I'm not completely clear on what is being attempted here, but if the goal is just to have a portchannel with 802.1q subinterfaces, you don't configure the subinterfaces on the physical interface, just the port-channel. So in the config, the following interfaces should exist: Gi0/0/3 Gi0/0/4 Po1 Po1.1 Po1.99 -- Brett _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
