i have new to cisco 2960 -24TC-L switch and want to configue in CLI Mode .when i connect the lan to the switch users in the network disconnect from Internet.please help to configure it.
I suggest you connect to the switch via the serial console port and configure it before you connect it to your LAN. You can then either run through the basic setup script or drop straight to the CLI and configure in detail without affecting your users.
I have configured the switch mgmt VLAN an IP Address. Default GW ,name server ,ssh . Hope it will work now.
But I want to know the Difference of 2960TC-L and 2960PC-L .
