How is it possible to Authenticate switch B on Switch A (LAN) for e.g Location A switch is connected with 25 clients (via sub switch) and Location B switch has 40 clients.

Port#8 on switch A is connected to Port#6 on Switch B via Cat6 cable. Both are on same subnet and LAN.

So 25 clients on Location A are able to communicate other 40 clients at Location B (vice versa)

I want to authenticate connection between these two switches. Means if Port#8 on switch A will always check if other side switch is whitelisted or not.

If otherside switch is not whitelisted then traffic between these two switches must stop.

I think MAC lock is not possible because there is no routing or layer 3 connections.

Only want to authentic ports.

Pls help me to accomplish this.

Thanx

Not sure what you are asking. If you are looking for some form of dynamic filter sorta like a hotel uses where you must log in and then traffic is allowed, that you would need a firewall to accomplish. A switch in general does not have that feature.

A switch is a pretty stupid device. It is designed to pass traffic without delays. Because of this many fancy feature are not included because it would slow traffic down.

Now many managed switches allow you to put in mac filters on the ports. This is a manual list you must configure so it is not automatic. Security on a switch is generally done with 802.1x. This would be done on the remote switch...ie switch B.
