Miscellaneous Setting: 
 
MAC Address Age-out Time: 
Type the number of seconds that an inactive MAC 
address remains in the switch's address table. The valid range is 300~765 seconds. 
Default is 300 seconds. 
 
Max bridge transmit delay bound control: This Limits the packets queuing time. If 
enabled, packets that are queued longer than this setting will be dropped. Valid 
values for this are 1sec, 2 sec, 4 sec and off. Default is 1 seconds. 
 
NOTE: Make sure the “Max bridge transit delay bound” control is enabled before 
enabling the “Low Queue Delay Bound” option. 
 
Low Queue Delay Bound: This controls how low priority packets are queued in the 
switch. The Max Delay Time setting defines when a low priority packet is given more 
priority to send. 
 
Broadcast Storm Filter: To configure broadcast storm control, enable it and set the 
upper threshold for individual ports. The threshold is the percentage of the port's total 
bandwidth used by broadcast traffic. When broadcast traffic for a port rises above the 
threshold you set, broadcast storm control becomes active. The valid threshold 
values are 5%, 10%, 15%, 20%, 25% and 
of
f.

Priority Queue Service settings (802.1p): 
 
First Come First Service: The sequence of packets sent is dependant on the order 
in which they arrived. 
 
All High before Low: High priority packets are sent before Low priority packets. 
 
WRR:  Weighted Round Robin. 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, 5 High - 2 
Low means that the switch sends 5 high-priority packets before sending 2 low 
priority packets.
