docker swarm throws 404 page not found error while checking node details

I'm setting up a swarm cluster. I am able to see the details with docker -H :4000 info. However when i try docker -H :4000 node ls it fails.

OS - RHEL 7

docker version:

$ docker version
Client:  
 Version:      1.12.3  
 API version:  1.24  
 Go version:   go1.6.3  
 Git commit:   6b644ec  
 Built:  
 OS/Arch:      linux/amd64  

Server:  
 Version:      1.12.3  
 API version:  1.24  
 Go version:   go1.6.3  
 Git commit:   6b644ec  
 Built:  
 OS/Arch:      linux/amd64

docker info:

$ docker -H :4000 info
Containers: 23

docker node ls:

docker -H :4000 node ls
*Error response from daemon: 404 page not found*

http-proxy.conf:

[Service]
[Service] Environment="HTTP_PROXY=http://proxy-domain.com:port" "HTTPS_PROXY=https://proxy-domain.com:port"

docker.conf:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock -g /docker --cluster-store=consul://0.0.0.0:8500 --cluster-advertise eth0:2375

Not sure what I am missing here. My goal here is to apply swarm node label metadata so that I can make different pools as their sizes. Any help would be appreciated.

PS: I am able run docker -H 4000 pull/start/stop/rmi/rm/network commands without any issue. its the "node" command does not work with swarm cluster.

Thanks in Advance

I am currently using docker swarm with service discovery(consul). docker swarm node management is available on new docker swarm mode(natively supported by docker engine 1.12+ - https://docs.docker.com/engine/swarm/). I will update the infrastructure to new swarm mode and will provide my findings here.
