QoS Features, Commands, and Changes
Cisco IOS Release:
Release 12.2(31)SB2
Description:
This command was introduced on the PRE3.
Enhancements to the modular quality of service CLI (MQC) allow you to classify packets on the L2TP
access concentrator (LAC) based upon the IP type of service (ToS) bits in an embedded IP packet. The
classification is used to police ingress traffic according to the DSCP value.
Cisco IOS Release:
Release 12.2(33)SB
Description:
This command was introduced on the PRE4.
match Commands
Cisco IOS Release:
Release 12.0(17)SL
Description:
The
match
command was introduced on the PRE1 to enable you to define the following
match criteria for a class map:
•
match-all
Command—Indicates that a packet must match all of the match criteria specified.
•
match-any
Command—Indicates that a packet must match only one of the match criteria specified.
•
match access-group
Command—Indicates that a packet must match one of the predefined access
control list (ACL) statements.
•
match input-interface
Command—Indicates that the input interface on which the packet arrives
must match the value you set using the
set input-interface
command.
•
match ip dscp
Command—Indicates that the IP DSCP value of the packet must match the value you
set using the
set ip dscp
command.
•
match ip precedence
Command—Indicates that the IP precedence value of the packet must match
the value you set using the
set ip precedence
command.
•
match ip rtp
Command—Indicates that the IP Real-Time Transport Protocol (RTP) value of the
packet must match the value you set using the
set ip rtp
command.
•
match qos-group
Command—Indicates that the QoS group value of the packet must match the
value you set using the
set qos-group
command.
•
match not
Command—Indicates that the packet must not match the criteria you set. You can use
the
match not
command with any match criteria.
For example, to classify packets that do not have a specific class of service value, enter the
match not cos
command in the appropriate class map as a match criterion. The router classifies a
packet when the CoS value of the packet does not match the value you set using the
set cos
command.
Cisco IOS Release:
Release 12.0(22)S
Description:
This command was enhanced to enable you to match the MPLS experimental (EXP) bit
value of the class. If you specify the
match mpls experimental
command, the router classifies a packet
when the MPLS EXP value of the packet matches the value you set using the
set mpls experimental
command. The
match mpls experimental
command is available only on the PRE1.
