IPv4 Routing | 675
c s
By default for C-Series and S-Series, FTOS uses an IP 4-tuple (IP SA, IP DA, Source Port,
and Destination Port) 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.
Syntax
load-balance {ip-selection [dest-ip | source-ip]} | {mac [dest-mac | source-dest-mac |
source-mac
]} | {tcp-udp | ingress-port [enable]}
To return to the default setting (IP 4-tuple), use the
no version of the command.
Parameters
Defaults
IP 4-tuple (IP SA, IP DA, Source Port, Destination Port)

ip-selection {dest-ip |
source-ip
}
Enter the keywords to distribute IP traffic based on the following
criteria:
• dest-ip — Uses destination IP address and destination port fields
to hash. The hashing mechanism returns a 3-bit index indicating
to which port the packet should be forwarded.
• source-ip — Uses source IP address and source port fields to
hash. The hashing mechanism returns a 3-bit index indicating to
which port the packet should be forwarded.
mac {dest-mac |
source-dest-mac |
source-mac
}
Enter the keywords to distribute MAC traffic based on the following
criteria:
• dest-mac — Uses the destination MAC address, VLAN,
Ethertype, source module ID and source port ID fields to hash.
The hashing mechanism returns a 3-bit index indicating to which
port the packet should be forwarded.
• source-dest-mac — Uses the destination and source MAC
address, VLAN, Ethertype, source module ID and source port ID
fields to hash. The hashing mechanism returns a 3-bit index
indicating to which port the packet should be forwarded.
• source-mac — Uses the source MAC address, VLAN,
Ethertype, source module ID and source port ID fields to hash.
The hashing mechanism returns a 3-bit index indicating to which
port the packet should be forwarded.
tcp-udp enable
Enter the keywords to distribute traffic based on the following:
• enable — Takes the TCP/UDP source and destination ports into
consideration when doing hash computations. (By default, this is
enabled)
ingress-port enable
Enter the keywords to distribute traffic based on the following:
enable — Takes the source port into consideration when doing hash
computations. (By default, this is disabled.)
