traffic classifier 
classifier-name [ operator 
{ and | or } ] 
Required 
By default, the and keyword is 
specified. That is, the relation 
between the rules in the class 
view is logic AND. This 
operation leads you to class 
view.
 
Define a rule used to match 
packets
 
if-match match-criteria 
Required
 
 
match-criteria: Matching rules to be defined for a class. 
Table 2-1 describes the available forms of this 
argument.  
Table 2-1 The form of the match-criteria argument 
Form  Description 
acl access-list-number 
Specifies an ACL to match packets. The access-list-number 
argument is in the range 2000 to 4999.  
In a class configured with the operator and, the logical relationship 
between rules defined in the referenced IPv4 ACL is or.
 
acl ipv6 access-list-number 
Specifies an IPv6 ACL to match IPv6 packets. The 
access-list-number argument is in the range 2000 to 3999.  
In a class configured with the operator and, the logical relationship 
between rules defined in the referenced IPv6 ACL is or.
 
any 
Specifies to match all packets. 
 
customer-dot1p 8021p-list 
Specifies to match packets by 802.1p precedence of the customer 
network. The 8021p-list argument is a list of CoS values, in the 
range of 0 to 7.  
 
Even though you can provide up to eight space-separated CoS 
values for this argument, the S5120-EI switch supports only one 
CoS value in a rule. If you configure multiple CoS values in a rule, 
the rule cannot be issued. 
customer-vlan-id vlan-id-list 
Specifies to match the packets of specified VLANs of user 
networks. The vlan-id-list argument specifies a list of VLAN IDs, in 
the form of vlan-id to vlan-id or multiple discontinuous VLAN IDs 
(separated by space). You can specify up to eight VLAN IDs for 
this argument at a time. VLAN ID is in the range 1 to 4094.  
In a class configured with the operator and, the logical relationship 
between the customer VLAN IDs specified for the 
customer-vlan-id keyword is or.
 
destination-mac mac-address 
Specifies to match the packets with a specified destination MAC 
address.
