Add Fast ethernets Cisco 2801 ?

Hi,
I had bought a Router 2801. He has 2 Fast Ehternets, but I don't find any module for add more fast ethernets.
it's true?

Thanks!
 
You can add a HWIC-4ESW module that gives you a 4 port switch on the router.
 
You can have a HWIC-1FE or an HWIC-2FE to add more ethernet ports to the router. The HWIC-4esw with the addition of SVI's is a cheaper solution.
 
After extensive planning to use one of my hwic-4esw ints in my 2801 as a routed fast ethernet port I have now read that this is only a Layer 2 device.

Back to the drawing board.

Does anyone want to elaborate on using SVI's to work around my problem?

I have a lot more reading to do.... again.



 
I have a 2801 the two onboard FastEths and a HWIC-4esw card in it. I need two wans and one trunk to my switches. I had been planning on using the to Fasts for WANs and then one interface on the HWIC-4esw as the Lan trunk.

But I soon noticed that I couldn't put IP's on the HWIC interfaces, did a search and read this thread telling me what I feared... Since I don't have a HWIC-1FE, SVI's come into play.

Now I'm reading what is involved in using SVI's to make it work.. that's all.
 
Another work around is to do an 802.1q trunk to the FastE interfaces..

Well, if they do layer 2, why couldn't you trunk with one of the HWIC ethernet interfaces? You don't need an IP address to trunk...

With the 4ESW you can do this.

int Vlan 100
ip address 1.1.1.1 255.255.255.0
ip nat outside
int vlan 101
ip address 2.2.2.2 255.255.255.0
ip nat outside
etc, etc, etc...

To bind them to specific ports on the ESW do this

int fa 0/0/0
switchport access vlan 100
int fa 0/0/1
switchport access vlan 101


now you can use them as outside interfaces. The thing that sucks about this is not being able to use OER to control the routing. The reason this works is you are setting the ports to listen to traffic and assume that it belongs to the right vlan. It would be best to think of

int vlan 100
ip address 1.1.1.1 255.255.255.0
int fa 0/0/0
switchport access vlan 100

the same way you would think of

int fa 0/1
ip address 1.1.1.1 255.255.255.0

the difference is not that big when you are not trying to load balance the traffic.

Wow,

That was a great explanation, Wingatesl. So basically, if I made the 4esw port a trunk port I could listen to all the vlans like a FE port with sub-interfaces, no?

 
The reason I ask about making that 4esw port a trunk is because I have 12 vlans (vs the 4esw ints).

I originally was making 12 sub interfaces on the FE int until I decided to use it as one of my two wan ports.

Here's the capture from the router. (it still has the sub-ints because I'm not sure if I can use the 4esw for the task yet)
