Cisco Small Business 200, 300 and 500 Series Managed Switch Administration Guide (Internal Version)
• Administrative Duplex Mode—Select the port duplex mode. This field is
configurable only when auto-negotiation is disabled, and the port speed is
set to 10M or 100M. At port speed of 1G, the mode is always full duplex. The
possible options are:
- Full—The interface supports transmission between the device and the
client in both directions simultaneously.
- Half—The interface supports transmission between the device and the
client in only one direction at a time.
• Operational Duplex Mode—Displays the ports current duplex mode.
• Auto Advertisement—Select the capabilities advertised by auto-
negotiation when it is enabled. The options are:
- Max Capability—All port speeds and duplex mode settings can be
accepted.
- 10 Half—10 Mbps speed and Half Duplex mode.
- 10 Full—10 Mbps speed and Full Duplex mode.
- 100 Half—100 Mbps speed and Half Duplex mode.
- 100 Full—100 Mbps speed and Full Duplex mode.
- 1000 Full—1000 Mbps speed and Full Duplex mode.
• Operational Advertisement—Displays the capabilities currently published
to the ports 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 device 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.
