to Switch B.
so a PC connected to port 20 in SwitchA, can deliver data to another PC connected to port..24 in SwitchB if the port 24 in switch B is configured as Untagged VLAN3.
