Solution

This issue occurred due to an unsupported configuration in which the customer attempted to add more than 64 member interfaces to a single AE bundle. The platform does not support exceeding 64 member interfaces in the current software release.


If the customer requires support for more than 64 member interfaces, they should upgrade to a software release that includes RLI 62137, which increases the supported limit to 256 member links.
