I have a 6509 switch with 7 48 port gig blades completely full and am wondering if it is being overloaded. There are about 40 servers running gig and the rest is workstations/ip phones at 100 meg. All are on a single VLAN.
What I am seeing when I run a capture transferring a 60 meg file, it only takes a second or two between servers but I see about 900 duplicate Ack's with about 100 frozen windows. I've tested on various servers and see somewhat the same thing with some having a lot of retransmissions.
This does not seem normal but wanted to ask others what they think. I am wondering if the broadcast domain is not the cause of the problem. If this is not normal, how can I best determine what the tru problem is?
