The mpls-tp channel-type command specifies the associated channel header (ACH) label value.
By default, the ACH label value is 0x7ffa.
Usage Scenario
An ACH label identifies a packet type. 0x7ffa and 0x8902 identify MPLS-TP OAM packets. 0x7ffa identifies MPLS-TP OAM packets in compliance with Y.1731. 0x8902 identifies MPLS-TP OAM packets in compliance with relevant standards .
Configuration Impact
MPLS-TP OAM packets with the specified ACH label value are sent.
