router. To ensure basic security, you must define the root password during initial configuration. If a root password is not defined, you cannot commit configuration settings to take effect on the router.

If you use a plain-text password, the router displays the password as an encrypted string so that users viewing the configuration cannot easily see the password.

The root password must meet the following conditions:

■The password must be at least 6 characters long.

■You can include most character classes in a password (alphabetic, numeric, and special characters), except control characters.

■Valid passwords must contain at least one change of case or character class.

Time Zone and System Time

You define the time zone for the location where you plan to operate the Services Router by using a designation that consists of the following information for the location:

■Name of the continent or ocean—For example, America or Atlantic

■Name of the major city or other geographic feature in the time zone—For example, Detroit or Azores

A Network Time Protocol (NTP) server provides accurate time across a network. The router synchronizes the system time with the NTP server, and periodically accesses the NTP server to maintain the correct time.

The time zone and system time must be accurate so that the router schedules events and operations as expected.

Network Settings

A Domain Name System (DNS) server on the network maintains a database for resolving hostnames and IP addresses. Network devices can query the DNS server by hostnames rather than IP addresses. The router accesses the DNS servers that are added to the configuration to resolve hostnames in the order in which you list them.

If you plan to include your router in several domains, you can add these domains to the configuration so that they are included in a DNS search. When DNS searches are requested, the domain suffixes are appended to the hostnames.

Default Gateway

A default gateway is a static route that is used to direct packets addressed to networks not explicitly listed in the routing table. If a packet arrives at the Services Router with an address that the router does not have routing information for, the router sends the packet to the default gateway. The default gateway entry is always present in the routing and forwarding tables.
