queuing time in the switch. If enabled, the packets exceeding the
queue will be dropped. Valid values are 1, 2 or 4 seconds and Off.
The default is 1 second.
Broadcast Storm Filter - This option is used to configure the
broadcast storm control. It must be enabled and then the upper
threshold must be set for the individual ports. The threshold is the
percentage of the port's total bandwidth used by broadcast traffic.
When the broadcast traffic for a port rises above the threshold that
has been set, broadcast storm control becomes active. The valid
threshold value is 5%, 10%, 15%, 20%, 25% and Off.
First Come First Service - The sequence of packets sent depends
on the arrival order.
All High before Low - The high priority packets are sent before the
low priority packets.
Weighted Round Ratio - Select the preference given to packets in
the switch's high-priority queue. These options represent the
number of high priority packets sent before one low priority packet is
sent. For example, 2 High: 1 Low means that the switch sends 2
high priority packets before sending 1 low priority packet.
Enable Delay Bound – This setting limits the low priority packets
queuing time in switch. The Default Max Delay Time is 255ms. If
the low priority packet that stays in switch exceeds the Max Delay
Time, it will be sent. The valid range is 1~255 ms.
QoS Policy: High Priority Levels – There are 0~7 priority levels
that can be mapped to high or low queue. When sending packets,
different priority Levels in VLAN Tag can be selected.
NOTE: Make sure Max bridge transit delay bound control is
enabled before enabling Delay Bound.
Enable Spanning Tree Protocol – The default is Disabled. The
