Controller Security
5 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.
NOTE
If adding an access control entry to an ACL using the controller SNMP interface, Precedence is a required
parameter.
6 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.
7 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.
8 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.
9 From the Filters field, enter the Source Address where the packets are sourced.
10 Select a Source Wildcard/Mask from the drop-down menu.
The Source Wildcard/Mask is the size of the network or host (in mask format). The mask length
defines a match based on the Network / Host.
