38
number of seconds that an inactive MAC address remains in the switch’s address
table. The valid range is 0, 300~765 seconds. Default is 300 seconds.
Broadcast Storm Filter mode:
configure the broadcast storm filter mode. The
valid threshold values are 5%, 10%, 15%, 20%, 25%, and N/A. The port will be
block cause of broadcast packet is over the percentage of traffic.
Max Bridge Transmit Delay Bound:
Limit the packets queuing time in switch. If
enable, the packets queued exceed will be drop. Press
Space
key to set the time.
This valid value are 1sec, 2sec, 4sec and off. Default is off.
Low Queue Delay Bound:
Limit the low priority packets queuing time in switch. If
enable, the low priority packet stays in switch exceed Low Queue Max Delay Time,
it will be sent. Press
Space
key to enable or disable this function.
Low Queue Max Delay Time:
To set the time that low priority packets queuing in
switch. Default Max Delay Time is 255ms. The valid range is 1~255 ms.
NOTE:
Make sure of “Max bridge transit delay bound control” is enabled before enable
Low Queue Delay Bound, because Low Queue Delay Bound must be work under “Max
bridge transit delay bound control” is enabled situation.
Collisions Retry Forever:
Disable – In half duplex, if happens collision, the
switch will retry 48 times and then drop frame. Enable – In half duplex, if happens
collision, the switch will retry forever
Hash Algorithm:
This Hash Algorithm is for hardware maintain on MAC table
calculation. Provide CRC or Direct Map
IFG compensation:
Disable or Enable
IP Stacking Group ID (0…65535):
assign the stacking group ID. The switches
must assigned the same stacking group ID to be stacked as a group.
IP Stacking Mode:
enabling/disabling the stacking function. There are three
stacking modes. Any port on the switch can be used to stack. To configure the
switch in stacking group, please use the Web GUI configuration interface.
¾
Disable:
The stacking function is not working.
¾
Master:
There must have a leader switch to control all other switches in
stacking group. You can only assign one switch to be the master switch in
one stacking group. When the stacking group is set up, the master switch will
control all switches in the stacking group.
¾
Slave:
besides the master switch, rest of the switches are called slave switch
in stacking group. When the stacking group is set up, you can only configure
