network topology

L3Switch<->2960<->Alteon

         |
     Real Server1
     Real Server2

The topology has a 2 real servers and the alteon sitting off the 2960 switch. The 2960 is connected to a L3 switch which provides connectivity outside the subnet. These servers are service the LAN and not the public.

The problem arises when i try to connect to the VIP the browser hangs and I lose connection to the Alteon as well as all the other servers hanging off the 2960 switch. once i shut down the 2960 interface connected to the alteon everything comes back up again.

Can someone take a look at the config and advise

2960 port connecting to LB config

Switch port config looks fine; must be something with the Alteon –  Jason Seemann Sep 21 '11 at 12:43

Further to this when the load balancer is live on the network now. The real IP's have not been assigned to any devices.

If further info is needed let me know
