Usage Guidelines
It is possible to configure L2TPv3 (or GRE) tunnel marking and the ip tos command at the same time.
However, Modular Quality of Service (QoS) Command-Line Interface (CLI) (MQC) (L2TPv3 or GRE)
tunnel marking has higher priority over ip tos commands, meaning that tunnel marking always rewrites
the IP header of the tunnel packet and overwrites the values set by ip tos commands. The order of
enforcement is as follows when these commands are used simultaneously:
OL-23890-01
set ip precedence tunnel precedence-value
no set ip precedence tunnel precedence-value
Number from 0 to 7 that identifies the precedence value of the tunnel header.
