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
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.
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 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. (By default, this is enabled.)
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. (By default, this is disabled.)
Defaults IP 4-tuple (IP SA, IP DA, Source Port, Destination Port)
