Update... Updating the Cisco switches to the latest IOS, locking the protocol as LACP, and setting both the switch and Solaris system to active LACP mode has at least improved connectivity to the point where some systems are now reachable over the trunked VLANs on the aggregated ports.
Here's the Twilight Zone observation: for two hosts (one Sun, one linux box) that cannot ping each other over the connection, running snoop on the Sun box enabling the connection between the two hosts! As soon as snoop is closed, the connection jams again. Both hosts have arp cache entries for each other's mac addresses before running snoop. Another bizarre "trick" that seems to un-jam the connection is to run a constant ping and then unhook and reconnect one of the network cables. The cables and ports were all checked and appear fine. I note this posting on comp.sys.unix that seems to describe a similar scenario: http://groups.google.com/group/comp.unix.solaris/browse_thread/thread/b0b0c7bf3c7a79e9/f5734aa1b1a6f7f4?lnk=gst&q=aggr&rnum=1#f5734aa1b1a6f7f4 Any ideas?
