    Hello, I hope it's OK to ask this here.

    Home lab. I've been trying to configure a Cisco 2621XM to do various things.

    it was working fine. Basic config, banners, passwords, enable secret. doing dot1q trunking for 5 VLANs on sub interfaces, router on stick setup. Not much traffic though. Just ping tests from couple of hostes. I had RIP to enabled. DHCP serving for one of those VLANs, which only had one host attached. No encryption, SSH. A serial port configured with a PPP link to another router.

    I then tried to get it to do NAT for the VLANS, over the serial link. Got as far as defining serial 0/0 as outside local, then got a message about running out of memory. . I then turned off RIP in the hope of freeing up some memory and rebooted. Now I get the below error upon rebooting. Even after a cold start.

    I'm guessing it means it's run out of flash space. The config wasn't that big though surely. Or do i need more NVRAM? Can I break into Romo mode from the consol and clear the config back to factory defaults? If so, how? If the flash is corrupted, how do I break into Romo mode and copy the IOS image back from TFTP? (Luckily I have backed it up.)

    Thanks for any tips / pointers. I've got the CCENT exam in couple of weeks. Whilst VLANs don't come into the until ICND2, I like setting up full configs from scratch as it helps me remember the ICND1 level stuff on the way.

    And sorry for long post. if it's extra flash / NVRAM I need, I want to jump on Ebay and get on with it, so had to ask.

    Cheers.

    Acording to Cisco (http://www.cisco.com/en/US/docs/ios/11_0/system/message/emisc.html)

    extract here:

    Error Message

    Unexpected exception to CPU vector [dec], PC = [hex]
    Explanation Either a hardware or a software problem has occurred.
    Recommended Action Refer to the Recommended Action for the first "Bus Error control register" message in this section

    Referring to that section, points to either software or hardware .... ultimatley not a lot you can do, looking around the web other people have broke into ROMMON mode and tried different IOS's / erasing configs but with no joy .... :0(

    Take a look at the site and have a google mate

    Ta. Gutted if it's unsaveable. Was favourite in my lab setup. I'll have a look tomorrow.
