Strange problem, PIX 515 cant talk to ISP

[m3the01]

Heres the situation. We have 5 static ips and everything runs wonderful if we have the configuration as follows.

ISP->Cisco microswitch 1548->PIX 515 everything is great, wonderful. Here comes the problem the microswitch 1548 is dieing. It Needs a power cycle every 10-14 days and sometimes will not bootup right away. Have to power off and reconnect a couple time.

So lets just drop the microswitch and connect directly to the isp line. Wow now nothing works, i had the isp flush there arp cache and i did to. Waited like 1 hour but nothing. Cant ping out anymore, isp can no longer see the PIX 515 MAC. Nothing works, so i re-attached the microswitch and everything is great.


Thoughts? Its a damn switch, its not doing anything special. Maybe hardware between isp and pix 515 is not compadable(dont think this is the issue, but the isp went down that road). Could the switch be acting as a repeater and the signal is getting degraded??


Any thoughts would be great,

thanks for your time and help,

Steven

Maybe try swapping the cable for a crossover or for a straight through. It might also by the auto-negotiate port settings on the pix (full duplex, half duplex, 10 or 100 megabits...)

Yeah tried the cable swap but nothing. As for the port settings, its on full duplex and 100megabits/second.

My ISP restricts the MAC address of the port I plug into. Did you have to register the old MAC with your ISP?
