Intel Pro/100+ NIC and 6148 Modules

I have recently swapped out a Catalyst 5500 and replaced it with a Catalyst 6509. I have a Xerox Fiery Server (running NT 4.0 Workstation) which is front-ending a Xerox high-speed printer/copier. The Fiery server has an Intel Pro/100+ NIC installed on it's motherboard. I am running the latest driver for that NIC, ver. 6.4 and CatOS 7.4(3) on the 6500. I want to run the server at 100/full. The server ran fine at 100/full on the 5500.

When I attach the server connection to a port on a 6148 module inside of the 6509, I can not get the device to coonect at 100/full. I have hard coded 100/full on both sides and no luck - no link light on the server or switch port, port staus shows "not connected". Tried auto/auto and 100/half on both sides - same results. Tried 10/full and 10/half on both sides and the server connects and port status shows connected. I really need 100/full though.

If I configure the server NIC for 100/full, take the server connection off of the 6509 switch port and attach it to a 3COM or NetGear 10/100 switch, then connect the 3COM or NetGear 10/100 switch to the 6509 switch port, I am able to have the server connect at 100/full. This is my workaround, but not the desired scenario.

I have a second Fiery server w/the same NIC attached to a 6509 w/6148 modules and I am experiencing the same problem.

I have replaced the 6148 module, moved the connection to another switch port, tried a 6348 and a 6248 module instead of the 6148 module. I have attached other non-Xerox devices and a laptop to this same 6509 switch port and have no problem connecting and running at 100/full. I even went back and connected the server directly to a 5500 w/a 5224 module and had no problem running this box at 100/full again.

I have turned off in-line power and flow-control settings on the switch port and attempted to adjust jitter tolerance, no luck.

Anyone have any ideas or experience a similar issue?

Re: Intel Pro/100+ NIC and 6148 Modules


I could be some problem with power management on the nic or spanning tree issues.

spanning-tree portfast on the port should disable the frames.

Disable the feature power mgmt on the network adapter (in the control panel).
