I am trying to configure a SPAN port to monitor traffic on certain switch ports with an external sniffer. I have had reports that after enabling the SPAN port, the switch is dropping traffic on the monitored ports. Does anyone know of problems like this when using SPAN ports? Thanks.

SPAN port problem on 2924

Is your sniffer running at 10 or 100Meg; half or full duplex? There is a possibility that you are capturing more data than the connection or the sniffer itself can handle. Network General Sniffer documentation says that this can happen under those types of conditions. There is a way to configure them to capture at higher speeds but you still loose some data. Hope this helps.<br>

This alleged problem is with the switch itself. I am told that, after a SPAN port is configured, certain data such as TFTP transfers passes through the switch intermittently. There was no problem before the SPAN port. Ever hear of anything like that? Thanks.
