E-mails delaying with CAT3750 Stack connection.

Hi all,

I have 4 Microsoft Exchange servers connected to CAT3750 stack. I noticed a delay in getting e-mail by having a look at the queues on the servers. But when I connected all the servers to a small hub, I don't see any queues and there is no delay in getting e-mails. The hub is connected to a port on the same CAT3750 stack.

All the four servers are in the same VLAN.

The switch is running the following IOS Version:

c3750-ipservicesk9-mz.122-25.SEE.

Can someone please advise me what to do to resolve this issue.

Thanks.

Shoaib.

Are those four serves attached to the same switch?

How are the switched stacked, with cascade cable or UTP?

Can you post configuration details?

Hi Leon,

Yes, the four servers were attached to the same switch.

The switches are stacked with backbone.

The configuration is attached.

Thanks,

Shoaib.
