M4300 Intelligent Edge Series Fully Managed Stackable Switches • Dst. In the Dst field, enter a destination IP address, using dotted-decimal notation, to be compared to a packet's destination IP address as a match criteria for the selected IP ACL rule: - If you select the IP Address radio button, enter an IP address with a relevant wildcard mask to apply this criteria. If this field is left empty, it means any. - If you select the Host radio button, the wildcard mask is configured as 0.0.0.0. If this field is left empty, it means any. The wildcard mask determines which bits are used and which bits are ignored. A wildcard mask of 0.0.0.0 indicates that none of the bits are important. A wildcard of 255.255.255.255 indicates that all of the bits are important. • Dst L4. The options are available only when protocol is set to TCP or UDP. Use the destination L4 port option to specify relevant matching conditions for L4 port numbers in the extended ACL rule. You can select either the Port radio button or the Range radio button: - If you select the Port radio button, you can either select port key from the menu or enter the port number yourself. • The destination IP TCP port names are bgp, domain, echo, ftp, ftpdata, http, smtp, snmp, Telnet, www, pop2, pop3. • The destination IP UDP port names are domain, echo, ntp, rip, snmp, tftp, time, who. Each of these values translates into its equivalent port number, which is used as both the start and end of the port range. Select Other from the menu to enter a port number. If you select Other from the menu but leave the field blank, it means any. The relevant matching conditions for L4 port numbers are as follows: • Equal. The IP ACL rule matches only if the Layer 4 destination port number is equal to the specified port number or port key. • Less Than. The IP ACL rule matches if the Layer 4 destination port number is less than the specified port number or port key. • Greater Than. The IP ACL rule matches if the Layer 4 destination port number is greater than the specified port number or port key. • Not Equal. The IP ACL rule matches only if the Layer 4 destination port number is not equal to the specified port number or port key. - If you select the Range radio button, the IP ACL rule matches only if the Layer 4 destination port number is within the specified port range. The starting port, ending port, and all ports in between are a part of the Layer 4 port range. The Start Port and End Port fields identify the first and last ports that are part of the port range. They values can range from 0 to 65535. Select Other from the menu to enter port numbers. If you select Other from the menu but leave the fields blank, it means any.
