• Operational Advertisement—Displays the capabilities currently published
to the port's neighbor. The possible options are those specified in the
Administrative Advertisement field.
• Neighbor Advertisement—Displays the capabilities advertised by the
neighboring device (link partner).
• Back Pressure—Select the Back Pressure mode on the port (used with Half
Duplex mode) to slow down the packet reception speed when the switch is
congested. It disables the remote port, preventing it from sending packets
by jamming the signal.
• Flow Control—Enable or disable 802.3x Flow Control, or enable the auto-
negotiation of Flow Control on the port (only when in Full Duplex mode).
• MDI/MDIX—the Media Dependent Interface (MDI)/Media Dependent
Interface with Crossover (MDIX) status on the port.
The options are:
- MDIX—Select to swap the port's transmit and receives pairs.
- MDI—Select to connect this switch to a station by using a straight
through cable.
- Auto—Select to configure this switch to automatically detect the correct
pinouts for the connection to another device.
• Operational MDI/MDIX—Displays the current MDI/MDIX setting.
• Protected Port—Select to make this a protected port. (A protected port is
also referred as a Private VLAN Edge (PVE).) The features of a protected port
are as follows:
- Protected Ports provide Layer 2 isolation between interfaces (Ethernet
ports and LAGs) that share the same VLAN.
- Packets received from protected ports can be forwarded only to
unprotected egress ports. Protected port filtering rules are also applied
to packets that are forwarded by software, such as snooping
applications.
