ROUTER > CONFIG > INTERFACES (NET) > SUB-INTERFACE

This is a read-only field which displays the physical and logical port of the interface using the following

nomenclature: [A.B], where A represents the physical port (network interface is 0, Ethernet is 1) and B

represents the logical port for the Layer 2 protocol (i.e. PVC for Frame Relay, PPP link, etc.) Each

configured logical port is assigned a number corresponding to the order in which they are listed in the L2

Protocol configuration fields.

ROUTER > CONFIG > INTERFACES (NET)> SETUP

Configure the IP parameters for this interface and sub-interface from this menu.

address from a DHCP server. IARP allows the unit to determine the far-end IP address using inverse

ARP.

LOCAL IP ADDRESS

This is the IP address for this PCV. This field is not visible when ADDRESS MODE is set to DHCP

LIENT.

IP NETMASK
