How to know if a existing AWS ELB is either Classic or Application load Balancer

Question

I got responsible for the management of a AWS account with a preexisting load balancer, and want to know if it is a Classic load balancer or an application load balancer.

I could not find the information either through the web console or the ruby API

Answer 1

In the web console when you look at your list of load balancers there is a "Type" column that tells you which type it is.

Answer 2

With API V2 describe-load-balancers command will give you the type of the ELB.

aws elbv2 describe-load-balancers --names my-load-balancer

Type will indicate the type of the ELB
