removed) and a single-tagged packet will leave untagged.

 

Pri-0 ~ 7: set the default VLAN priority level.

 

no Stack/Stack/TLS: disable N:1 VLAN stacking / enable N:1 VLAN

 

stacking (our system adds the default VLAN tag to all the incoming frames

 

through this port) / enable TLS (transparent LAN service) so that this bridge

 

port becomes VLAN transparent (refer to DSL Forum, TR-101). A

 

pre-configured S-Tag is used to encapsulate TLS traffic going through this

 

port. That is, an S-Tag (PVID here) will be added to all the upstream frames

 

received on this port, and the C-Tags will be the original tags of these

 

frames (no C-Tag for untagged incoming frames). On the other hand, the

 

S-tag will be removed from all the downstream (outgoing) frames.

 

Note: When an untagged frame enters the IDL-2402, it is assigned the

 

default PVID of the ingress (incoming) bridge port and become a

 

single-tagged frame no matter VLAN stacking is enabled or not.

 

 

 

Set Ingress ON: check if the VID of the incoming frame is in the member set. If

Ingress

not in the member set, block the frame.

 

 

Set Ingress OFF: Ingress filter disabled.

 

 

AccFrm

Click on the drop-down list and select to accept ALL Frame, only VLAN tagged

frame, or only Untagged frame.

 

 

 

 

ON/OFF: to enable/disable isolation. When port isolation is enabled, packets

Isolation

received from a line bridge port (including trunk interface configured as

user-link) cannot be forwarded to any other line bridge port even for

 

 

broadcasting.

 

 

 

Click on the drop-down list and select the priority-forcing mode. Options are:

 

Disabled: Reserve the original priority of all packets.

 

Ingress: Force applying the default VLAN priority value to all the packets

Priority Force

received on this bridge port (so this rule will work on all the

member-set of this bridge port).

 

Egress: Force the priority value of all packets sent out from this bridge port’s

 

default VLAN to be the default VLAN priority (so this rule only works

 

on default VLAN of this bridge port).

 

Both: Combine the rules of Ingress and Egress.
