Operation and Administration
Show VLAN ID Relaying List
The Show VLAN Relaying option displays the values of the VLAN IDs
included in the VLAN Relaying List.
NOTES:
If the VLAN ID Relaying List is empty and the VLAN Relaying Support is Enabled, then all
data frames relayed from the wireless link are discarded.
If VLAN Relaying Support and VLAN Forwarding Support are both enabled, then all VLAN
IDs configured in the Relaying List must also be configured in the Forwarding List.
VLAN Traffic Priority
Each packet to be transmitted to the wireless link is transferred to one of
three queues: Low, Mid and High. Packets in the High queue have the
highest priority for transmission, and those in the Low queue have the
lowest priority.
BreezeACCESS Subscriber and Access units support layer 2 traffic
prioritization according to the IEEE 802.1p standard. The priority field in
the 802.1Q header tag can have a value in the range 0-7. This value
determines the relative priority of the packet.
Packets received from the Ethernet port that have a Priority higher than
the value of the VLAN Priority Threshold are routed to the Mid queue.
Since the system also supports layer 3 prioritization, based on ToS,
packets with precedence in the ToS field higher than the value of the ToS
Precedence Threshold parameter are also routed to the Mid queue. This is
applicable to both tagged and untagged frames.
All other packets received from the Ethernet port are routed to the Low
queue.
Control and wireless management frames generated in the unit are routed
to the High queue.
Any frame coming from the Ethernet port, which is meant to reach another
BreezeACCESS unit via the wireless port, is sent to the High queue,
regardless of the priority configuration.
The VLAN Traffic Priority menu provides the following parameters:
