ElastiCache Default Ports

Ensure AWS ElastiCache clusters are not using the default ports set for Redis and Memcached cache engines.

ElastiCache clusters should be configured not to use the default assigned port value for Redis (6379) and Memcached (11211).

Configure ElastiCache clusters to use the non-default ports.
