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.

¾Disable: The stacking function is not working.

¾Master: 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.

¾Slave: 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
