To configure FC mapping policies for egress remarking on the 7250 IXR

Purpose

7250 SROS FC mapping policies for egress remarking associate Dot1p, DSCP, and LSP-EXP CoS values with forwarding classes and profiles. A separate policy is configured for each classification type (Dot1p, DSCP, or LSP EXP).

The policies are assigned to a 7250 SROS Egress Remarking policy; see To configure a 7250 SROS Remarking policy.

7250 SROS FC mapping policies are identified by the policy name; policy ID numbers are not used.

The NFM-P provides a default 7250 SROS FC Dot1p mapping policy. The default policy is not configurable, and cannot be deleted. The default policy is assigned to a 7250 SROS Egress Remarking policy when no user-configured policy is explicitly assigned.

7250 SROS FC mapping policies are not supported on all 7250 IXR chassis types and releases. For information about FC mapping policy support on the 7250 IXR, see the NE documentation.

For more information about QoS policy support on the 7250 IXR, see 7250 IXR QoS policies.

Steps
 
1 

If required, configure a 7250 SROS FC Dot1p Mapping policy. Perform the following:

  1. Choose Policies→QoS→SROS QoS→Egress Remarking→7250 SROS FC Dot1p Mapping from the NFM-P main menu. The 7250 SROS FC Dot1p Mapping form opens.

  2. Click Create or choose an existing policy and click Properties. The 7250 SROS FC Dot1p Mapping (Create|Edit) form opens.

  3. Configure the Displayed Name parameter on the General tab.

  4. Click on the FC Classification tab.

  5. Choose a forwarding class in the list and click Properties. The FC Dot1p form opens.

  6. Configure the mapping of forwarding classes, profiles, Dot1p values, and DE values.

    Settings for the Force DE value parameter take effect when the Mark DE bit parameter is set to true.

  7. Save your changes and close the form.

  8. Repeat substep 5 to substep 7 to configure additional FCs, as required.

  9. Click OK to save the policy and close the form, or click Apply to save the policy. See To release and distribute a policy to distribute the policy to NEs.

If required, configure a 7250 SROS FC DSCP Mapping policy. Perform the following:

  1. Choose Policies→QoS→SROS QoS→Egress Remarking→7250 SROS FC DSCP Mapping from the NFM-P main menu. The 7250 SROS FC DSCP Mapping form opens.

  2. Click Create or choose an existing policy and click Properties. The 7250 SROS FC DSCP Mapping (Create|Edit) form opens.

  3. Configure the Displayed Name parameter on the General tab.

  4. Click on the FC Classification tab.

  5. Choose a forwarding class in the list, or click Create. The FC DSCP form opens.

  6. Configure the mapping of forwarding classes, profiles, and DSCP values.

  7. Save your changes and close the form.

  8. Repeat substep 5 to substep 7 to configure additional FCs, as required.

  9. Click OK to save the policy and close the form, or click Apply to save the policy. See To release and distribute a policy to distribute the policy to NEs.

If required, configure a 7250 SROS FC LSP EXP Mapping policy. Perform the following:

  1. Choose Policies→QoS→SROS QoS→Egress Remarking→7250 SROS FC LSP EXP Mapping from the NFM-P main menu. The 7250 SROS FC LSP EXP Mapping form opens.

  2. Click Create or choose an existing policy and click Properties. The 7250 SROS FC LSP EXP Mapping (Create|Edit) form opens.

  3. Configure the Displayed Name parameter on the General tab.

  4. Click on the FC Classification tab.

  5. Choose a forwarding class in the list, or click Create. The FC LSP EXP form opens.

  6. Configure the mapping of forwarding classes, profiles, and LSP-EXP values.

  7. Save your changes and close the form.

  8. Repeat substep 5 to substep 7 to configure additional FCs, as required.

  9. Click OK to save the policy and close the form, or click Apply to save the policy. See To release and distribute a policy to distribute the policy to NEs.
