Destinatio
n MAC
Address Select Any to apply the rule to all MAC addresses.
To specify a destination, select MAC/Mask to enter the destination MAC address of the packet in
valid MAC address format (six hexadecimal character pairs) and type the mask for the specified MAC
address to determine which bits a packet’s MAC address should match.
Enter “f” for each bit of the specified MAC address that the traffic’s MAC address should match. Enter
“0” for the bits of the matched traffic’s MAC address, which can be of any hexadecimal characters.
For example, if you set the MAC address to 00:13:49:00:00:00 and the mask to ff:ff:ff:00:00:00, a packet
with a MAC address of 00:13:49:12:34:56 matches this criteria. If you leave the
Mask field blank, the
Switch automatically sets the mask to ff:ff:ff:ff:ff:ff.
Layer 3
Specify the fields below to configure a layer 3 classifier.
IP Packet
Length Click Any to classify any size of packet length or manually enter a range of number (from/to) of
packet size in the field provided.
IPv4/IPv6
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.
Preceden
ce Select Any to classify traffic from any precedence or select the second option and specify an IP
Precedence (the first 3 bits 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 Protocol 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.
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.
Destinatio
n 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.
Layer 4
Specify the fields below to configure a layer 4 classifier.
Source
Socket
Number 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.
Destinatio
n Socket
Number 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.
