you can change the status of each port in this page.

    1.state: you can enable or disable this port.

    2.auto negotiation: you can set auto negotiation mode as auto, nway (specify the speed/duplex on this port and enable auto-negotiation) or force of each port.

    3.speed: you can set 100 or 10mbps speed on port1～port24.

    and set 1000/100/10mbps on port25～port26 (gigabit ethernet switch) or 100/10mbps on port25～port26 (fast ethernet switch).

    4.duplex: you can set each port as full-duplex or half-duplex mode.

    5.flow control:

    full: you can set flow control function is enable or disable in full duplex mode.

    half: you can set backpressure is enable or disable in half duplex mode.

    6.rate control: this switch, port1 ～ port 24, supports by-port ingress and egress rate control. for example, assume port 1 is 10mbps, users can set it’s effective egress rate is 1mbps, ingress rate is 500kbps. this switch will perform flow control or backpressure to confine the ingress rate to meet the specified rate.

    ingress: type the port effective ingress rate. the valid range is

    0～1000. the unit is 100k

    0: disable rate control

    1～1000: valid rate value

    egress: type the port effective egress rate. the valid range is 0～1000. the unit is 100k.

    0: disable rate control

    1～1000: valid rate value.

    7.port security: a port in security mode will be “locked” without permission of address learning. only the incoming packets with smac already existing in the address table can be forwarded normally. you can disable the port from learning any new mac addresses then use the static mac addresses screen to define a list of mac addresses that can use the secure port. enter the settings, then click apply button to changes on this page.
