LABEL DESCRIPTION
Layer 3
Specify the fields below to configure a layer 3 classifier.
DSCP Select Any to classify traffic from any DSCP or select the second option and specify a DSCP
(DiffServ Code Point) number between 0 and 63 in the field provided.
IPv4/IPv6
Precedenc Select Any to classify traffic from any precedence or select the second option and specify an IP
e Precedence (the first 3 bits of of the 8-bit ToS field) value between 0 and 7 in the field provided.
ToS Select Any to classify traffic from any ToS or select the second option and specify Type of Service
(the last 5 bits of the 8-bit ToS field) value between 0 and 255 in the field provided.
IP Select an IPv4 protocol type or select Other and enter the protocol number in decimal value.
Protocol Refer to Table 73 on page 176
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 Select an IPv6 protocol type or select Other and enter an 8-bit next header in the IPv6 packet.
Header 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 Enter a source IP address in dotted decimal notation.
Address/
Specify the address prefix by entering the number of ones in the subnet mask.
Address
Prefix
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
Note: You must select either UDP or TCP in the IP Protocol field before you configure the socket
Number
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
information.
Destination
IP Enter a destination IP address in dotted decimal notation.
Address/
Specify the address prefix by entering the number of ones in the subnet mask.

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
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.
