Performance? I think is should work, but performance may be poor. Currently, vlan_input() finds the correct vlan by searching the list of all vlans until it finds the correct one. For that many vlans, it might be necessicary to modify the code to use some form of balanced tree instead of a simple list. This should be fairly straight forward to fix. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
