To configure a 7210 MPLS LSP-EXP Mapping policy

Purpose

A 7210 MPLS LSP-EXP Mapping policy defines a local mapping of forwarding classes to MPLS LSP-EXP bits for traffic ingressing the switch from an MPLS network. The policy is used primarily for an RSVP LSP with FRR one-to-one. For LDP LSPs, or when using FRR facility, the use of a single MPLS LSP-Exp Map policy for all IP interfaces is recommended.

The policy is assigned to a network policy of network interface type; see To configure a 7210 and 1830 network policy . You can also assign the policy to an NE using the NE properties form. The 7210 MPLS LSP-EXP Mapping policy is called an MPLS LSP-EXP Profile when it is assigned to a network policy or NE.

The LDP Local FC parameter must be set to true in NE properties in order for 7210 MPLS LSP-EXP Mapping policy local definitions to take effect.

The NFM-P provides one default MPLS LSP-EXP Mapping policy (policy ID 1). The default policy cannot be modified or deleted. In the default policy, EXP bit values 0 and 2 are out-of-profile. The other six EXP bit values (1, 3, 4, 5, 6, 7) are in-profile.

The MPLS LSP-EXP Mapping policy is supported on the following MPLS-enabled 7210 SAS devices:

  • 7210 SAS-M (in network mode)

  • 7210 SAS-Mxp

  • 7210 SAS-R

  • 7210 SAS-S

  • 7210 SAS-Sx

  • 7210 SAS-T (in network mode)

  • 7210 SAS-X

Steps
 
1 

Set the LDP Local FC parameter to true.

Note: For 7210 SAS NEs, the LDP Local FC parameter is read-only and is set to true.

Perform the following:

  1. Right-click on a 7210 SAS NE in the navigation tree and choose Properties. The Network Element (Edit) form opens.

  2. Click on the LDP QoS Config tab and configure the LDP Local FC parameter, as required.

  3. Save your changes and close the form.

2 

Choose Policies→QoS→SROS QoS→Network→7210 MPLS LSP-EXP Mapping from the NFM-P main menu. The 7210 MPLS LSP-EXP Map Policies form opens.

3 

Click Create or choose a policy and click Properties. The 7210 MPLS LSP-Exp Map, Global Policy (Create|Edit) form opens.

4 

Configure the required parameters on the General tab.

5 

Map profile states to MPLS LSP-EXP bits.

  1. Click on the MPLS LSP-Exp Bits tab.

  2. Select an LSP EXP bit and click Properties. The MPLS LSP-Exp Map Profile form opens.

  3. Configure the Profile parameter.

  4. Save your changes and close the form.

6 

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.
