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 trac over members of a Port Channel as well as equal-cost paths. To designate another method to balance trac 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 trac based on the following criteria:
• dest-ip — Uses destination IP address and destination port elds 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 elds 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 trac based on the following criteria:
• dest-mac — Uses the destination MAC address, VLAN, Ethertype, source module
ID and source port ID elds 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 elds 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 elds 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 trac 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 trac 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)
