Packet Tracer - How to assign a VLAN to 2800 router port

[marianodaniel]

Hello! I'm doing some tasks on PT. I found one where I have a 2800 Router and I'm trying to assign a VLAN to Fa0/1 but cannot seem to find the command to do so.

Hello,

interface Fa0/1 is a layer 3 interface (as evidenced by the 'no ip address' configuration under that interface. You can only assign Vlans to layer 2 interfaces (or to subinterfaces, as you already did in your example)...

Hello @marianodaniel 

Cisco 2811 router have got L3 interfaces. You can assign IP addresses but no vlan as you want to do.

As like a VLAN access port?

If so, may not be possible on a 2800 native routed port.

Of course, routed ports often support subinterfaces, which allows a router to work with a switch trunk port.

ISRs might also support bridge ports, allowing a BVI (believe later IOSs changed terminology).

Again, not sure you can mix a SVI with a routed port.

Possible option, use an Ethernet module.

@marianodaniel hi, fa 0/0 and fa0/0 are routed ports. you cannot convert them to switch ports. but if you add module like HWIC-4ESW, you can configure VLAN on those new ports.
