Cisco SCE 8000 CLI Command Reference

Chapter 2 CLI Command Reference

mpls

Configures the MPLS environment. Up to a maximum of 15 MPLS labels per packet are supported.

When all IP addresses are unique and MPLS labels are not mandatory (a non-MPLS/VPN environment),

use the traffic-engineering skip form of this command.

To set the MPLS configuration to the default value, use the default form of this command.

Command History This table includes the following release-specific history entries:

Usage Guidelines Use this command as follows:

• traffic-engineering skip

Any packets that are injected by the Cisco SCE into the MPLS labeled traffic (block or redirect) are

sent with no MPLS labels. Use this mode when the MPLS labels in the traffic are used only for traffic

engineering, such as QOS, and not for routing.

This mode is the default, and it should be changed only if MPLS is used for routing in the network

and block or redirect is being employed. However, first verify that no private IP conflicts exist in the

network.

• vpn skip

Use this command when all IP addresses are unique, MPLS labels are used, and the labels used for

injection are the correct ones, as seen on the flow. This mode can be used when the MPLS labels are

used for routing or for VPNs (assuming no private IP addresses are being used).

The vpn skip mode is an asymmetric Layer 2 mode. You should expect reduced performance and

capacity, because the system must follow the flow and keep the Layer 2 information.
