load-balance (E-Series)
By default, for E-Series chassis, FTOS uses an IP 5-tuple to distribute IP traffic over members of a Port Channel as well
as equal cost paths. To designate another method to balance traffic over Port Channel members, use the
load-
balance
command.
E-Series
Syntax load-balance [ip-selection 3-tuple | ip-selection packet-based]
[mac]
To return to the default setting (IP 5-tuple), use one of the following commands:
•
no load-balance ip-selection 3-tuple
•
no load-balance ip-selection packet-based
•
no load-balance mac
Parameters
ip-selection 3-
tuple Enter the keywords
ip-selection 3-tuple
to distribute IP
traffic based on the following criteria:
• IP source address
• IP destination address
• IP Protocol type
NOTE: For IPV6, only the first 32 bits (LSB) of IP SA and IP DA are
used for hash generation.
ip-selection
packet-based Enter the keywords
ip-selection packet-based
to
distribute IPV4 traffic based on the IP Identification field in the IPV4
header. This option does not affect IPV6 traffic; that is, IPV6 traffic is
not distributed when this command is executed.
NOTE: Hash-based load-balancing on MPLS does not work when
packet-based hashing (
load-balance ip-selection
packet-based
) is enabled.
mac Enter the keyword
mac
to distribute traffic based on the following:
• MAC source address
• MAC destination address
Defaults IP 5-tuple (IP SA, IP DA, IP Protocol Type, Source Port and Destination Port)
