Chapter 5: Local Management
Advertised Ability (Selectable)
During auto-negotiation, the port “tells” the device at the other end of the segment what its capabilities are. The capabilities of a port are 10BASE-T, 10BASE-TFD (full duplex mode), 100BASE-TX and 100BASE-TXFD (full duplex mode, ports 15 and 16 only). In normal operation, with all capabilities enabled, the port “advertises” that it has the ability to operate in any mode. The Network Manager may choose to set up the port so that only a portion of the available capabilities are advertised and the others are disabled. For example, only 100BASE-TX and 100BASE-TXFD (ports 15 and 16 only) might be enabled so that only devices that operate at 100 Mbps can communicate with that port. Section 5.19.3 describes how to enable or disable advertised modes.
Flow Control Admin Status (Selectable)
Enabling this setting controls whether or not the switch will block traffic on all ports when there is excessive traffic for the switch to process. This will clear the ports and allow the switch to process the current frame information. Section 5.19.4 explains how to enable or disable this option.
5.19.1 Configuring the Ports
In normal operation, a 6H122-16 interface automatically establishes a link with the device at the other end of the segment and no user setup is required. Section 5.19.2 and Section 5.19.3 provide instructions for manually configuring the interface.
5.19.2 Setting the Operational Mode
Use this field to set the active technology. This field steps between Auto-Negotiation, 10BASE-T, 10BASE-TFD (full duplex), 100BASE-TX, and 100BASE-TXFD (full duplex, ports 15 and 16 only). If Auto-Negotiation is selected, the port automatically sets the active technology. To manually set the active technology through Local Management, proceed as follows:
1.Use the arrow keys to highlight the Desired Oper. Mode field.
2.Use the SPACE bar to select the desired mode. Press ENTER. If any mode other than auto-negotiation is selected, the port only operates in the chosen mode and auto-negotiation is disabled.
