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.
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.
• IGMP Type. If you specify the IGMP type, the IP ACL rule matches the specified
IGMP message type. Possible values are in the range 0 to 255. If this field is left
empty, it means any.
• ICMP. Select either the ICMP Type or ICMP Message radio button:
- If you select the ICMP Type radio button, note the following:
• The ICMP Type and ICMP Code fields are enabled only if the protocol is
ICMP. Use these fields to specify a match condition for ICMP packets:
• The IP ACL rule matches the specified ICMP message type. Possible type
numbers are in the range from 0 to 255.
• If you specify information in the ICMP Code field, the IP ACL rule matches the
specified ICMP message code. Possible values for the code can be in the
range from 0 to 255.
• If these fields are left empty, it means any.
- If you select the ICMP Message radio button, select the type of the ICMP
message to match with the selected IP ACL rule. Specifying a type of message
implies that both the ICMP type and ICMP code are specified. The ICMP
message is decoded into the corresponding ICMP type and ICMP code within the
ICMP type.
