In addition, the
linecard
number
ip-sa-mask
value
ip-da-mask
value
option has the following
behavior to maintain bi-directionality:
•
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
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
Specify the maximum number of ECMP for a route. The range is 2 to 64.
path-fallback
Use the keywords
path-fallback
to enable this feature. If you enable the feature, re-
enter this keyword to disable the feature.
