Defining Access Control Lists 65 ■ Selection ACL - Selects an existing MAC-based ACL to which rules are to be added. ■ Create ACL - Defines a new user-defined MAC-based Access Control List. Add Rules to ACL ■ Priority - Sets the rule priority, which determines which rule is matched to a packet on a first-match basis. The possible field values are 1-2147483647. ■ Source MAC Address - Matches the source MAC address to which packets are addressed to the rule. ■ Source Mask - Defines the source MAC Address wildcard mask. Wildcards are used to mask all or part of a source MAC address. Wildcard masks specify which bits are used and which are ignored. A wildcard mask of FF:FF:FF:FF:FF:FF indicates that no bit is important. A wildcard of 00.00.00.00.00.00.00 indicates that all bits are important. For example, if the source MAC address is 00:AB:22:11:33:00 and the wildcard mask is 00:00:00:00:00:FF, the first five bytes of the MAC are used, while the last byte is ignored. For the source MAC address 00:AB:22:11:33:00, this wildcard mask matches all MAC addresses in the range 00:AB:22:11:33:00 to 00:AB:22:11:33:FF. ■ Destination MAC Address - Matches the destination MAC address to which packets are addressed to the rule. ■ Destination Mask - Defines the destination MAC Address wildcard mask. Wildcards are used to mask all or part of a destination MAC address. Wildcard masks specify which bits are used and which are ignored. A wildcard mask of FF:FF:FF:FF:FF:FF indicates that no bit is important. A wildcard mask of 00.00.00.00.00.00 indicates that all bits are important. For example, if the destination MAC address is 00:AB:22:11:33:00 and the wildcard mask is 00:00:00:00:00:FF, the first five bytes of the MAC are used, while the last byte is ignored. For the destination MAC address 00:AB:22:11:33:00, this wildcard mask matches all MAC addresses in the range 00:AB:22:11:33:00 to 00:AB:22:11:33:FF. ■ VLAN ID - Matches the packet's VLAN ID to the rule. The possible field values are 1 to 4093. ■ CoS - Classifies traffic based on the CoS tag value. ■ CoS Mask - Defines the CoS mask used to classify network traffic.
