Command History
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:
1. set ip dscp tunnel or set ip precedence tunnel (L2TPv3 or GRE tunnel marking)
dscp-value Number from 0 to 63 that identifies the tunnel header value. The following
reserved keywords can be specified instead of numeric values:
• EF (expedited forwarding)
• AF11 (assured forwarding class AF11)
