GS752TXS and GS728TXS Smart Switches 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. Specifies the hardware egress queue identifier used to handle all packets matching this ACL rule. • 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. 235
