Hi all. I lurked on this list for a while last year, and decided come back
and visit.
On a cert note, I have passed CCNA and BCRAN, Switching will be next week
... Damn VLAN's .. :-)
As for your flapping D channel:
Are you using NFAS ?? And why would you take down B channels from the router
? We usually use state 2 (busy)on NFAS from just about any switchtype on the
planet, and everyhting works fine (for testing disco's prior to sending out
orders). I would be curious to see how your SerXX:23 are set up, and what
IOS u r using.
