L2TP Settings

Type

no-config Sets the entire PortMaster 4 to have no L2TP configuration if set globally on the manager module. A line board set with no-config has no L2TP configuration of its own but inherits from the system manager module if the manager is configured for L2TP.

disable Disables L2TP on the entire PortMaster 4 if set globally on the manager module. If set on a line board, disable turns of L2TP on that board and prevents the board from inheriting the L2TP configuration of the manager module.

LAC Enables the entire PortMaster 4 as a LAC if set globally on the manager module. If set on a Quad T1 or Tri E1 board, this option enables the board as a LAC. A LAC can answer calls and process them by using L2TP.

LNS Enables the entire PortMaster 4 as an LNS if set globally on the manager module. If set on a Quad T1, Tri E1, or LNS board, this option enables the board as an LNS. On an LNS, any line ports are automatically set as T1 or E1 ports and can no longer be used for dial-in. The virtual S0 ports become W1 ports.

Authenticate Remote

If enabled, sets the PortMaster 4 to initiate authentication with the other side of the L2TP connection before it creates a tunnel.

Choose Random Tunnel Endpoint

If enabled, sets the PortMaster 4 to choose the tunnel end point randomly from the list of tunnels end points returned by RADIUS. Otherwise, the PortMaster 4 is set to select a tunnel end point serially.

Secret

Sets the global password that the PortMaster 4 uses to respond to L2TP tunnel authentication requests. Password is a string of up to 15 ASCII characters.
