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 last two bits are ignored.
•Destination — Destination MAC Address.
—MAC Address — Matches the destination MAC Address to which packets are addressed to the rule.
—Mask — Indicates 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 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 E0:00:AB:22:11:33:00 and the wildcard mask is 00:00:00:00:00:FF, the last two bits are ignored.
•VLAN ID — Matches the packet’s VLAN ID to the rule. The possible field values are
1to 4093.
•CoS — Classifies traffic based on the CoS tag value.
•CoS Mask — Defines the Cost of Service mask.
•Ether Type — Provides an identifier that differentiates between various types of protocols.
•Action — Indicates the ACL forwarding action. In addition, the port can be shut down, a trap can be sent to the network administrator, or packet is assigned rate limiting restrictions for forwarding. The options are as follows:
—Permit — Forwards packets which meet the ACL criteria.
—Deny — Drops packets which meet the ACL criteria.
—Shutdown — Drops packet that meet the ACL criteria, and disables the port to which the packet was addressed. Ports are reactivated from the Port Configuration Page.
