Figure 102.  Extended ACL Rule Configuration

4. 

Next to Sequence Number, specify a number in the range of 1 to 2147483647 to identify 
the IP ACL rule. 

You can create up to 50 rules for each ACL.

5. 

Select or specify values for one or more of the following match criteria:

•

Action

. Select the ACL forwarding action, which is one of the following: 

-

Permit

. Forwards packets which meet the ACL criteria.

-

Deny

. Drops packets which meet the ACL criteria.

•

Egress Queue

. Specify the hardware egress queue identifier used to handle all 

packets matching this ACL rule. 

•

Match Every

. Require 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

. Require 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

. Require 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

. Specify 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
