Configuring Port Operation
Configuring and Monitoring the Switch 10-9
To configure IGMP operation, proceed as follows:
1. Select Device Control Menu from the Main Menu.
2. Select IGMP Configuration and press ENTER.
3. Set the IGMP Status to ENABLED. This enables the switch to monitor network traffic to
determine which hosts want to receive multicast traffic. Default is DISABLED.
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.
10.14 CONFIGURING PORT OPERATION
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 these 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.
