Usage
Information
Using the Configuration command mode, create an ECMP group ID. Interfaces can
then be assigned to the ECMP group using the CONFIGURATION ECMP-GROUP
command mode. Link bundle monitoring can be enabled on the port-channel
configuration using the CONFIGURATION ECMP-GROUP command mode.
hash-algorithm
e
Change the hash algorithm used to distribute traffic flows across a Port Channel. The
ECMP, LAG, and line card options are supported only on the E-Series TeraScale and
ExaScale chassis.
Syntax
hash-algorithm
{algorithm-number | {ecmp {checksum | crc | xor} [number] lag
{checksum | crc | xor} [number] nh-ecmp {checksum | crc | xor}[number] linecard
number ip-sa-mask value ip-da-mask value}
To return to the default hash algorithm, use the
no hash-algorithm command.
To return to the default Equal-cost Multipath Routing (ECMP) hash algorithm, use
the
no hash-algorithm ecmp algorithm-value command.
To remove the hash algorithm on a particular line card, use the
no hash-algorithm
linecard
number command.
