Packet Tracer - can't assign IP address to switch fastethernet 0/1

SurferdudeHB

can someone tell me what I'm doing wrong here. Why can't assign the IP address to interface fastethernet 0/1

THis is for a 2950-24 switch in Packet Tracer

switch01(config)#interface vlan 1
switch01(config-if)#ip address 192.168.1.5 255.255.255.0
switch01(config-if)#no shutdown

switch01(config-if)#
%LINK-5-CHANGED: Interface Vlan1, changed state to up
switch01(config-if)#interface fast 0/1
switch01(config-if)#ip address 192.168.1.1 255.255.255.0

You cant' assign an IP address to a Layer 2 switchport.. Maybe you're thinking router?

You can do it if it's a chassis switch (4006, 6509) by typing in no switchport, but you won't find that in packet tracer. Routers and L2 switches serve two completely different purposes

Duh! ok thx guys

Think:

Switch = Layer 2 = MAC Address
Router = Layer 3 = IP Address


However a switch can be assigned an administrative IP Address via a vlan interface.

Correct. This is primarily for remote management. One of the biggest things between a L2 and L3 switch is that on L2 switches, you have to configure subinterfaces on an attached router for intervlan routing. On a L3 switch, you can use SVIs to define the address pool for each VLAN (After enabling IP routing) so then you don't even need a router to route them between vlans.
