Link Aggregation

Link Aggregation Control Protocol (LACP) is part of the IEEE specification (802.3ad) that enables
you to bundle several physical ports together to form a single logical channel (LAG). LAGs multiply
the bandwidth, increase port flexibility, and provide link redundancy between two devices.
This switch supports two kinds of LAG.
• Static—A LAG is static if the LACP is disabled. The ports assigned to a static LAG are
always active members. After a LAG is manually created, the LACP option cannot be
added or removed until the LAG is edited and a member is removed (which can be added
prior to applying), then the LACP button becomes available for editing.
Dynamic—A LAG is dynamic if LACP is enabled. The ports assigned to dynamic LAG are
•
candidate ports. LACP determines which candidate ports are active member ports. The
non-active candidate ports are standby ports ready to replace any failing active member
ports.
Load Balancing
Traffic forwarded to a LAG is load-balanced across the active member ports, thus achieving an
effective bandwidth close to the aggregate bandwidth of all the active member ports of the LAG.
Traffic load balancing over the active member ports of a LAG is managed by a hash-based
distribution function that distributes Unicast and Multicast traffic based on Layer 2 or Layer 3
packet header information.
Back Pressure—Used with Half Duplex mode to slow down the packet
o
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
o
Auto Negotiation of flow control on the port (only when in Full Duplex
mode).
MDI/MDIX—Media Dependent Interface/Media Dependent
o
Interface with Crossover status on the port.
o
MDIX—Select to swap the port's transmit and receives pairs.
-
MDI—Select to connect this device to a station by using a
-
straight-through cable.
Auto—Select to configure this device to automatically detect
-
the correct pinouts for the connection to another device.
Description—Enter a port description.
