on switch 3550, we can create vlans and SVI and use the IP routing command to enable the vlans to talk to each other without connecting the switch to the router.
What I need to understand is :
1- when connecting the 3550 switch to another L3 or L2 switch, would the connecting ports be configured as Trunk ports
2-when the 3550 swithc is connected to a Router, would the switch connecting port be configured as trunk port or we need to use No Switchport command. ?
what is the difference?
