VLAN ID Remarking
SM supports the ability to re-mark the VLAN ID on both upstream and downstream VLAN frames at the
Ethernet interface. For instance, a configuration can be added to re-mark VLAN ID ‘x’ to VLAN ID ‘y’ as
shown in
. AP does not support VLAN ID remarking.
Table 12 VLAN Remarking Example
VLAN frame direction
Remarking
Upstream
SM receives VLAN ID ‘x’ frame at the Ethernet interface, checks the
configuration and re-marks to VLAN ID ‘y’. So VLAN ID ‘y’ frame comes
out of AP’s Ethernet interface. When SM re-marks, a dynamic entry in
VLAN membership table for ‘y’ is added to allow reception of VLAN ID
‘y’ downstream packet.
Downstream
AP receives VLAN ID ‘y’ frame at the Ethernet interface and sends to SM.
SM accepts the frame as it has an entry in the membership table and re-
marks to VLAN ID ‘x’. This reverse re- marking is necessary because the
downstream devices do not know of re-marking and are expecting VLAN
‘x’ frames. This remarking is done just before sending the packet out on
Ethernet interface.
802.1P Remarking
AP/BHM and SM/BHS allow re-marking of 802.1p priority bits for the frames received at the Ethernet
interface. Priority bits are not re-marked for the packets sent out of Ethernet interface (reverse
direction).
Configuration must be added at SM/BHS for upstream frames and at AP/BHM for downstream frames.
VLAN Priority Bits configuration
VLAN Priority Bits Configuration feature allows the user to configure the three 802.1p bits upon
assigning VLAN to an ingress packet. The priority bits configuration is available for:
•
Default Port VID
•
Provider VIDs
•
MAC Address mapped Port VID
•
Management VID
Default Port VID
This VID is used for untagged frames and will correspond to the Q-Tag for 802.1Q frames (if VLAN
Port Type is Q), or the C-Tag for 802.1ad frames (if the VLAN Port Type is QinQ).
The priority bits used in the Q-tag/C-tag are configurable.
