Configuring Ports
Page 72
–
Full — The interface supports transmission between the device and its link partner in both directions
simultaneously.
–
Half — The interface supports transmission between the device and the client in only one direction at a
time.
•
Auto Negotiation — Displays the auto negotiation status on the port. Auto negotiation is a protocol between
two link partners that enables a port to advertise its transmission rate, duplex mode, and flow control abilities
to its partner.
•
Advertisement — Defines the auto negotiation setting the port advertises. The possible field values are:
–
Max Capability — Indicates that all port speeds and duplex mode settings are accepted.
–
10 Half — Indicates that the port advertises for a 10 Mbps speed port and half duplex mode setting.
–
10 Full — Indicates that the port advertises for a 10 Mbps speed port and full duplex mode setting.
–
100 Half — Indicates that the port advertises for a 100 Mbps speed port and half duplex mode setting.
–
100 Full — Indicates that the port advertises for a 100 Mbps speed port and full duplex mode setting.
–
1000 Full — Indicates that the port advertises for a 1000 Mbps speed port and full duplex mode setting.
–
1000 Half — Indicates that the port advertises for a 1000 Mbps speed port and half duplex mode setting.
•
Back Pressure — Displays the back pressure mode on the Port. Back pressure mode is used with half
duplex mode to disable ports from receiving messages.
•
Flow Control — Displays the flow control status on the port. Operates when the port is in full duplex mode.
•
MDI/MDIX — Displays the MDI/MDIX status on the port. Hubs and switches are deliberately wired opposite
the way end stations are wired, so that when a hub or switch is connected to an end station, a straight through
Ethernet cable can be used, and the pairs are matched up properly. When two hubs or switches are con-
nected to each other, or two end stations are connected to each other, a crossover cable is used to ensure
that the correct pairs are connected. The possible field values are:
–
Auto — Use to automatically detect the cable type.
–
MDI (Media Dependent Interface) — Use for end stations.
–
MDIX (Media Dependent Interface with Crossover) — Use for hubs and switches.
•
LAG — Indicates whether the port is part of a Link Aggregation Group (LAG).
•
PVE — Enables a port to be a Private VLAN Edge (PVE) port. When a port is defined as PVE, it bypasses the
Forwarding Database (FDB), and forwards all Unicast, Multicast and Broadcast traffic to an uplink (except
MAC-to-me packets). Uplinks can be a port or LAG. Traffic from the uplink is distributed to all interfaces.
The Interface Configuration LAG table contains the following fields:
•
LAG — Indicates whether the port is part of a Link Aggregation Group (LAG).
•
Description — Provides a user-defined port description.
•
LAG Type — Indicates the type of LAG defined by the first port assigned to the LAG. For example, 100-Cop-
per, or 100-Fiber.
•
LAG Status — Indicates whether the LAG is up or down.
•
LAG Speed — Displays the configured aggregated rate for the LAG. The possible field values are:
–
10 — Indicates the port is currently operating at 10 Mbps.
–
100 — Indicates the port is currently operating at 100 Mbps.
–
1000 — Indicates the port is currently operating at 1000 Mbps.
•
Auto Negotiation — Displays the auto negotiation status of the LAG. Auto negotiation is a protocol between
two link partners that enables a port to advertise its transmission rate, duplex mode, and flow control abilities
to its partner.
•
Flow Control — Displays the flow control status of the LAG.
