Qos Policy: High Priority Levels:

0~7 priority level can map to high or

low queue. When the VLAN Tag number of a frame is mapping the

priority level of the port, and this frame can have high priority.(This QoS

Policy is for global Switch, not for any single port)

Protocol Enable Setting :

Enable Spanning Tree Protocol :

Default recommend to enable STP

Enable Internet Group Multicast Protocol:

enable IGMP protocol

IGMP Query Mode:

Recognize different Query from client or server to

decide which Queryer will be the first priority, they are three mode as

follow:

Auto Mode

: Choose the indicated Switch, which has the smallest IP

address will be set for the IGMP Queryer.

Enable Mode

: Enable one of Switch to be the IGMP Queryer.

Disable Mode

: Disable the other Switches to be the IGMP Queryer.

VLAN Operation Mode:
