access 

Group of commands that limit access to the CR-SEH through the console port and telnet 
sessions. Note that there is no command to enable or disable the telnet session password. It 
is always enabled.

 sets the requirement that a password be entered when starting a console 

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). 

show

 will display the setting of the 

ip command and the list of IP addressed entered when enabled. 

ftpw 

This command changes the password required to initiate an FTP session with the CR-SEH. 
The default password is “Cirronet” (without quotes). It is not possible to disable this 
password. 

password 

This command changes the password required to initiate a telnet session with the CR-SEH 
and initiate a serial connection through the console port when enabled. The default password 
is “Cirronet” (without quotes). It is not possible to disable the password requirement for a 
telnet session, but it is possible to disable the password requirement for the console
