An ACE consists of several parameters. These parameters vary according to the frame type that you
select. First select the ingress port for the ACE, and then select the frame type. Different parameter
options are displayed depending on the frame type selected. A frame that hits this ACE matches the
configuration that is defined here.
Ingress Port

When Specific is selected for the policy filter, you can enter a
specific policy value. The allowed range is 0 to 255.

Policy Bitmask
Setting Description
Factory
Default
0x0 ~ 0xff
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.
