Configuring Cisco Express Forwarding
Restrictions
The Layer 4 load-balancing algorithm applies to software switched packets.
For platforms that switch traffic using a hardware forwarding engine, the hardware load-balancing
decision might be different from the software load-balancing decision for the same traffic stream. You
might want to override the configured algorithm.
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
ip cef load-sharing algorithm {universal [id]
include-ports {source [id] | [destination] [id]
| source [id] destination [id]}}
Example:
Router(config)# ip cef load-sharing algorithm
universal 111
Selects a Cisco Express Forwarding load-balancing
algorithm.
• The universal keyword sets the load-balancing
algorithm to one that uses a source and destination and
an ID hash.
• The include-ports source keyword sets the
load-balancing algorithm to one that uses the source
port.
• The id argument is a fixed identifier.
• The include-ports destination keyword sets the
load-balancing algorithm to one that uses the
destination port.
• The include-ports source destination keyword sets
the load-balancing algorithm to one that uses the source
and destination ports.
Step 4
end
Example:
Router(config)# end
Exits to privileged mode.
