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 ip-selection {dest-ip | source-ip} mac {dest-mac | source-dest-mac | source-mac} tcp-udp enable 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. 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. 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) Defaults IP 4-tuple (IP SA, IP DA, Source Port, Destination Port) Command Modes CONFIGURATION Command History Version 7.6.1.0 Version 7.5.1.0 Added support for S-Series Introduced on C-Series 654 | IPv4 Routing
