The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS Multiprotocol Label Switching commands that begin with C.
To configure a class-based tunnel selection (CBTS) tunnel interface type, use the cbts-member tunnel-te command. To restore the system to its default condition, use the no form of this command.
no cbts-member tunnel-te number

You cannot configure the traffic engineering (TE) commands on these class-based tunnel selection (CBTS) member tunnels (auto-bw; backup-bw; description; destination; fowarding-adjacency; inherit; source).
Note All the tunnel-te configured commands, except for exp and path-option, are inherited by the CBTs-member LSP when they are configured on the tunnel headend interface. If the command is entered independently of or on the CBTs-member LSP, it takes precedence and overrides the config on the tunnel headend interface for that CBTs-member LSP. When the configuration is removed from the cbts-member LSP, the configuration on the tunnel headend interface is inherited by the CBTs-member LSP.
This example shows how to configure a CBTS tunnel interface type:

To specify the class name of the policy that you want to create or change, use the class command. To return to the default setting, use the no form of this command.
class [type qos] {class-map-name | class-default}
no class [type qos] {class-map-name | class-default}
|

Configures the Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP). |
To configure a class map, use the class-map command. To return to the default setting, use the no form of this command.
class-map [type qos] [match-all] [match-any] class-map-name
no class-map [type qos] [match-all] [match-any] class-map-name

This example shows how to specify the logical AND for all match statements under this class map:
This example shows how to specify the logical OR for all match statements under this class map:

To enable the control word support, use the control-word command.
control-word {exclude | include}
Specifies to exclude the control word in the pseudowire packet. |
|
Specifies to include the control word in the pseudowire packet. |
|
|
---|---|
A device can receive a packet with or without the control word and the control word capability is negotiated with the peer. However, the device cannot generate a sequence number in the control word if the control word is added to the ingress device.
This example shows how to enable the control word support:

Enters interface pseudowire configuration mode and configures a static pseudowire logical interface. |
To copy the running configuration to the startup configuration, use the copy running-config startup-config command.
copy running-config startup-config
|

---|---|
When you disable the MPLS Label Distribution Protocol (LDP) on the device, no LDP commands are available.
This example shows how to copy the running configuration to the startup configuration:

To configure the cost-limit for an individual TE tunnel, use the cost-limit command.
TE Interface Configuration (config-if)
