NOTE: While the seed is stored separately on each port-pipe, the same seed is
used across all CAMs.
You cannot separate LAG and ECMP but you can use different algorithms
across the chassis with the same seed. If LAG member ports span multiple
port-pipes and line cards, set the seed to the same value on each port-pipe to
achieve deterministic behavior.
If the hash algorithm configuration is removed, the hash seed does not go to
the original factory default setting.
ip ecmp-group
Enable and specify the maximum number of ecmp that the L3 CAM hold for a route, By default, when
maximum paths are not configured, the CAM can hold a maximum of 16 ecmp per route.
Syntax
ip ecmp-group {maximum-paths | {
number
} {path-fallback}
To negate a command, use the
no ip ecmp-group maximum-paths
command.
Parameters
maximum-
paths
Specify the maximum number of ECMP for a route. The
range is 2 to 64.
path-fallback
Use the keywords

to enable this feature. If
you enable the feature, re-enter this keyword to disable the
feature.
