i am a little confused about the concept of default-gateway and management ip's / VLAN's in L2 and L3 switches.
i can understand the importance of a DGW on a switch when a switch is sending traffic to its GW, but whats its role while we are accessing / telnetting into a switch.A switch doesnt allow access if its DGW is not correctly set.
What is the purpose of Management IP's / VLAN on a switch??
What do cisco means when it says that following switch is transparent ?
Default-gateway is generally added on L2 switches which are not capable of doing routing. This is a way of telling them to fwd the traffic for all non-connected hosts to the DG.
Management IP's are used to manage a device i.e. you could telnet to a device from remote when you have assigned switch an IP. otherwise you need to connect thru console everytime & need to be near the device to be able to configure it.
So, DG is something to do with traffic & Managmnt IP is something to do with management.
A L3 switch do has some IP on its physical or logical interface, through which we can telnet it.But the main purpose of using mgnt IP is that if some time the interface goes down we can access the switch via mgt IP....Am i right ??
