Defining a traffic class
Configuration guidelines
When you configure the logical AND operator for a traffic class, follow these restrictions and guidelines:
• A QoS policy that contains the traffic class cannot be applied correctly if you configure either of the
following for the traffic class:
{
Multiple if-match commands for a match criterion other than VLAN ID.
{
Multiple values in one if-match command for a match criterion other than VLAN ID.
• The actual logical operator for the traffic class is OR if you configure either of the following for the
traffic class:
{
Multiple if-match commands for VLAN ID match criteria.
{
Multiple values in one if-match command for VLAN ID match criteria.
• The actual logical operator for the rules in an ACL match criterion is OR.
If a traffic class includes the control-plane protocol or control-plane protocol-group match criterion, the
QoS policy that uses this traffic class can be applied only to a control plane.
Configuration procedure
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a traffic class and
enter traffic class view.
traffic classifier classifier-name
[ operator { and | or } ]
By default, no traffic class exists.
3. Configure match criteria. if-match match-criteria
By default, no match criterion is
configured.
For more information, see the
if-match command in ACL and
QoS Command Reference.
Table 2 Available match criteria
Option Description
acl [ ipv6 ] { acl-number | name
acl-name }
Matches an ACL.
The acl-number argument is in the range of 2000 to 3999 for an IPv4 ACL,
2000 to 3999 for an IPv6 ACL, and 4000 to 4999 for an Ethernet frame
header ACL.
The acl-name argument is a case-insensitive string of 1 to 63 characters,
which must start with an English letter, and to avoid confusion, it cannot be
all.
any Matches all packets.
control-plane protocol
protocol-name&<1-8>
Matches the control plane protocols.
The protocol-name-list&<1-8> argument is a list of system-defined control
plane protocols. &<1-8> indicates that you can enter up to eight
system-defined control plane protocols.
