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.
