I have a weird one. I have a 1721 loaded with a very recent IOS image. FA0 is pointing to the internet and is configured for DHCP. My WIC-4ESW is on the private LAN. The LAN has a four port 3Com gigabit consumer switch. My PC and my router are plugged into the 3Com. The router boots fine and is ready for connections. But it drops straight to ROMMON the moment I turn on OR off my PC. I then have to reboot the router for it to be okay. The motherboard of the PC is a D875PBZ. Suggestions?
Sorry it took so long to get back to you. That whole "work" thing gets in the way of the "life" thing. Anyway, I think I have figured it out. I have another computer to use for logging collection. I moved the console cable to it and turned on the Intel box. The router did not drop to ROMMON. So it looks like there is some kind of a power surge or COM command sent out at turn on and turn off that throws the 1721 to ROMMON. I tried to use syslog to capture what was happening but the router did not provide any more information. It just left IOS and went to ROMMON. I also used CONT command in ROMMON and the router went back to IOS. So I think it's just a strange thing between the 1721 console cable and the Intel board's COM port.
