Defining an Interface

When you define an interface, you define the interface’s IP address, subnet mask, broadcast address, cost, and the collection of system ports associated with the interface.

Table 3-1 shows the recommended settings for the IP interface parameters if you are setting up the system for management.

Defining an interface defines the IP broadcast domain for frames sourced from the attached segment. To avoid unintentional filtering of IP broadcasts, 3Com recommends that you include all ports. If you do not assign all ports to this interface, be sure that you include the port to which your network management station is attached.

To define an IP interface:

1From the top level of the Administration Console, enter:

ip interface define

You are prompted for the interface’s parameters. To use the value in brackets, press [Return] at the prompt.

2Enter the IP address of the interface.
