Basically I've got to use netvis 4 to:

A.Ensure that all hosts can ping all other hosts.
B.Create 2 VLANs as follows: G and E in VLAN_1, and D and F in VLAN_2.
C.Create an Access List so that Host A is denied access to VLAN_2.

Firstly I need to get them all speaking. I've set the ip's of each host. The setup is as follows

Host A, B, C - connected to 1900switch

Then the switch goes to a 2600 router - which then goes to a 2950 switch

The 2950 switch connected to hosts D, E,

Then another switch which has F, G hosts connected. Basically I always presumed things would have an upling port - my understanding of this being that it connected to routers/switches together. I need to chain the 1900 to the 2600 which then connects to the 2950 - which then feeds to the other 2950.

Oh boy.. been a while since I did any setups from scratch, my support role tends to be fixing existing solutions rather than provisioning them, so my CCNA is more than a little rusty (looks like I left the CCNA book at my parents too! I've not used Netvis 4 much either

So all in all I'm in a perfect position to help you. Still lets see what I can do, though I'm not going to tell you everything, you should be learning this stuff

Cisco Catalyst 1900s? They're End Of Life these days, based on old 10BaseT stuff IIRC.. they do have an pair of 100BaseT uplinks though, and I think they support 802.1q.
There are uplink ports on the 2950s. Apart from adding ports in on the switches you'll need to setup VTP / 802.1q trunking on the uplink ports and then also on the router.
I'll do some digging around and see if I can find my old copy of Routersim.. without it I've only got my access to the online cisco academy docs to help.

Cheers mate

The 1900 has two ports on their own which I presume are the uplink ports. The 2600 has 2 groups of two ports:

F0/1 / F0/0 - Console and Aux

Everything to the right of the router can ping each other and the router fine - however the left side can't ven see the router (host a,b and c can see the switch but not the router - also the switch can't see the router.

Now, I had forgotten to set the ip/subnet of the 0/1 port of the router - but when I did it said the ip overlapped with port 0/0. Now, we have been "given" an ip range by our lecturer, mine being 192.168.13.x - noweverything on my network uses this. Is there a way to keep it and get 0/1 running - or do i have to change the range?

Update - I added an IP to the port 0/1 - so it's 192.168.14.1 rather than .13 - the switch on the left can ping anything on the right and the other switches can ping anything on the left - however...the hosts on the right can't ping anything on the left and vice-versa for the left side (apart from pinging things on their own side).

Edit again - everything pings now. I set the default gateway of the hosts to the router instead of the switch - so now .13 range can .14 range hosts (although I guess i can change them to .13 and point them to the .14 gateway)

Good luck

Just had a networking lab exam this morning....wasn't fun o.o

Robert and I spent about 5 hours last night trying to get the thing working. We got the VLANs up and everything talking to each other happily. However when we came to apply the access control list to block the traffic the routersim software decided to be a big pile of poo and not let us, for no obvious reason. I tried stuff on a real cisco 2600 at work but couldn't get it to work as I hadn't got the appropriate hardware. I grabbed a quick conversation with one of our Networks gurus (CCIE level guy), and confirmed what I thought was the case.

Routersim = teh sux0r.

Right command, right context, right syntax. It should apply, but because routersim is poo it won't.
