Re: Debug

yeah i thought maybe you had cut some of it off...

I am using GNS3 and this is my show version:

Router#sh ver
Cisco IOS Software, 3700 Software (C3725-ADVENTERPRISEK9-M), Version
12.4(21a), RELEASE SOFTWARE (fc1)

but i have no clue about the state values, and without access to the IOS
code and the internal docs at Cisco not sure if we ever will....

you can see the debug messages come and go and the state changes, so might
be able to figure out each one if you played with it long enough, not sure
it would be worth the effort or not, by doing shut no shut on the
interfaces...

Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int f0/0
Router(config-if)#ip add
