The networked is depicted in the diagram. The 172 network is a SAN. I'd like to use 4 ports from the Cisco 3020 to the HP 2810 as a port-channel so as to take advantage of more bandwidth. So far I have not has luck getting the channel to come up or stay up. I plugged 4 cables from Cisco to HP, made sure they were in the correct vlan, setup the ports on the HP switch into a trunk:
Trunk 1-4 trk1 trunk lacp
On cisco setup a port channel, added the ports to it and then ran this on the ports:
Channel-group 1 mode passive
I thought that would make the HP 2810 setup a port trunk with the cisco but it generally brought down the network, caused flapping errors on the cisco and caused the ports to go up and down.
