hello guys:
i ask a very simple question here:
how to distinguish a device is a router or a switch???

because in my study i can only see mark "2900 serila" on the devices, i can't see some mark like "cisco router" or "cisco switch" that can tell me clearly what this device is (a router or a switch)

how can i distinguish them(cisco devices)

i think maybe this is a very fool question but i really don't know about the way to distinguish them, wish not bother you too much!!

best wish!
