Event log full of high collision or drop rate event and loss link active on port number

[IT-A]

hello,

we have a lot of  "loss of link on port number" events and a couple of "high collision or drop rate" events in our event log. our network uses and novell server and the performance is a bit slow. we have connect the switches with fiber.

the switch is a 4208VL

how can we troubleshoot this problem? or does have anyone a solution?

Thanks

Hi,

Here the explanation of the loss of link :

333 / Port <port-num> - Loss of Link / info / The link on the specified port was lost. RMON_FF_LOSS_OF_LINK

Same for collision and drop :

331 / Port <port-num> - High collision or drop rate. See help. / info / A high collision or drop rate for packets has been reported on the specified port. Refer to the help information for more details. RMON_FF_LOOP_OVER_BAND

You need to check many things :

- wires

- speed-duplex

- NIC drivers

- try an upgrade of your 4200, some problem with autoneg or Intel NIc was fixed

Good Luck.
