Command
History
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.
Parameters
Defaults IP 4-tuple (IP SA, IP DA, Source Port, Destination Port)

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.
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 to.
• 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 to.
• 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 to.
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. (By default, this is
enabled )
Version 7.6.1.0 Added support for S-Series
Version 7.5.1.0 Introduced on C-Series
