Version 9.0(1.3) Introduced on the S5000.
load balance
By default, for the S5000, 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.
S5000
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.
