Configuration restrictions and guidelines • If a class that uses the AND operator has multiple if-match acl, if-match acl ipv6, if-match customer-vlan-id or if-match service-vlan-id clauses, a packet that matches any of the clauses matches the class. • To successfully execute the traffic behavior associated with a traffic class that uses the AND operator, define only one if-match clause for any of the following match criteria and input only one value for any of the following list arguments. To create multiple if-match clauses for these match criteria or specify multiple values for the list arguments, specify the operator of the class as OR and use the if-match command multiple times. { customer-dot1p 8021p-list { destination-mac mac-address { dscp dscp-list { ip-precedence ip-precedence-list { service-dot1p 8021p-list { source-mac mac-address Configuration procedure To define a class: Step 1.

The operator of a class can be AND or OR: • AND-A packet is assigned to a class only when the packet matches all the criteria in the class. • OR-A packet is assigned to a class if it matches any of the criteria in the class.

Configuration restrictions and guidelines
•
If a class that uses the AND operator has multiple
if-match
acl
,
if-match acl ipv6
,
if-match
customer-vlan-id
or
if-match
service-vlan-id
clauses, a packet that matches any of the clauses
matches the class.
•
To successfully execute the traffic behavior associated with a traffic class that uses the AND operator,
define only one
if-match
clause for any of the following match criteria and input only one value for
any of the following
list
arguments. To create multiple
if-match
clauses for these match criteria or
specify multiple values for the
list
arguments, specify the operator of the class as OR and use the
if-match
command multiple times.

The operator of a class can be AND or OR:
•

—A packet is assigned to a class only when
the packet matches all the criteria in the class.

—A packet is assigned to a class if it matches
