Description

Ingress Port

Select the ingress port for which this ACE applies.

All: The ACE applies to all port.

Port n: The ACE applies to this port number, where n is the number of the switch

port.

Policy Filter

Specify the policy number filter for this ACE.

Any: No policy filter is specified. (policy filter status is "don't-care".)

Specific: If you want to filter a specific policy with this ACE, choose this value. Two

field for entering an policy value and bitmask appears.

Policy Value

When "Specific" is selected for the policy filter, you can enter a specific policy value.

The allowed range is 0 to 255.

Policy Bitmask

When "Specific" is selected for the policy filter, you can enter a specific policy bitmask.

The allowed range is 0x0 to 0xff. Notice the usage of bitmask, if the binary bit value

is "0", it means this bit is "don't-care". The real matched pattern is [policy_value &

policy_bitmask]. For example, if the policy value is 3 and the policy bitmask is 0x10(bit

0 is "don't-care" bit), then policy 2 and 3 are applied to this rule.

Frame Type

Select the frame type for this ACE. These frame types are mutually exclusive.

Any: Any frame can match this ACE.

Ethernet Type: Only Ethernet Type frames can match this ACE. The IEEE 802.3

describes the value of Length/Type Field specifications to be greater than or equal to

1536 decimal (equal to 0600 hexadecimal).

ARP: Only ARP frames can match this ACE. Notice the ARP frames won't match the

ACE with ethernet type.
