Opening a dual tab

If you have ports with redundant connectors, a Dual tab appears. This tab allows
you to define which of the connectors is the Primary connector.
To open the Dual tab:

314723-D Rev 01
On the device view, select a port or multiple ports.
From the Device Manager menu bar, choose Edit > Port.
The Port dialog box opens with the Interface tab displayed.
Click the Dual tab.
Description
Indicates whether or not the port is locked. When locked, the
port configuration cannot be changed. To lock or unlock a port,
select Edit > Security > Port Lock.
If rcUnknownMacDiscard is set to True, then a packet with an
unknown source MAC address is dropped on that port, and
other ports then will discard any packets with this MAC
address in the destination field. For example, suppose
11:22:33:44:55:66 is an unknown source MAC. Packets with
source MAC 11:22:33:44:55 coming from this port are
discarded; furthermore, packets with destination MAC
11:22:33:44:55:66 coming from other ports are also discarded,
unless this address is later learned on another port or the
restriction ages out.
Note: You cannot set the unknown-mac-discard
lock-autolearn-mac disable parameter when autolearn is
disabled.
Used to indicate whether this interface should forward direct
broadcast traffic.
