Support Notes
Click Networking Setting -> QoS to open the screen as shown next. Use this
screen to enable or disable QoS, and select to have the ZyXEL Device
automatically assign priority to traffic according to the IEEE 802.1p priority
level, IP precedence and/or packet length.
IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to
identify the VLAN membership of a frame across bridges. A VLAN tag includes
the 12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame
with a specific VLAN and provides the information that devices need to
process the frame across the network. IEEE 802.1p specifies the user priority
field and defines up to eight separate traffic types. The following table
describes the traffic types defined in the IEEE 802.1d standard (which
incorporates the 802.1p).

7. Network Management Using SNMP

 ZyXEL SNMP Implementation
ZyXEL currently includes SNMP support in some AMG1302-T10B
/AMG1202-T10B routers. It is implemented based on the SNMPv1, so it will be
able to communicate with SNMPv1 NMSs. Further, users can also add
ZyXEL's private MIB in the NMS to monitor and control additional system
variables. The ZyXEL's private MIB tree is shown in figure 3. For SNMPv1
operation, ZyXEL permits one community string so that the router can belong
to only one community and allows trap messages to be sent to only one NMS
manager.
