ACLs slowing traffic.
I have some simple ACLs that are applied to each Vlan (except default) that allow a Vlan to communicate to the other local Vlans. This blocks all other traffic so the only routes from each vlan have to go through the proxy.
The default gateway of each vlan is the IP (X.X.X.1) which is also allocated to a subnet.
With the ACLs on, on non-default vlan I get random ping rates when pinging the default gateway on each vlan (DG=IP of vlan manually set on core switch): 1ms,1ms,756ms,1222ms,1ms,380ms
ACLs off and its fine: 1ms,1ms,1ms etc .... however this, in theory, gets round the proxy.
Our switch is a 5308xl w/11.09 FW.
CPU util is under 5%

What network speed is the proxy working at? 100Mbps or 1000Mbps?

Cheers Michael. Its on an auto-1000 port. However I dont have access to the LEA proxy for its connection info at the other end.

If it's LA managed, then maybe you should contact them for more information? Something definitely isn't right as ACLs shouldn't create the problems you're describing.

I just dont see how the internet is relevent. If I disconnect the network cable to the proxy, pinging the Vlan DG from a vlan'd IP is still slow... remove acl and its fine. I'm not going via the net.... it just so happens that the acls are for stopping net access without a proxy address.

Are you using the latest firmware for the switch?
