connection. The password is set using the 

password

 command. The default setting is 

disabled. 

console disable

 removes the password requirement. 

 

ip enable 

sets limitations set on initiating a telnet session to the CR-SEH. When enabled, 

only network devices with IP addresses on the list of IP addresses added can initiate a telnet 
session with the CR-SEH. Up to 10 IP addresses can be added to the list. The list is modified 
with the 

add

 and 

delete

 subcommands. 

ip disable

 allows telnet sessions to be initiated 

from any IP address (a password will still be required).
