Here is the strangest thing I have ever seen.
Working network, with Cat4006 at the core. Bringing in vmware, so bought 3750G-48-TS switch. Setup trunking from 3750 Gi1/0/48 to port 5/22 on 4006.
Ping works. Telnet works (with some commands pausing on the 3750). Everything else, does not work.
Unable to open 3750 web gui, just hangs.
We moved our servers to the 3750, and network applications were horribly slow, except if the apps were being tested from plugged into the same switch. Again all icmp traffic worked.
Moving the servers back to their old HP switch, everything works back to normal.
Any help would be appreciated.
I am attaching the trunking portions of each config below.
The 4006 is the root switch in the spanning-tree right now.
set vlan 2 5/22-24
clear trunk 5/22 1,3,5-1005,1025-4094
set trunk 5/22 on dot1q 2,4
switchport trunk encapsulation dot1q
switchport trunk native vlan 2
switchport trunk allowed vlan 2,4
switchport mode trunk
Now these switches are relatively far apart, running Gig over normal Cat5 (not Cat5e), not sure if cabling could be a problem or not.
