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.
• Src L4. The options are available only when the protocol is set to TCP or UDP. Use the
source 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 enter the port number yourself
or select one of the following protocols from the menu:
• The source IP TCP port protocols are domain, echo, ftp, ftpdata, www-http,
smtp, telnet, pop2, pop3, and bgp.
• The source IP UDP port protocols are domain, echo, snmp, ntp, rip, time,
who, and tftp.
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. IP ACL rule matches only if the Layer 4 source port number is equal to
the specified port number or port protocol.
• Less Than. IP ACL rule matches if the Layer 4 source port number is less
than the specified port number.
• Greater Than. IP ACL rule matches if the Layer 4 source port number is
greater than the specified port number.
• Not Equal. IP ACL rule matches only if the Layer 4 source port number is not
equal to the specified port number or port protocol.
- If you select the Range radio button, the IP ACL rule matches only if the Layer 4
source 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. The values can range from 0 to 65535.
You can either enter the port range yourself or select one of the following
protocols from the menu:
• The destination IP
TCP port protocols are domain,
echo, ftp, ftpdata,
www-http, smtp, telnet, pop2, pop3, and bgp.
• The destination IP UDP port protocols are domain, echo, snmp, ntp, rip,
time, who, and tftp.
Each of these values translates into its equivalent port number, which is used as
both the start and end of the port range.
