Parameters

te-class-index: Specifies a TE class index in the range of 0 to 7.

class-type class-type-number: Specifies a CT by its number in the range of 0 to 3. The system supports

four CTs, CT 0 through CT 3.

priority priority-number: Specifies a priority number in the range of 0 to 7.

Usage guidelines

For a traffic trunk from a CT, the setup or/and holding priority of the LSP transporting the traffic trunk must

be the priority specified for the CT in the TE class.

Note the following guidelines:

• When you use the ds-te te-class command to configure a TE class, make sure to specify a CT-priority

pair different from that in any existing TE class.

• When you use the undo ds-te te-class command to restore the default settings for a TE class, make

sure the default CT and priority values of the TE class are not the same as those of an existing TE

class.

• After a TE class is modified, the device notifies the IGP to re-advertise the bandwidth information of

all TE interfaces, and removes and then re-establishes the CRLSPs of the TE class on all TE interfaces.

Examples

# Specify CT 2 and priority 3 for TE class 7 in IETF DS-TE mode.
