Load-Balancing Configuration For LAG and ECMP:
----------------------------------------------
IPV4 Load Balancing : Enabled
IPV6 Load Balancing : Enabled
MAC Load Balancing : Enabled
TCP-UDP Load Balancing : Enabled
Ingress Port Load Balancing : Disabled
IPV4 FIELDS : source-ip destination-ip protocol vlan-id l4-destination-port l4-source-port
IPV6 FIELDS : source-ip destination-ip protocol vlan-id l4-destination-port l4-source-port
MAC FIELDS : source-mac destination-mac ethertype vlan-id
TCP-UDP FIELDS: l4-destination-port l4-source-port
• The second part generates from the static physical conguration such as the ingress and egress port numbers.
To generate load balancing based on any parameters, change the hash eld using the load-balance command.
ECMP commands
hash-algorithm
Changes the hash algorithm that distributes trac ows across ECMP paths and the link aggregation group (LAG).
Syntax
hash-algorithm {ecmp | lag} crc
Parameters
• ecmp — Enables the ECMP hash conguration.
• lag — Enables the LAG hash conguration for Layer 2 (L2) only.
• crc — Enables the cyclic redundancy check (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. Dierent 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 trac,
use this command to designate another algorithm.
When a port-channel member leaves or is added to the port-channel, the hash algorithm recalculates to balance
trac across the members. The no version of this command returns the value to the default.
Example
OS10(config)# hash-algorithm lag crc
