20.2.1 Viewing and Editing Classifier Configuration
To view a summary of the classifier configuration, scroll down to the summary table at the bottom
of the Classifier screen. To change the settings of a rule, click a number in the Index field.
Note: When two rules conflict with each other, a higher layer rule has priority over lower
layer rule.
IP
Protocol
Select an IP protocol type or select Other and enter the protocol number in decimal value. Refer
to Table 66 on page 159 for more information.
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.
IPv6 Next
Header
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.
Source
IP
Address/
Address
Prefix
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.
Socket
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. Refer to Table 67 on page 160 for more
information.
Destination
IP
Address/
Address
Prefix
Enter a destination IP address in dotted decimal notation.
Specify the address prefix by entering the number of ones in the subnet mask.
Socket
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. Refer to Table 67 on page 160 for more
information.
Add Click Add to insert the entry in the summary table below and 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.
Cancel Click Cancel to reset the fields back to your previous configuration.
Clear Click Clear to set the above fields back to the factory defaults.
