SCCP ALG Configuration Overview

The Skinny Client Control Protocol Application Layer Gateway (SCCP ALG) is enabled by default on the device—no action is required to enable it. However, you might choose to fine-tune SCCP ALG operations by using the following instructions:

1. Conserve network resources and maximize throughput. For instructions, see:

   • Example: Setting SCCP ALG Inactive Media Timeouts (J-Web)
   • Example: Setting SCCP ALG Inactive Media Timeouts (CLI)

2. Enable unknown messages to pass when the session is in Network Address Translation (NAT) mode and route mode. For instructions, see:

   • Example: Allowing Unknown SCCP ALG Message Types (J-Web)
   • Example: Allowing Unknown SCCP ALG Message Types (CLI)

3. Protect the SCCP clients from denial-of-service (DoS) flood attacks. For instructions, see:

   • Example: Configuring SCCP ALG DoS Attack Protection (J-Web)
   • Example: Configuring SCCP ALG DoS Attack Protection (CLI)
