L2TP Parameters

The parameter descriptions follow.

Parameter: L2TP IP Interface Address

Path: Configuration Manager > Protocols > IP > L2TP > L2TP IP Interface

Default: None

Options: Any unique IP address

Function: Specifies the IP address that identifies the L2TP IP interface for the LNS. You must provide an address for each slot configured as an LNS.

Instructions: Enter a unique IP address. This address applies for the entire router slot.

MIB Object ID: Not Applicable

Parameter: Subnet Mask

Path: Configuration Manager > Protocols > IP > L2TP > L2TP IP Interface

Default: None

Options: A 32-bit IP subnet mask

Function: Specifies the network and subnet portion of the L2TP IP interface address.

Site Manager automatically calculates a natural subnet mask based on the class of the network address. For example, if you enter a Class C address, the subnet mask will be 255.255.255.0.

To configure more subnets for your network, you can change this natural mask.

Instructions: Accept the assigned natural subnet mask or enter a new one. You are not restricted to entering a natural mask. For example, if the L2TP IP address is 192.32.16.55, you can enter a subnet mask of 255.255.255.192.

MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.1.24.1.6
