How to Commission the Cisco AS5850 Universal Gateway
Step 2 Enter domain-name service global configuration commands to support EXEC-shell users.
ip domain-lookup
ip host aurora 172.22.100.9
ip domain-name the.doc
ip name-server 172.22.11.10
ip name-server 172.22.12.10
Table 9 describes the previous commands.
Task 9. Testing Asynchronous EXEC-Shell Connections
This task verifies that the following components are working:
• Physical asynchronous data path
• Basic modem links
• Basic IP functionality to support EXEC-shell sessions
Table 8 IP Routing Commands
Command Purpose
ip subnet-zero
Specifies that 172.22.0.0 is a valid subnet.
no ip source-route
Tightens security by ensuring that IP-header
packets cannot define their own paths through the
universal gateway.
ip classless
Turns off traditional IP network class distinctions
in the gateway (Class-A, Class-B, Class-C).
Table 9 Domain-Name Commands
Command Purpose
ip domain-lookup
Enables IP domain-name lookups.
ip host aurora 172.22.100.9
Creates a local name-to-address map. This map is
useful when the gateway is not entered in a DNS
server.
ip domain-name the.doc
Tells the gateway how to qualify DNS look ups. In
this example, the.doc is appended to the end of
each name that is looked up.
ip name-server 172.22.11.10
ip name-server 172.22.12.10
Specifies the primary and secondary name servers.
They are used for mapping names to IP addresses.
