MAC Mask Enter 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 source 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.
Exclude Select this option to exclude the packets that match the specified criteria from this classifier.
Destination
Address Select the check box and enter the source IP address in dotted decimal notation. A blank
source IP address means any source IP address.
Subnet Mask This field is available only when you select IP in the Ether Type field.
Enter the source subnet mask.
Prefix Length This field is available only when you select IPV6 in the Ether Type field.
Enter the source prefix length.
See the IPv6 Appendix for more IPv6 information.
Port Range If you select TCP or UDP in the IP Protocol field, select the check box and enter the port numbers
of the source.
MAC Select the check box and enter the source MAC address of the packet.
MAC Mask Enter 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 source 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.
Exclude Select this option to exclude the packets that match the specified criteria from this classifier.
Others
Service This field is available only when you select IP or IPv6 in the Ether Type field.
This field simplifies classifier configuration by allowing you to select a predefined application.
When you select a predefined application, you do not configure the rest of the filter fields.
IP Protocol This field is available only when you select IP or IPv6 in the Ether Type field.
Select this option and select the protocol (service type) from TCP, UDP, ICMP or IGMP. If you
select User defined, enter the protocol (service type) number.
DHCP This field is available only when you select IP in the Ether Type field.
Select this option and select a DHCP option.
If you select Vendor Class ID (DHCP Option 60), enter the Vendor Class Identifier (Option 60) of
the matched traffic, such as the type of the hardware or firmware.
If you select Client ID (DHCP Option 61), enter the Identity Association IDentifier (IAD Option 61)
of the matched traffic, such as the MAC address of the device.
If you select User Class ID (DHCP Option 77), enter a string that identifies the user’s category or
application type in the matched DHCP packets.
If you select Vendor Specific Info (DHCP Option 125), enter the vendor specific information of
the matched traffic, such as the product class, model name, and serial number of the device.
IP Packet
Length
This field is available only when you select IP in the Ether Type field.
Select this option and enter the minimum and maximum packet length (from 46 to 1500) in the
fields provided.
