●
The second part comes from static physical configuration such as ingress and egress port numbers.
You can change the hash field to generate load balancing based on any parameters using the load-balance command.
ECMP commands
hash-algorithm
Changes the hash algorithm that distributes traffic flows across ECMP paths and the LAG.
Syntax
hash-algorithm {ecmp | lag} crc
Parameters
● ecmp — Enables ECMP hash configuration.
● lag — Enables LAG hash configuration for L2 only.
● crc — Enables CRC polynomial for hash computation.
Default
crc
Command Mode CONFIGURATION
Usage
Information
The hash value calculated with this command is unique to the entire system. Different hash algorithms
are based on the number of port-channel members and packet values. The default hash algorithm yields
the most balanced results in various test scenarios, but if the default algorithm does not provide a
satisfactory distribution of traffic, use this 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. The no version of this command returns the value to the default.
Example
OS10(config)# hash-algorithm lag crc
Supported
Releases
10.3.0E or later
link-bundle-utilization trigger-threshold
Configures a threshold value to trigger monitoring of traffic distribution on an ECMP link bundle.
Syntax
link-bundle-trigger-threshold value
Parameters value — Enter a link bundle trigger threshold value (0 to 100).
Defaults Not configured
Command Mode CONFIGURATION
Usage
Information
The no version of this command disables the configuration.
