MDI Specifies the crossover mode of the port, either MDI (normal) or MDI-X (crossover).
To connect two ports of the same configuration (MDI to MDI or MDI-X to MDI-X), an Ethernet
crossover cable is needed to cross over the transmit and receive signals in the cable, so that they are
matched at the connector level. Otherwise, you can select Auto and let the ports themselves detect the
required cable connection type and configure the connection appropriately. For auto-MDI/MDI-X to
operate correctly, the data rate on the interface and duplex setting must be set to Auto.
Available for copper ports only.
Duplex Sets the data flow mode for the link, and should generally match that of the attached device. Auto can be
used to auto-negotiate the duplex mode but may introduce a small delay during failover. See the
“Configuring port failsafe and LFP (TAP mode)” section on page 40 for instructions.
Available for copper ports only.
Mastery Sets the ports master/slave relationship with the link partner on a 1G RJ/copper link when in TAP mode.
In effect, it determines which end of the link is responsible for the synchronization clock. The link will
only work if there is one master and one slave.
The following master/slave settings are available:
Master! – Force Master
Slave! – Force Slave
Master? – Prefer Master
Slave? – Prefer Slave
For example, in TAP mode on port
AB, you should force the partner of A to have the same settings as B,
and vice versa, which (in the case of Mastery) is done be setting
A to Master! and B to Slave! (or the
opposite).
In non-TAP mode on port AB, you should set ports to either Master? or Slave?, but not to force. It
doesn’t matter which role is preferred.
Available for copper ports only.
TAP Enables failsafe and LFP (Link Failure Propagation) mode on the TAP pair (AB/CD). TAP pairs will
continue to pass traffic if there is a power or application failure. If one of the devices connected to the live
port fails, the other live port will immediately drop. Once the failed connected device is back on-line, the
other live port will immediately come back on-line. See the “Configuring port failsafe and LFP (TAP
mode)” section on page 40 for instructions.
Available for copper ports only.
Autolock A security feature that automatically triggers Lock if the link drops, which could indicate the cable has
been disconnected from the port or the link partner end. To unlock the port, remove the Lock selection.
This option is not enabled by default.
Lock A security feature that locks the port to prevent its usage. Lock can also be auto-triggered if Autolock is
enabled and a cable is removed. This option is not enabled by default.
