DESCRIPTION

Layer 2

Specify the fields below to configure a layer 2 classifier.

VLAN

Select Any to classify traffic from any VLAN or select the second option and

 

specify the source VLAN ID in the field provided.

 

When VLAN mapping is enabled, this is the translated VLAN ID you set in the

 

VLAN Mapping Configure screen If the incoming traffic is tagged and

 

matches a VLAN mapping rule.

 

 

Priority

Select Any to classify traffic from any priority level or select the second option

 

and specify a priority level in the field provided.

 

 

Ethernet

Select an Ethernet type or select Other and enter the Ethernet type number in

Type

hexadecimal value. Refer to Table 54 on page 215 for information.

 

 

Source

 

 

 

MAC

Select Any to apply the rule to all MAC addresses.

Address

To specify a source, select the second choice and type a MAC address in valid

 

 

MAC address format (six hexadecimal character pairs).

 

 

Port

Type the port number to which the rule should be applied. You may choose one

 

port only or all ports (Any).

 

 

Destination

 

 

MAC

Select Any to apply the rule to all MAC addresses.

Address

To specify a destination, select the second choice and type a MAC address in

 

 

valid MAC address format (six hexadecimal character pairs).

 

 

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.

 

 

IP

Select an IP protocol type or select Other and enter the protocol number in

Protocol

decimal value. Refer to Table 55 on page 215 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.

 

 

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.
