Usage Information
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 unicast-host-route
command.
Example
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
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 [dest-ip |
source-ip]} | {mac [dest-mac | source-dest-mac | source-mac]} | {tcp-udp |
ingress-port [enable]}command.
Parameters
ip-selection {dest-
ip | source-ip}
Enter the keywords to distribute IP traffic based on the following criteria:
