LAG Configuration-multiple switch

Question

-5 - 6224 Switches with NO ROUTING enabled

-1 of the 5 switches is acting as a LAG switch in that I've got (2) port LAGS coming from the other 4 switches into the single 6224.

-The single switch containing all of the other switch LAG's is configured with (LAG CHANNELS 1-4 respectively).

-All non-LAG ports are configured as untagged members of VLAN 10 and the LAG CHannels are configured in GENERAL VLAN ADD 10 TAGGED throughout.

When attempting to bring multiple switch ports configured in a LAG into a single switch, do I need to keep the port-channel numbers seperate or should I be able to create a single port-channel for all of VLAN 10 between all switches? I'm getting some intermittent results when setting up the lab of switches and i'm not yet comfortable with where the config is going.

Hi jimbennin, Each switch LAG should be its own LAG channel. So you should have 4 different LAG channels. LAG is basically creating a virtual port out of multiple ports.

Thank you,  I'm not sure why I didn't think of this before.  I'd had each switch to switch LAG segregated by LAG# on the concentrator,  just forgot to re-add the allowed VLANs after i created them.  Your answer triggered this in my mind.  Again - Thank you
