I have a few questions regarding the below configurations:
line con 0
transport input none
line vty 0 4
password 7 xxxxxxxxxx
line vty 5 15
password 7 yyyyyyyyyy
username pass password 7 zzzzzzzzz
enable secret vvvvvv
1) From these configurations, why we need to set both different passwords for vty 0 4 and vtp 5 15?
2) What is the purpose of divide it to two parts instead of using vty 0 15?
3) From this configuration, what is the password to access vty 0 4 and vty 5 15?
Is it sharing the same password?
4) Can i say that line vty is activate when we want to telnet to it? For line con 0, it is activate when we need to console in to the switch? But what is the password for line con?
