62 CHAPTER 4: MANAGING DEVICE SECURITY Modify ■ Priority - Indicates the rule priority, which determines which rule is matched to a packet on a firstmatch basis. ■ Source MAC Address - Matches the source MAC address to which packets are addressed to the ACE. ■ Source Mask - Indicates the source MAC Address wildcard mask. Wildcards are used to mask all or part of a source address by specifying 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 E0:3B:4A:C2:CA:E2 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 E0:3B:4A:C2:CA:E2, this wildcard mask matches all MAC addresses in the range E0:3B:4A:C2:CA:00 to E0:3B:4A:C2:CA:FF. ■ Destination MAC Address - Matches the destination MAC address to which packets are addressed to the ACE. ■ Destination Mask - Indicates the destination MAC Address wildcard mask. Wildcards are used to mask all or part of a destination address by specifying 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 E0:3B:4A:C2:CA:E2 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 E0:3B:4A:C2:CA:E2, this wildcard mask matches all MAC addresses in the range E0:3B:4A:C2:CA:00 to E0:3B:4A:C2:CA:FF. ■ VLAN ID - Matches the packet's VLAN ID to the ACE. 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. ■ Ethertype - Provides an identifier that differentiates between various types of protocols. ■ Action - Indicates the ACL forwarding action. 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:

■
Priority
— Indicates the rule priority, which determines which rule is
matched to a packet on a firstmatch basis.
■
Source MAC Address
— Matches the source MAC address to which
packets are addressed to the ACE.
■
Source Mask
— Indicates the source MAC Address wildcard mask.
Wildcards are used to mask all or part of a source address by
specifying 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 E0:3B:4A:C2:CA:E2 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
E0:3B:4A:C2:CA:E2, this wildcard mask matches all MAC addresses in
the range E0:3B:4A:C2:CA:00 to E0:3B:4A:C2:CA:FF.
■
Destination MAC Address
— Matches the destination MAC address
to which packets are addressed to the ACE.
■
Destination Mask
— Indicates the destination MAC Address
wildcard mask. Wildcards are used to mask all or part of a destination
address by specifying 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
E0:3B:4A:C2:CA:E2 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 E0:3B:4A:C2:CA:E2, this wildcard mask
matches all MAC addresses in the range E0:3B:4A:C2:CA:00 to
E0:3B:4A:C2:CA:FF.
■
VLAN ID
— Matches the packet's VLAN ID to the ACE. 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.
■
Ethertype
— Provides an identifier that differentiates between
various types of protocols.
■
Action
— Indicates the ACL forwarding action. 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:
