A mind-numbing read if ever there was one

Firing up a Fresh 3550 Switch using Auto-configuration

Don’t look here if you’re hoping to actually see a “how-to.” Here’s a link to Cisco page on Switch Auto-Configuration. (I haven’t gone through it, but from what I read I wouldn’t assume it’s going to be easy. Looks like it’s easy on the switch; but you have to configure a ton of stuff!)

So the point of this posting is just to show what displays on your console if you reload or start the switch after erasing the startup-config and a DHCP server happens to be attached. What’s not apparent from the listing is that there will be endless console messages showing attempts to reach a config server.

Would you like to enter the initial configuration dialog? [yes/no]:
00:00:33: %SPANTREE-5-EXTENDED_SYSID: Extended SysId enabled for type vlan
