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
1 to 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.
