Connecting 2 Cisco Switches
Posted on 2007-11-14
Currently I have 1 Cisco Catalyst 3750G switch, Switch_A. Switch_A has VLAN 20 and VLAN 30 configured, and each VLAN has servers and workstations connected to it. Now I wish to connect a Cisco Catalyst 2960G switch, Switch_B to Switch_A. Switch_B will have only VLAN 30. Devices connected to Switch_B need to communicate with devices in VLAN 20 and VLAN 30. In this case, do I have to configure the ports that interconnect the switches? (e.g. trunk?) Or I only need to connect Switch_B to any port of VLAN 30 in Switch_A via a crossover cable? Please help. Thank you.
