Usage Information
By default, FTOS distributes incoming traffic based on a hash algorithm using the following criteria:
• IP source address
• IP destination address
• TCP/UDP source port
• TCP/UDP destination port

Commands
load-balance hg
z
Choose the traffic flow parameters to be used in the hash calculation while distributing the traffic
across internal higig links.
Syntax
[no] load-balance hg { ip-selection | ipv6-selection [source-ip | source-ipv6 | source-port-id |
source-module-id | dest-ip | dest-ipv6 | dest-port-id | dest-module-id | protocol | vlan |
L4-source-port | L4-dest-port ] | mac [source-mac | source-port-id | source-module-id | dest-mac |
dest-port-id | dest-module-id | vlan | ethertype | source-dest-mac] | tunnel [ipv4-over-ipv4 |
ipv4-over-gre-ipv4 | mac-in-mac]}
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 which port the
packet should be forwarded to.
• source-ip—Uses source IP address and source port fields to hash. The
hashing mechanism returns a 3-bit index indicating which port the
packet should be forwarded to.
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 which port the packet should
be forwarded to.
• 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 which port the
packet should be forwarded to.
• 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 which port the packet should be
forwarded to.
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)
