time period. If the Access List Trap Flag is also enabled, this will cause periodic traps 
to be generated indicating the number of times this rule was hit during the current 
report interval. A fixed five-minute report interval is used for the entire system. A trap 
is not issued if the ACL rule hit count is zero for the current interval. This field is only 
supported for a Deny action. 

Match Every. Requires a packet to match the criteria of this ACL. Select True or 

False from the drop down menu. Match Every is exclusive to the other filtering rules, 
so if Match Every is True, the other rules on the screen are not available.

Protocol Type. Requires a packet’s protocol to match the protocol listed here. Select 

a type from the drop down menu or enter the protocol number in the available field.

Src IP Address. Requires a packet’s source IP address to match the address listed 

here. Type an IP Address in the appropriate field using dotted-decimal notation. The 
address you enter is compared to a packet's source IP Address. 

Src IP Mask. Specifies the source IP address wildcard mask. Wild card masks 

determines which bits are used and which bits are ignored. A wild card mask of 
255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that 
all of the bits are important. Wildcard masking for ACLs operates differently from a 
subnet mask. A wildcard mask is in essence the inverse of a subnet mask. For 
example, to apply the rule to all hosts in the 192.168.1.0/24 subnet, you type 
0.0.0.255 in the Source IP Mask field. This field is required when you configure a 
source IP address.

Src L4 Port. Requires a packet’s TCP/UDP source port to match the port listed here. 
Click Complete one of the following fields:

Source L4 Keyword: Select the desired L4 keyword from a list of source ports on 

which the rule can be based.

Source L4 Port Number: If the source L4 keyword is Other, enter a user-defined 

Port ID by which packets are matched to the rule.

Dst IP Address. Requires a packet’s destination port IP address to match the 

address listed here. Enter an IP Address in the appropriate field using dotted-decimal 
notation. The address you enter is compared to a packet's destination IP Address. 

Dst IP Mask. Specifies the destination IP address wildcard mask. Wild card masks 

determines which bits are used and which bits are ignored. A wild card mask of 
255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that 
all of the bits are important. Wildcard masking for ACLs operates differently from a 
subnet mask. A wildcard mask is in essence the inverse of a subnet mask. For 
example, to apply the rule to all hosts in the 192.168.1.0/24 subnet, you type 
0.0.0.255 in the Source IP Mask field. This field is required when you configure a 
source IP address.

Dst L4 Port. Requires a packet’s TCP/UDP destination port to match the port listed 

here. Complete one of the following fields:

Destination L4 Keyword: Select the desired L4 keyword from a list of destination 

ports on which the rule can be based. 

Destination L4 Port Number: If the destination L4 keyword is Other, enter a 

user-defined Port ID by which packets are matched to the rule.
