ip vlan-flooding Enable unicast data traffic flooding on VLAN member ports. E-Series Syntax Defaults Command Modes Command History ip vlan-flooding To disable, use the no ip vlan-flooding command. Disabled. INTERFACE Version 8.1.1.0 Version 7.4.1.0 Introduced on the E-Series ExaScale. Introduced on the E-Series. 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, S-Series, Z-Series) 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. C-Series, S-Series, Z-Series, S4810 Syntax Parameters load-balance {ip-selection [dest-ip | source-ip]} | {mac [destmac | 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. ip-selection {dest-ip | sourceip} 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. • 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. 797
