46.3.11 Setting the Matchup Data Flow of the QoS Policy Mapping
The classification rule of the QoS data flow means the filtration rule configured by the administrator according
to management requirements. It can be simple, for example, flows with different priorities can be identified by
the ToS field of the IP packet’s header, or complicated, for example, the packets can be classified according
to the related information about the comprehensive link layer, the network layer and the transmission layer,
such as the MAC address, the source address of IP, the destination address or the port ID of the application.
In general, the classification standard is limited in the header of an encapsulated packet. It is rare to use the
content of a packet as the classification standard.
Enter the policy configuration mode, set the match-up data flow of policy and replace the previous settings
with this data flow according to the following steps:
Command Purpose
config
Enters the global configuration mode.
[no]policy-map name Enters the configuration mode of the QoS
policy map.
name stands for the name of the policy.
description description-text Sets the description of the QoS policy.
description-text stands for the text to
describe the policy.
classify {any | cos cos | icos icos |
vlan vlanid | ivlan ivlanid | ethernet-
type ethernet-type | precedence
precedence-value | dscp dscp-value |
tos tos-value | diffserv diffserv-value |
ip ip-access-list | ipv6 ipv6-access-list
Matches up with any packet.
Configures the matched COS value which
ranges between 0 and 7.
icos stands for the matched inner COS value
which ranges between 0 and 7.
