Hi Gurus,

 

Below are the three VLAN's I have created on my First Switch for the first time ion my lift after watching couple of videos.I am connected to the switch using a serial to usb cable via console.

 

sw1#show vlan

OS Version and type of Switch(L2)

 

sw1#show version
Cisco Internetwork Operating System Software
IOS (tm) C2950 Software (C2950-I6K2L2Q4-M), Version 12.1(22)EA14, RELEASE SOFTWARE (fc1)

 

IP address assigned;;

 

interface Vlan1
 no ip address
 no ip route-cache
 shutdown

interface Vlan101
 ip address 10.0.1.1 255.255.255.0

 no ip route-cache

 no ip route-cache
 shutdown
!
interface Vlan103
 ip address 15.0.10.10 255.255.255.0

 no ip route-cache
 shutdown

 

IP address on my computer;

Wireless LAN adapter Wireless Network Connection:

   Connection-specific DNS Suffix  . : Home
   Pv4 Address. . . . . . . . . . . : 192.168.0.12
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.0.1

 

Now I cannot ping any of the IP's assigned to the VLAN's. What to do with the VLAN's I've created [stupid and dumb question]. I want to play around the switch and connect it to a Cisco router(I have 5 routers and 5 switches, all different) and create my own lab.

 

please advise.

The most important part of this issue is that you are using a layer 2 switch and have created multiple vlans. To route between vlans you need a layer 3 device (could be a router or could be a layer 3 switch).

 

The other part of the issue is that you have created 3 vlans and associated addresses with them. Your PC is in a different subnet so logically it should be in a fourth vlan. And you need a layer 3 device to route between your PC and the switch subnets/vlans.

you are using L2 switch so the best way that you can ping between different vlans is "router on a stick".

you can change the ip address on your pc for example to 10.0.1.2 255.255.255.0 and 10.0.1.1 as default gateway to establish connectivity to vlan 101. It seems that you set ip address on your wireless card, you must set it on your ethernet card.

thanks everyone... I have the below sets of switches and routers at disposal...

2651XM; 2621XM; 2620XM; 2691; 1670; 2950-12/24/48

could you please advise of a lab for my CCNA

you can use below lab which is covering almost whole ccna exam concepts. 

but establishing frame-relay in home lab requires more knowledge on networking, i recommend that you use GNS3-ER which now supports switch emulation too for frame-relay concepts.

However as far as i know, packet tracer is almost enough for ccna exam.

I do not know what GNS3-ER is. After google found some linki for GNS 3 and downloaded  GNS3 0.8.7.

 

Explored it and could not find the lab you have mentioned. I m a novice in networking and know only few basic commands
