4.10.4.9.3 Active Rule Type
The Active Rule Type parameter defines which of the Filtering Rules List is used.
The available options are Layer 2 and Layer 3/4.
The default option is Layer 2.
4.10.4.9.4 Admin Status
The Admin Status parameter defines whether the filtering mechanism is enabled
or disabled.
The default option is Disabled.
4.10.4.9.5 Default Action
The Default Action parameter defines the action to be taken for a frame matching
any of the applicable Filtering Rules: Deny (discard) or Allow (forward).
If the Default Action is Allow, all frames matching any of the applicable Filtering
Rules will be forwarded, and all other frames will be discarded.
If the Default Action is Deny, all frames matching any of the applicable Filtering
Rules will be discarded, and all other frames will be forwarded.
The default option is Deny.
The menu also enables viewing and resetting the Non Matching Counter, which
displays the total number of frames that did not match any of the applicable
Filtering Rules, accumulated since the last reset. The counter will be reset also
after changing the Active Rule Type or disabling the Admin Status.
NOTE
L3/L4 Filtering Rules are applicable only to IP packets. If the Default Action is Allow, non-IP packets
will be forwarded although they do not match any of the applicable Forwarding Rules.
NOTE

Broadcasts and Management frames received from the network, whose destination is the NPU,
are never filtered.
 ARP messages will be forwarded automatically if the following conditions are met:
1. Active Rule Type is L3/L4.
2. The L3/L4 Filtering Rules List includes at least one L4 Filtering Rule (a defined protocol).
3. The Default Action is Allow.
This is applicable for both interfaces.
