Module "MUX" (Multiplexer for Applications Traffic)

R80.20 introduced a new layer between the Streaming layer and the Applications layer - MUX (Multiplexer).

Applications are registered to the Streaming layer through the MUX layer.

The MUX layer chooses to work over PSL (passive streaming) or CPAS (active streaming).

Syntax

• On the Security Gateway Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources. / each Cluster Member Security Gateway that is part of a cluster., run in the Expert mode:

  fw ctl debug -m MUX + {all | <List of Debug Flags>}

• On the Scalable Platform Security Group A logical group of Security Appliances (in Maestro) / Security Gateway Modules (on Scalable Chassis) that provides Active/Active cluster functionality. A Security Group can contain one or more Security Appliances / Security Gateway Modules. Security Groups work separately and independently from each other. To the production networks, a Security Group appears a single Security Gateway. In Maestro, each Security Group contains: (A) Applicable Uplink ports, to which your production networks are connected; (B) Security Appliances (the Quantum Maestro Orchestrator determines the applicable Downlink ports automatically); (C) Applicable management port, to which the Check Point Management Server is connected., run in the Expert mode:

  g_fw ctl debug -m MUX + {all | <List of Debug Flags>}
