DESCRIPTION
Select an IPv4 protocol type or select Other and enter the protocol number in decimal value.
You may select Establish Only for TCP protocol type. This means that the Switch will pick out the
packets that are sent to establish TCP connections.
Select an IPv6 protocol type or select Other and enter an 8-bit next header in the IPv6 packet. The
Next Header field is similar to the IPv4 Protocol field. The IPv6 protocol number ranges from 1 to 255.
You may select Establish Only for TCP protocol type. This means that the Switch will identify packets
that initiate or acknowledge (establish) TCP connections.
Enter a source IP address in dotted decimal notation.
Specify the address prefix by entering the number of ones in the subnet mask.
A subnet mask can be represented in a 32-bit notation. For example, the subnet mask "255.255.255.0"
can be represented as "11111111.11111111.11111111.00000000", and counting up the number of
ones in this case results in 24.
Enter a destination IP address in dotted decimal notation.
Specify the address prefix by entering the number of ones in the subnet mask.
Select Any to apply the rule to all TCP/UDP protocol port numbers or select the second option and
enter a TCP/UDP protocol port number.
Note: You must select either UDP or TCP in the IP Protocol field before you configure the
socket numbers.
Select Any to apply the rule to all TCP/UDP protocol port numbers or select the second option and
enter a TCP/UDP protocol port number.
Note: You must select either UDP or TCP in the IP Protocol field before you configure the
socket numbers.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it
is turned off or loses power, so use the Save link on the top navigation panel to save your changes to
the non-volatile memory when you are done configuring.
Click Clear to clear the fields to the factory defaults.
Click Cancel to not save the configuration you make and return to the last screen.
