Hi Everybody,


I have a webserver which is very critical. So it connected to Cisco 2960 Switch. All the desktops are connected to this server and access web site.


But when the switch fails the webserver is unavailable. so i want introduce another 2960 switch and like to connect as per the diagram attached here.


Kindly educate me,


1. Whether this is the right method or best practice to achieve my requirement.


2. what configuration i have to do in switches?


Kindly guid me

Hello R.B. Kumar,


>> Do i have to do any configuration in Switches?


nothing special you can use spanning-tree portfast on the ports that need to be om the same Vlan


the server teaming must be of type active/standby only one NIC must speak at a given time


STP shouldn't play any role here the active NIC is the one used in both directions thanks to MAC address learning function


Hope to help

Giuseppe

Hello R.B. Kumar,


the server has to be configured for active/passive teaming


the two switch ports have to be on the same vlan


you cannot use both NICs at the same time with this setup
