Configure an ACE (Access Control Entry) on this page.
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. Note that different parameter options
are displayed depending on the frame type selected.

Configuration page:
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 a
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 127.
Policy Bitmask: When "Specific" is selected for the policy filter, you can enter a specific policy bitmask. The
allowed range is 0x0 to 0x7f. 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.
