Just swapped a 2950 10/100 switch with a 2960 Gigabit switch. Our servers on the switch are Dell Poweredge (win2003) running broadcomm gigabit nics. We have 2 servers that are having an issue now....when pinging from another server on the same switch (or anywhere else on the network), the 1st ping will time out, then the rest will go through fine. Ping again, all respond ok. Wait about 5 or 6 minutes...and the 1st will time out again. The only thing that has changed is the switch. Ports were configured using the "desktop" setting on smartports and the config is below...all ports are the same.
interface GigabitEthernet0/2 switchport mode access switchport port-security switchport port-security aging time 2 switchport port-security violation restrict switchport port-security aging type inactivity macro description cisco-desktop spanning-tree portfast spanning-tree bpduguard enable
I made sure the power off when not in use option was unchecked for NIC and have also updated the NIC drivers. My understanding is the if it was a portfast issue it would be a 30 second delay...this is more like5 seconds. Any ideas on why with the gigabit switch change this is occuring? Am I not supposed to use the "desktop" setting for servers? Again, it's only on 2 servers (nothing in the event logs).
