Advertisement Address — The Layer 3 Module uses this IP address
when it advertises routes to other stations on the same subnet. In
particular, the Layer 3 Module uses this address for sending RIP
updates. By default, the Layer 3 Module uses a directed advertisement
(all number ones in the host field). The default advertisement address
that the Layer 3 Module provides is appropriate for most networks.
Cost — The Layer 3 Module uses this number, between 1 and 15, to
calculate route metrics. Unless your network has special requirements,
assign a cost of 1 to all interfaces.
State — This status of the IP interface indicates whether the interface
is available for communication. Because the Layer 3 Module is an
internal module, the interface is always up, regardless of the state of
the front panel ports.
VLAN Index — VLAN ID. The VLAN index indicates which 802.1Q
VLAN is associated with that IP interface. When the menu prompts
you for this option, it displays a list of available VLANs.
To display the mappings between the VLAN indexes and the 802.1Q
VLANs, use the
See Chapter 7, "Displaying VLAN Parameters" for more information
about this command.
You can display summary information about all IP interfaces configured
on the Layer 3 Module. The detail display contains summary information
and information about the advertisement address.

The following example shows an IP interface summary display:
When you define an IP interface, you specify several characteristics

The default values that the Layer 3 Module provides for some interface
characteristics are appropriate for most networks.
