C6509 slow servers

3 Servers are connected to a Cat 6509 with Intel and Compaq Gigabit NICs - they have poor performance (80kb/sec) and are loosing 10 percent of the pings - there is no traffic on the LAN.

The Cat 6509 was completely replaced - the problem ist the same.

The Server NICs work fine when connected to a 4912 or a BATM switch.

VLANs are configured, the MSFCs are not configured for L3-Switching.

Have anybody an idea what's the cause for the problems ?

Re: C6509 slow servers

Some more information would be needed to diagnose properly. Eg Backplane traffic, redundancy ( Have had probs with traffic flow with regards to redundant MSFC's and SUP).

Also are the ports set to auto negotiate, i have had problems in the past with Compaq NIC's also DO make sure FLOW control is configured correctly on both sides.
