    450 Stops Responding to Ping Periodically, but Always Forwards Frames

    We have this problem on 470's. It happens at the same time multicast traffic is high (checking the igmp snoop shows lots of connections). The 470, 8600 and other switches place responding to pings way down on the list of importance. (Behind things like forwarding packets) If the switch...

    BGP Nortel 8600 to Cisco 6509

    I am having problems communicating BGP between a pair of 8600's (v3.5.1) and a pair of 6509's. I can easily get the 6509's to talk ibgp and, after some experimenting, the 8600's are working on ibgp (ospf has to be working on the 8600's or there's no router id). I cannot, however get the...

    7507 IOS/pcmcia problems

    It turns out that the code we were upgrading from was a custom version. Any linear card that was formatted or written to by that version of code immediately became unusable in any other router. The upgrade solution was to format a card with the custom version of code, copy the image to it...

    7507 IOS/pcmcia problems

    I have several 7507's I'm trying to upgrade. Each one has a 32mb Cisco linear card in slot0:. On one router, I formatted the card and then tftp'd the new IOS over to the card. Then, after changing the boot parameter to reflect the new code name, the router was booted and came up fine on the...
