Adding a DSCP Configuration

Note: Each DSCP configuration is saved to the configuration file in the order in which it is added.

To add a DSCP configuration:

  1. Log in to the platcfg utility using one of two methods, either from the system console using root or through an SSH remote session using admusr.
    • To access the platcfg utility from the system console:
      1. Log in as root.
      2. Enter su - platcfg.
    • To access the platcfg utility through an SSH remote session:
      1. Log in as admusr.
      2. Enter sudo su - platcfg.

    Note: The dash (-) is required in the su - platcfg or the sudo su - platcfg command to ensure proper permissions.

  2. Select DSCP Config from the Policy Configuration Menu screen and press Enter.
  3. Select Add New DSCP Configuration from the DSCP Configuration Menu screen and press Enter.
  4. Select the appropriate interface for the new configuration from the Select Interface screen, then select OK and press Enter, where:

    • SIG-A is used to connect to the customer signaling A network,
    • SIG-B is used to connect to the customer signaling B network,
    • SIG-C is used to connect to the customer signaling C network and is used to internally connect to either MRA or MPE devices when both SIG-A and SIG-B are used for SCTP multi-homing, and
    • OAM is used to connect to the customer management network and for internal connection between the cluster and site.
    Note: If more than one DSCP configuration is added on the same network interface (for example, SIG-A), the output packets sent from this interface are from the latest DSCP configuration added. The new DSCP configuration (with the same or greater scope in output packets of this network interface) takes precedence over any previous DSCP configurations.
    Note: If one interface has both VIP and IP and associates DSCP only with VIP, the packets sent from this interface may not be marked with DSCP as expected because the application may send packets from the server IP instead of the VIP.

  5. Specify the IP Protocol Version, Source IP Address, and Destination IP Address to associate with the new configuration on the Input Source IP and Destination IP screen.

    Note: If settings are not specified, default settings are used.

  6. Select OK and press Enter.
  7. Select the Code Point to use with this configuration from the Code Point selection screen, then select OK and press Enter.
