Switch Security 6-21
6.4.2.3 Editing an Existing Rule
As network and access permission requirements change, existing ACL rules need to be modified to be
relevant with new client access requests.
To modify an existing ACL rule:
1. Select Security > Wireless Firewall from the main tree menu.
2. Click the Configuration tab.
3. Click the ACL tab.
4. Select an ACL from the ACLs field.
The rules associated with the selected ACL display in the Associated Rules section.
5. Click the Edit button within the Associated Rules field.
6. Use the Precedence field to modify the precedence (priority) between 1 and 5000.
The rules within an ACL are applied to packets based on their precedence value. Rules with lower
precedence are always applied first.
7. Use the Operation drop-down menu (if necessary) to modify the permit, deny or mark designation for the
ACL. If the action is to mark, the packet is tagged for priority.
8. Select the Logging checkbox to generate log messages when a packet has been forwarded, denied or
marked based on the criteria specified in the access lists.
9. If mark is selected from within the Operations drop-down menu, the Attribute to mark field is enabled.
Select the 802.1p (0 - 7) or TOS(0 - 255) or DSCP(0-63) checkbox and define the attribute receiving
priority with this ACL mark designation.
NOTE: If adding an access control entry to an ACL using the switch SNMP interface,
Precedence is a required parameter.
