load-balance
By default, for C-Series and S-Series, Dell Networking OS 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 load-balance {ip-
selection [dest-ip | source-ip]} | {mac [dest-mac | source-dest-
mac | source-mac]} | {tcp-udp | ingress-port [enable]}command.
Parameters
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.
• 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.
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.
• 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.
• 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.
