Cisco Small Business SLM Series Smart Switches Administration Guide
•
Neighbor Advertisement — The neighbor port (the port to which the
selected interface is connected) advertises its capabilities to the port to
start the negotiation process.
•
Back Pressure — Enables Back Pressure mode on the port. Back Pressure
mode is used with Half Duplex mode to allow ports to prevent the link
partner from sending traffic. The Back Pressure mode is configured for
ports currently in the Half Duplex mode.
•
Current Back Pressure — Displays the Back Pressure mode on the port.
•
Flow Control — Enables or disables flow control or enables the auto
negotiation of flow control on the port.
•
Current Flow Control — Displays the current Flow Control setting.
•
MDI / MDIX — Defines the Media Dependent Interface (MDI) / Media
Dependent Interface with Crossover (MDIX) mode 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 connected 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:
-
MDIX
— Use for hubs and switches.
-
Auto
— Use to automatically detect the cable type.
-
MDI
— Use for end stations.
•
Current MDI / MDIX — Displays the current MDI / MDIX setting.
•
LAG — Indicates the LAG number of which this port is a member, if relevant.
Define the relevant fields.
Click Save Settings. The settings are modified, and the device is updated.
Link Aggregated Groups optimize port usage by linking a group of ports together
to form a single aggregated group. Link aggregated groups multiply the
bandwidth between the devices, increase port flexibility, and provide link
redundancy.
