Understanding Ethernet Link Aggregation on ACX Series Routers

Ethernet link aggregation is mechanism for increasing the bandwidth linearly and

improving the resiliency of Ethernet links by bundling or combining multiple full-duplex

same-speed point-to-point Ethernet links into a single virtual link. The virtual link interface

is referred to as link aggregation group (LAG) or aggregated Ethernet (AE) interface. The

LAG balances traffic across the member links within an aggregated Ethernet bundle and

effectively increases the uplink bandwidth. Another advantage of link aggregation is

increased availability, because the LAG is composed of multiple member links. If one

member link fails, the LAG continues to carry traffic over the remaining links.

NOTE: ACX Series routers support connectivity fault management (CFM)

on aggregated Ethernet interfaces with continuity check interval of 100

milliseconds or higher.

NOTE: ACX5048 and ACX5096 routers support connectivity fault

management (CFM) on aggregated Ethernet interfaces with continuity check

interval of 1 second or higher.

NOTE: The Ethernet options configurations for ACX5048 and ACX5096

routers differ compared to other ACX Series routers. For more information,

see “Understanding Layer 2 Next GenerationMode on ACX5048 and ACX5096

Routers” on page 1167.

On ACX Series routers, up to 128 AE interfaces can be created with each AE interface

having up to 8 physical interfaces. AE interfaces can be created across PICs and

fixed-ports on the chassis.

NOTE: On ACX5048 and ACX5096 routers, up to 64 AE interfaces can be

created with each AE interface having up to 16 physical interfaces.

ACX Series routers do not support statistics for aggregated Ethernet interface. However,

statistics can be retrieved for member interface.
