Port
Specifies the port and slot whose configuration will be displayed on the page.
Port active
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.
Port enabled
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.
Access Control enabled
If this check box is selected, the IE switch does not learn unicast addresses at this port.
FD Flow Control enabled
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.
HD Flow Control enabled
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.
