hi i have a cisco 837 router and i can access the sdm as usual.

note: i do not have an (adsl line) as im currently with virgin using their vmdg480 router that i have currently changed from default dhcp & set to (modem/enable) instead that provides me with public address details at my isa 2006/external nic.

note:  currently i have set my win 2003 server as 192.168.0.2/24 that enables me to ping the below address which also allows me access to the sdm gui:

config t
int eth0
ip address 192.168.0.1 255.255.255.0
no shut

config t
int fa1
description connected to win 2003 server as stated above
no ip address

config t
int fa2
ip address x.x.x.x x.x.x.x
ip addresses may not be configured on l2 links
no switchport
%invalid input detected at '^' marker

config t
description x-over cable connected to virgin vmdg480 router to internet
int fa4
no ip address

question 1.  can anyone tell me what i need to configure next in order for me to enable the lan ports fa1 & 4 as only offers: gre or loopback  ?

You can't put ip addresses directly on the FA ports, they are layer 2 only. Instead you need to create VLAN interfaces which do support layer 3 ip addresses.

For example:

inter vlan 2
ip add x.x.x.x y.y.y.y

inter fa2
switchport access vlan 2

hi

i have not managed to return back to my cisco 837 wan connectivity issue as yet but sometime next week i will do!!

question 1.  just for clarification, are you saying adding a 'vlan' on a port will change it from layer 2 to layer 3 and make it a 'wan' connection  ?

i will even add 'ip routing' which i am not sure is needed as assumed it was when 'routing protocols' were used

by the way the following does not work at all on ciso 837:

config t
int vlan 2 - invalid input

Hello again.

I did some research on the 830 series, because to be honest I haven't worked with one in years.
I'm afraid you are out of luck. The built-in switch doesn't support VLANs. It simply acts a dumb switch, using Ethernet0 for layer3 access. That means you can only configure a single internal network, apart from loopback interfaces.  This Q&A lists the differences between models, and you need a 850 or 870 series in order to get VLAN support in the switch.

In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
Quality of Service (QoS) options are nearly endless when it comes to networks today. This article is merely one example of how it can be handled in a hub-n-spoke design using a 3-tier configuration.
