load-balance

By default, 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:

NOTE: The hashing mechanism returns a 3-bit index indicating which port the packet should be forwarded.

dest-ip — Uses destination IP address and destination port fields to hash.

source-ip — Uses source IP address and source port fields to hash.

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.

source-dest-mac — Uses the destination and source MAC address, VLAN, Ethertype, source module ID and source port ID fields to hash.

source-mac — Uses the source MAC address, VLAN, Ethertype, source module ID and source port ID fields to hash.

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)
