Connectivity Guide
In this section, the term, "member link" refers to either a member physical port, in the case of port channels or next hop in the case of
ECMP groups.
With resilient hashing, when a member link goes down, the existing ows are not aected; they do not remap. Resilient hashing reassigns
the trac from the failed link to another member link without remapping the other existing ows. However, minimal re-mapping occurs
when a new member link is added.
Resilient hashing is supported both for Port Channels and Equal Cost MultiPath Groups (ECMP). Resilient hashing is a global conguration.
You can congure resilient hashing for both port channels and ECMP independently.
NOTE:
• Resilient hashing is supported only on certain platforms.
• The ow-map table always has an even number of entries.
To enable resilient hashing for Port Channels or ECMP groups, use the following commands in CONFIGURATION mode:
OS10(config)# enhanced-hashing resilient-hashing ecmp
OS10(config)# enhanced-hashing resilient-hashing lag
Supported platforms
The following table lists the platforms that support resilient hashing.
