I have a problem with a bladecenter e and the network connectivity.
there are 6 blades (5x hs22 - windows 2008 r2 and 1x hs21 - vmware), 2 nortel switches on bladecenter and 2 hp switches for the clients.
nortel switch 1 -> 4 cables to hp switch 1 (using lacp)
nortel switch 2 -> 4 cables to hp swich 2 (using lacp)
ports for blade servers are not configured to use lacp or trunk
blade servers nic teaming is active. using basp with lacp (active/passiv)
now if a blade server pings another, i got timeouts. 20 pings, 1 timeout.
if all nics of the blade servers are active on the same nortel switch, there are no problems. if one nic has changed the switch, i got timeouts.
i read the redbook and i think i have done all necessary steps..
what am I doing wrong?
