4. Set the IGMP Query Count to the number of minutes that must elapse before the switch removes 

the port from an IGMP group. This timer is started after the number of queries are missed as 
defined in the IGMP Query Count.

5. Set the IGMP Report Delay to the number of queries that must be missed before the IGMP 

Report Delay timer is started. This is used in conjunction with the IGMP Report Delay to remove 
ports from an IGMP group.

You can configure switch ports for operational parameters such as auto-negotiation, duplex mode, 
port speed and flow control. The 100Base-FX fiber ports always operate in full duplex mode and 
100 Mbps speed. Therefore, these two parameters, along with auto-negotiation, are not 
configurable on fiber ports.

To configure port operation, proceed as follows:

1. Select Device Control Menu from the Main Menu.

2. Select Port Configuration and press ENTER.

3. Select the port number to configure. 

4. In the Admin column, select ENABLED. You can also disable the port due to abnormal 

behavior or for security reasons.

5. In the Flow Control column, select ENABLED to enable flow control, or DISABLED to 

disable it. When enabled, the switch uses back pressure for half duplex and IEEE 802.3x for full 
duplex. These flow control methods can also be set directly by selecting BACK_PRESSURE or 
802.3X. Note that flow control should not be used if the port is connected to a hub.

6. In the Speed and Duplex column, select AUTO to enable Auto-negotiation for the port, or select 

1000_FULL, 1000_HALF, 100_FULL, 100_HALF, 10_FULL, or 10_HALF.

NOTE: If Auto-negotiation is not enabled, the duplex mode and port speed need to be 
configured.
