9 Administration 

This session introduces security and simple network management protocol 
(SNMP) and time synchronous. 
 
 
 
 
 
 
 
 
 
 
 

9.1 Security 

For system secutiry, suggest to change the default user name and password in 
the first setup otherwise unauthorized persons can access the router and 
change the parameters. 
There are three ways to configure the router, Web browser, telnet and serial 
console.  
 
Press Security to setup the parameters. 
 
 
 
 
 
 

 
For greater security, change the Supervisor 
ID and password for the gateway. If you don’t 
set them, all users on your network can be 
able to access the gateway using the default 
IP and Password root. 
 
You can authorize five legal users to access 
the router via telnet or console. There are two 
UI modes, menu driven mode and command 
mode to configure the router. 
 
Legal address pool will setup the legal IP 
addresses from which authorized person can 
configure the gateway. This is the more 
secure function for network administrator to 
setup the legal address of configuration.
