Page 147: Set Ip Precedence Tunnel
Release Modification 15.1(2)SNG Support for this command was introduced on the Cisco ASR 901 router. 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.
Page 148 Specifies the ToS level for IP traffic in the TN3270 server. set ip dscp tunnel Sets the DSCP value in the header of an L2TPv3 tunneled packet. Cisco ASR 901 Aggregation Services Router Command Reference Guide 1-134 OL-26031-07...

Page 155 Command History Release Modification 15.1(2)SNG Support for this command was introduced on the Cisco ASR 901 router. Usage Guidelines Committed Information Rate This command calculates the committed information rate (CIR) on the basis of a percentage of the available bandwidth on the interface. Once a policy map is attached to the interface, the equivalent CIR value in bits per second (bps) is calculated on the basis of the interface bandwidth and the percent value entered with this command.
