Equal Cost Multi-Path
Overview
The characters that appear below command headings indicate support for the associated Dell Force10
platform, as follows:
• C-Series: c
• E-Series: e
• S-Series: s
Commands
The ECMP commands are:
• hash-algorithm
• hash-algorithm ecmp
• hash-algorithm seed
• ip ecmp-deterministic
• ipv6 ecmp-deterministic
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 the 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.
