•
Administrative Duplex Mode—If Auto Negotiation is disabled, select Half
for half-duplex or Full for full-duplex operation.
•
Admin Advertisement—If Autonegotiation is enabled, select the highest
port speed and duplex setting that you want the port to negotiate. If you
select Max Capacity, the port autonegotiates up to the highest port speed
and duplex setting supported by hardware.
•
Flow Control—Select to enable IEEE 802.3x flow control. Flow control helps
to prevent data loss when the port cannot keep up with the amount of frames
being switched. When enabled, the switch can send a PAUSE frame to stop
traffic on a port if the amount of memory used by packets on the port
exceeds a preconfigured threshold. The paused port does not forward
packets for the period of time specified in the PAUSE frame. When the
PAUSE frame time elapses or the utilization returns to a specified low
threshold, the switch enables the port to again transmit frames.
•
Member in LAG—Indicates whether the port is a member of a Link
Aggregation Group. See
LAGs.
•
MTU—Specify the maximum transmission unit size in bytes. The default
MTU is 1518 and the range is between 1518 and 9216 bytes.
Click Apply and then click Close. Your changes are saved to the Running
Configuration.
Link Aggregation allows one or more full-duplex Ethernet links to be aggregated
together to form a Link Aggregation Group (LAG). The switch treats the LAG as if it
is a single physical port, with improved fault tolerance and load- sharing capability.
A LAG interface can be either static or dynamic:
•
Static LAG—Ports are assigned to a LAG directly by the administrator. The
ports remain dedicated LAG members until configured otherwise.
