l4-load-balancing
Syntax
[no] l4-load-balancing
Context
config>system
Description
This command configures system-wide Layer 4 load balancing. The configuration at system level can
enable or disable load balancing based on Layer 4 fields. If enabled, Layer 4 source and destination
port fields will be included in hashing calculation for TCP/UDP packets.
The hashing algorithm addresses finer spraying granularity where many hosts are connected to the
network.
To address more efficient traffic distribution between network links (forming a LAG group), a
hashing algorithm extension takes into account L4 information (i.e., src/dst L4-protocol port).
The hashing index can be calculated according to the following algorithm:
This algorithm will be applied to all packets received on network and access ports (Layer 2 and Layer
3) with two exceptions
Use of Layer 4 information (TCP/UDP ports) will not be used in following cases:

Description
This command configures the Link Aggregation Control Protocol (LACP) system priority on
aggregated Ethernet interfaces. LACP allows the operator to aggregate multiple physical interfaces to
form one logical interface.

• MPLS LSR switched packets will be load balanced using a hash of the label stack, incoming
port, and system IP address.
• Packets of point-to-point services (Epipe) will be hashed based on the service ID.
• Fragmented packets.
• Packets received from a VPRN tunnel.
