Patton electronic SmartNode 4110 Series manual Configuring an interface as a point-to-point link

SmartWare Software Configuration Guide 10 • IP interface configuration

The following example shows how to define the MTU of the IP interface lan to 1000 and to adjust the MSS in both directions to MTU-40. Use the following commands in IP context configuration mode.

node(ctx-ip)[router]#interface lan node(if-ip)[lan]#mtu 1000 node(if-ip)[lan]#tcp adjust-mss rx mtu node(if-ip)[lan]#tcp adjust-mss tx mtu

Configuring an interface as a point-to-point link

A point-to-point network joins a single pair of routers. It is in particular used for interfaces, which have a bind- ing to a Frame Relay PVC.

Mode: Configure

Step	Command	Purpose
1	node(cfg)#context ip router	Selects the IP router context
2	node(ctx-ip)[router]#interface name	Selects the defined interface name for configuration
3	node(if-ip)[name]#point-to-point	Configures the interface ifname as point-to-point link

Example: Configuring an interface as a point-to-point link

The following example shows how to define the interface lan as point-to-point link. Use the following com- mands in configuration mode.

node(cfg)#context ip router node(ctx-ip)[router]#interface lan node(if-ip)[lan]#point-to-point

Displaying IP interface information

The show ip interface command displays IP information for all interfaces. The command is available in operator execution mode or in any of the administrator execution modes.

Mode: Operator execution or any administrator execution

Step Command Purpose

1node>show ip interface Displays the IP information for all interfaces

Example: Displaying IP interface information

The following example shows how to display the IP information for all interfaces by using the show ip interface command from operator execution mode.

node>show ip interface
