Usage
Information
By default this command is disabled. When enabled, all the Layer 3 unicast routed data traffic going
through a VLAN member port is flooded across all the member ports of that VLAN. There might be
some ARP table entries which are resolved through ARP packets which had Ethernet MAC SA
different from MAC information inside the ARP packet. This unicast data traffic flooding occurs only
for those packets which use these ARP entries.
load-balance (C-Series and S-Series)
c s
By default for C-Series and S-Series, FTOS 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 [enable]}
To return to the default setting (IP 4-tuple), use the no version of the command.

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 to.
• 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 to.
