Configuring ACL

ACL Configuration

User Guide  

  803

DSCP

Specify the DSCP field for the matched packets. The DSCP field of the 

packets will be changed to the specified one.

Local Priority

Specify the local priority for the matched packets. The local priority of the 

packets will be changed to the specified one.

802.1p Priority

Specify the 802.1p priority for the matched packets. The 802.1p priority of 

the packets will be changed to the specified one.

6)  Click 

Apply

.

Viewing the ACL Rules

The rules in an ACL are listed in ascending order of their rule IDs. The switch matches a 

received packet with the rules in order. When a packet matches a rule, the switch stops the 

match process and performs the action defined in the rule.
Click 

Edit ACL

 for an entry you have created and you can view the rule table. We take IP 

ACL rules table for example.

Figure 2-33 

Viewing ACL Rules Table

Here you can view and edit the ACL rules. You can also click 

Resequence 

to resequence 

the rules by providing a Start Rule ID and Step value.

2.1.4  Configuring ACL Binding

You can bind the ACL to a port or a VLAN. The received packets on the port or in the VLAN 

will then be matched and processed according to the ACL rules. An ACL takes effect only 

after it is bound to a port or VLAN.

Note:

 •

Different types of ACLs cannot be bound to the same port or VLAN.

 •

Multiple ACLs of the same type can be bound to the same port or VLAN. The switch matches 

the received packets using the ACLs in order. The ACL that is bound earlier has a higher 

priority.
