I have a Pix 501 that is connected on the e0 interface to a Cisco 2950 switch. Been having some problems getting out with it from the internal network and when I do a show interface command on e0 it shows interface is up, line protocol is down.

I've tried different cables to see if that was the problem but that doesn't help. It's a straight through cable connecting the two. I checked the LED's for status and power is on, inside connection has a solid link light. Outside connection blinks once in a while but then goes out. It is out more then blinking. If I plug the cable from the 2950 into any of the 1-4 ports on the back, I have solid lights. I also should say that the light on the 2950 is solid as well.

Could I have a bad port on the Pix? Or could there be something between the Pix and the 2950 that's not correct? Fairly new to the Pix, so any help would be appreciated.

Thanks!
