I have one cisco 2950 switch in which I have created 4 vlan for port 1,3,5,7 on 24th port I have given connection through firewall.
In 3 port I have connected one of my project routers.
Now the issue I am facing is no matter what setting I do on router and switch there is some speed mismatch that is taking place.
For eg I keep my router ethernet on speed auto, duplex auto and switch also on speed auto and duplex auto it works for sometime and then lose my connection and again if I change setting speed 100, duplex full on both the device I get connection for some time and then connection is lost, rest all the routers connected on switch are facing no issue, only this connection is facing the problem we have tried changing the port as well still the same issue.
My firewall port is seton speed 100 duplex auto.
Any help will be appreciated !! Thanks in advance.
