14.1.2. Tagging Mode
In the Tagging mode
,
although the 802.1Q frames are recognized, the SPR accepts
only one specific VLAN from the BSR, which it untags and passes onto the
subscriber's LAN. All other traffic from the BSR is discarded. Traffic received by
the SPR from the SDA is tagged with a specific VLAN and sent to the BSR. If the
SPR is connected to an SDA-4S/VLtag device, the SPR assigns VLANs to traffic
from each of the four SDA-4S/VLtag ports, before sending the VLAN traffic to the
BSR. In the opposite direction, the SPR accepts only traffic from these VLANs.
