Im using a WS-C3550-24-FX-SMI Switch with MTRJ connections to connect Workstations. I have this switch connected to a Cisco WS-C2912MF-XL Switch GBIC SX TO GBIC SX. I have connectivity to the 3550 switch. From the 3550 switch, I can ping throughout my Network. I can ping from my Servers to the 3550 switch. However, here is where it get hairy. I have six workstations connected to this 3550 switch, and all connections reflect a Green Link Light on the Switch, however, only one of these workstations has full connectivty throughout my network, and the other 5 DO NOT. I cannot ping these 5 workstations from the 3550 Switch, and of course, I cannot ping anywhere on the network from these 5 workstations. ALL Workstations are using the same NIC (Allied Telesyn AT-2700FX PCI 100MB Fiber Ethernet Adapter), and they are ALL Set to FULL Duplex, as well as the Ports on the 3550 Switch are set to FULL Duplex. Now, when I run DEBUG ALL on the 3550 Switch, Im getting the following on all Ports, Including the GigabitEthernet Ports - "FEC: get-fechannel: port (FastEthernet 0/1) not part of FECHANNEL".
I have tried everything that I know. Anyone have any Ideas/Suggestions. Thanks in advance...
