Ip Ecmp-Group - Dell S6100 Configuration Manual

•
In addition, the linecard number ip-sa-mask value ip-da-mask value option has the following
behavior to maintain bi-directionality:
•
•
•
•
The different hash algorithms are based on the number of Port Channel members and packet values. The default
hash algorithm (number 0) yields the most balanced results in various test scenarios, but if the default algorithm
does not provide a satisfactory distribution of traffic, use the hash-algorithm command to designate another
algorithm.
When a Port Channel member leaves or is added to the Port Channel, the hash algorithm is recalculated to balance
traffic across the members.

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 {number} command.
Parameters
maximum-paths
path-fallback
Defaults 16

When hashing is done on both IPSA and IPDA, the ip-sa-mask and ip-da-mask values must be equal.
(Single Linecard).
When hashing is done only on IPSA or IPDA, Dell Networking OS maintains bi-directionality with masks set to
XX 00 for stack-unit 1 and 00 XX for stack-unit 2 (ip-sa-mask and ip-da-mask). The mask value must be
the same for both stack-units when using multiple stack-units as ingress (where XX is any value from 00 to FF
for both stack-units). For example, assume that traffic is flowing between linecard 1 and linecard 2:
hash-algorithm linecard 1 ip-sa-mask aa ip-da-mask 00
hash-algorithm linecard 2 ip-sa-mask 00 ip-da-mask aa
Specify the maximum number of ECMP for a route. The range is 2 to 64.
Use the keywords path-fallback to enable this feature. If you enable the feature, re-
enter this keyword to disable the feature.
