3. Click the Add button within the Associated Rules field.
4. Use the Precedence field to enter a precedence (priority) value between 1 and 5000.
The rules within an ACL will be applied to packets based on their precedence value. Rules with lower
precedence are always applied first.
5. Use the Operation drop-down menu to define a permit, deny or mark designation for the ACL. If the
action is to mark, the packet is tagged for priority.
6. 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.
7. 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) checkbox and define the attribute receiving priority
with this ACL mark designation.
8. If the selected Protocol is icmp, click the Protocol Options button to configure the ICMP Type
and ICMP Code.
NOTE If adding an access control entry to an ACL using the switch SNMP interface,
Precedence is a required parameter.
NOTE If wanting to block ICMP requests from an MU to the switch, set the ICMP type to
8 and the code to 0.
