-
Half—The interface supports transmission between the switch and the
client in only one direction at a time.
•
Operational Advertisement—Displays the capabilities currently published
to the port's neighbor to start the negotiation process. The possible options
are those specified in the Auto Advertisement Speed and Duplex fields.
•
Back Pressure—Check Enable to enable 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).
•
Current Flow Control—Displays the current status of 802.3X flow control.
•
Protected Port—Check Enable 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 Link Aggregation Groups (LAGs)) that share the same
Broadcast domain (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.
-
Port protection is not subject to VLAN membership. Devices connected
to protected ports are not allowed to communicate with each other, even
if they are members of the same VLAN.
-
Both ports and LAGs can be defined as protected or unprotected.
•
Member in LAG—If the port is a member of a LAG, the LAG number
appears; otherwise this field is left blank.
Click Apply. The port settings are modified, and the Running Configuration is
updated.
