Figure 4-50  Port configuration 
Specifies the port and slot whose configuration will be displayed on the page. 
 
With this check box, you can set the "Link Up" and "Link Down" statuses even for ports that 
are turned off ("Port enabled" without a check mark). If the check box is selected, the "Link 
Up" status is indicated to the communication partner even for a port that is turned off. 
Select this check box to enable the port for data traffic. If this check box is not selected, the 
"Link Up" status is indicated to the communications partner of this port anyway. The 
connection status can be changed with the "Port active" check box. 
If this check box is selected, the IE switch does not learn unicast addresses at this port. 
Enables / disables flow control for the full duplex mode. Flow control is, however, only 
effective if the port operates in full duplex mode. If flow control is enabled but not in effect, 
the set check mark disappears again after the screen is refreshed; it does not, however, 
need to be set again if flow control comes into effect. 
Enables / disables flow control for the half duplex mode. Flow control is, however, only 
effective if the port operates in half duplex mode. 
 
Note 
If the port configuration is set (fixed) to ring ports, correct operation of the redundancy 
function is no longer possible. For correct operation, the ring ports must be in
 full duplex 
mode. It is advisable to set the ring ports to autonegotiation.
