because you may:

Services
You can configure the iSR6152 router to suit the demands of your environment
using a variety of router services. Familiarize yourself with the following router
services and determine which ones you need:
 Telnet enables router management over a Telnet connection.
 Router management provides for out-of-band router management using
Router Manager.
 SNMP provides monitoring of the router using third-party applications that
use SNMP.
 Network time protocol (NTP) enables synchronizing the router and the
workstation dates and times with an NTP server. NTP is disabled (and not
configured) by default.
 File transfer protocol (FTP) enables transferring files rapidly between the
workstation and router using FTP.
Security
Passwords provide router security. Router Manager requires a password each
time a user logs into the utility. When connected, Router Manager prompts for an
administrative password before it accepts configuration changes.
The CLI also requires the user to enter a user ID and password to start. CLI must
be in an admin session to perform any set operations. An admin session requires
a password.
The default password for both these management tools is “password” for the
default user ID of “guest.” The default administrative password is “config.”
After you are logged on, you can change the password using the utility’s security
features.
