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.
