This sub-menu contains ten items:
MAC Address Ageing Time:
MAC address table refresh time setting. Input the number of seconds that an inactive MAC address
remains in the SGSW-2620's MAC address table. The available range is 0, 300~765 seconds. De-
fault mode is 300 seconds.
Broadcast Storm Filter mode:
Configure the broadcast storm filter mode. The available threshold values are 5%, 10%, 15%, 20%,

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 mode 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 disable or enable this
function.
Low Queue Max Delay Time:
To set the time that low priority packets queuing on SGSW-2620. Default Max Delay Time is 255ms.
The valid range is 1~255 ms.
Collisions Retry Forever:
Disable – In half duplex, if happens collision, the SGSW-2620 will retry 48 times and then drop frame.
Enable – In half duplex, if happens collision, the SGSW-2620 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 this function.
IP Stacking Group ID (0...65535):
Assign the stacking group ID. The switches must assign the same stacking group ID and can stack
together as a group.
IP Stacking Mode:
Disable or enable 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 interface of
SGSW-2620
Disable: The stack function is not working.
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.
Slave:
Besides the master switch, rest of the switches are called slave switch in stacking group. When the
stacking group is set up, only can configure the slave switches through the master switch.
After setup completed, press "ESC" and choose "Save" to save the current configuration.
