Usually when I reboot a router after cleaning it’s startup config…I just copy and paste this on all my routers and switches just to get started (if I’m not using pre-configed stuff):
en
conf t
no ip domain-lookup
line con 0
exec-time 0 0
logg sync
hostname
Also, on my term server, since I always have stuck sessions from my last lab, I clear them all up by copying and pasting:
clear line 1
clear line 2
clear line 3
clear line 4
clear line 5
clear line 6
clear line 7
clear line 8
clear line 9
clear line 10
clear line 11
clear line 12
clear line 13
