channel-g...

i used a channel group between the 2 dsw's with an ip address configured directly on each end, as in the topology... 2 xover cables that had been previously configured for trunking... note the no switchport command and the lack of pagp or lacp negotiation...  a case can be made for negotiation because it will prevent inadvertently causing an errdisable to occur...  if you are certain both ports are configured the same, negotiation is really academic, for the purists of the bunch... lacp may come in handy for connecting to servers that are lacp capable...

Port-channel1 is up, line protocol is up (connected)
  Hardware is EtherChannel, address is 000f.8ffe.0980 (bia 000f.8ffe.0980)
  Internet address is 10.1.4.13/30


you get the idea...
