2950 IOS Upgrade

dcanady55 · ‎10-10-2013

Hello,

I apologize in advance for what probably is very basic questions. I am new to Cisco and the network side of things

I have a 2950 24 port switch and I wanted to practice updating it's IOS using my TFTP server. It has no config on it currently, I gave vlan1 an IP address and subnet mask. I couldn't ping it after I put it on the network I am wondering if there's anything else I need to configure for my to just get it on the network so that I may play around with it? Also, I'm assuming there's a way to copy the old IOS using a console cable I haven't been able to find anything yet on how to do this I would like to learn that as well if someone could point me in that direction as well.

Thanks,

I thought I would add a couple of things. I did make sure the vlan is not shut down and I did give it a default gateway.

Thanks,

Hello dcanady55.

You can copy the IOS using the console cable, however this procedure is so slow that you might want to copied through TFTP.

Anyways here's the procedure how to copy using the console cable.

In regards to the connectivity problem,

- Is your PC in the same vlan as the 2950?

- Is you PC able to ping other devices in the same vlan where the 2950 is configured?

- If they are not in the same vlan.. Did you configure a default gateway in the 2950?

- Are you able to ping the default gateway of the 2950 from your PC?

- Are you able to ping the default gateway of the 2950 from the 2950 itself.

Regards.

Hi Wilson,

Thanks for the quick reply. To give a little more background of how my lab is setup. The switch in question I have plugged into my core switch. I did change vlan 1 on my test switch to be in the same vlan as my pc. My pc is plugged into my core switch as well.

I can ping other devices from my pc just fine. I configured the default-gateway to be the same as my pc's gateway.

I can ping the default-gateway from my pc just fine. I cannot ping the gateway from the switch itself and I still cannot ping the switch from my pc. I am probably missing someting very simple.

THanks,

I did just make port 24 on the switch a switchport as I think this needs to be enabled.

Hi.

It seems the switch doesn't have any connectivity at all, make sure the port connected to the Core switch is properly configured and also that it's in spanning-tree forwarding.

Regards.

When I do a show IP int bri it shows that my vlan73 is down down and my uplink port 24 is up up. I am not sure how to enable vlan73 other than going into that interface and typing no shutdown which I have done.

glen.grant · ‎10-10-2013

You have to make sure "int vlan 1" is shutdown . You can only have a single active management address on a Layer 2 switch and i'm suspecting vlan 1 is the current active interface. Shutdown vlan 1 and then do a no shut on vlan 73 if that's what youi have chosen to use.

Hi, have you verified if the port that connects both switches are trunking correctly?

Use you a crossover UTP to the uplink?

The interface VLAN1 is up?

dcanady55 · ‎10-10-2013

I should of pointed out that the core switch is an HP so there may be some issues there.

Can you copy here your running-config?

There's not a lot to it.

Do you have the layer 2 vlan for vlan 73 created ? Do a show vlan and see if it shows up . Unless you are using a client /server setup make vtp transparent so you can see the vlans in your config.

dcanady55 · ‎10-10-2013

When I do a show vlan I do not see vlan 73. Not sure, I understand your question about " Do you have the layer 2 vlan for vlan 73 created ?" I went ahead and made the vtp transparent.

glen.grant · ‎10-10-2013

conf t

vlan 73 exit

then check your network.

You have not created the layer 2 vlan for vlan 73. All you created is the layer 3 SVI for managing the switch. So you have no path across your trunk for vlan 73 because the vlan is not created.
