I have four brand new 2620's. All running the same firmware version. Two of them work perfectly when applying sourece-port filters. The other two allow me to create the named-list, but the moment I try to apply it to a port, the switch CPU utilization jumps to 100%, the switch stops responding and does not recover. A hard reset is required each time this happens. This happens even when there is no traffic on the switch, while connected to the console port. Is this a bug in the frimware? Is it a hardware failure? Has anyone seen this before?
Below are two configs. The first one (1Sw1) crashes when ports are added the lists. The second one (BSw1) works fine as you can see from the config, it has ports added to the lists.
