Version Description
7.5.1.0 Introduced on the C-Series.
pre-6.1.1.0 Introduced on the E-Series.
load-balance
By default, for C-Series and S-Series, Dell EMC 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.
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. This option is enabled by default.
ingress-port
enable
Enter the keywords to distribute traffic based on the following:
● enable — Takes the source port into consideration when doing hash
computations. This option is disabled by default.
Defaults IP 4-tuple (IP SA, IP DA, Source Port, Destination Port)
