Command Modes CONFIGURATION Command History Version 9.9(0.0) 9.5(0.1) 9.3(0.1) Description Introduced on the C9010. Introduced on the Z9500. Introduced on the S6000. Usage Information Example Route prefixes stored in the L3 host table are managed using ECMP next-hop forwarding. A warning message is displayed after you enter the command stating that this setting takes effect for existing routes only when IPv4 route prefixes are cleared from the LPM routing table (RTM). To enable storage of IPv4 route prefixes in the LPM table, disable this setting by entering the no ipv4 unicasthost-route command. Dell(conf)#ipv4 unicast-host-route Warning: Command will take effect for existing routes only when IPv4 route prefixes are cleared from RTM Dell(conf)#no ipv4 unicast-host-route load-balance By default, the system 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. C9000 Series Syntax Parameters 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 [destip | source-ip]} | {mac [dest-mac | source-dest-mac | source-mac]} | {tcpudp | ingress-port [enable]}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. ● 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. 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. ● 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. ● 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. tcp-udp enable Enter the keywords to distribute traffic based on the following: 928 IPv4 Routing
