simplifying a 1711 w/4port witch

[tony.schmitz]

I have a 1711-k9 router I am going to use for VPN.

I have configured Fastethernet0 (the WAN port) with no problem. Its just standard ethernet.

My problem is, that the LAN side is going through this WIC-4ESW switch.

I am sure it is a wonderful tool. But, I just need basic old fashioned LAN access. I understand that this is a higher level "layer3" type interface using VLANS.

But, I don't need it.

Obviously I am having difficulty getting it working.

I cannot seem to find any examples so far, as to how to set this up to just be a switch.

For some time I could not get any response on FASTETHERNET1 now I can get a response if I connect my laptop directly to the Fastethernet1.

But, I cannot get a response using the same laptop connected through a "dumb" switch/hub.

Can anyone direct me to some simplified examples of this used in a low security environment?

Any help would be appreciated.

This guide should help with the commands..

http://www.cisco.com/en/US/products/hw/routers/ps221/prod_configuration_basics09186a00801a055a.html

To assign all ports to a vlan

interface range fa 1-4 vlan X

X = vlan id.

To add VLan X to the database of the switch,

Router#vlan database

Router(vlan)#vlan X

To route packets via this vlan,

interface vlan X

ip address y.y.y.y

Now all ports of the 1711 will belong to Vlan X. Default gateway for PCs would be y.y.y.y

Hope that helps! Check the guide for more details.

I tried these commands on the 1711 with IOS 12.3

They would not work as shown.

I used the following:

interface range fa 1 - 4 vlan 2

This command failed; at the word "vlan".

Then I tried just;

interface range fa 1 -4

this brought me to;

config-if-range>

beneath this, the only things close were "vlan-id" and "vlan-range".

So, I could not get this to work.

What I have ended up doing is:

config> interface range fa 1 -4

config-if-range> switchport trunk native vlan 2

config-if-range> switchport mode trunk

This has allowed me access to all the ports on the switch as I would normally expect.

I would like to learn more about the Vlans and the differences between the switchport modes. So, I will read the link you supplied.

Thank you,

Why do you want the entire range of ports to be trunks?

From your description of what you're going to use those 4 FE's for, you would want to do the following:

conf-if-range> switchport mode access

conf-if-range> switchport access vlan 2

(or on the ports individually)

Unless you're going to be trunking other switches into those four ports, it is preferential to configure them as access ports.
