4006 Cisco Switch Advice

We bought a 4006 switch with supervisor engine 2. I believe it is using CAT OS. This we want to change so that we use IOS instead of CAT OS. Is this possible ? If so, what will I need for the change ? here is the details of the modules we currently have on the 4006 switch



Ios is cisco4000-k9.6.2.3

Re: 4006 Cisco Switch Advice

I think this is not possible. You can run IOS only on Supervisor 3 and up.

Re: 4006 Cisco Switch Advice

Thanks for your inforamtion. Can I change from Supervisor engine 2 to supervisor engine 3 ? What sort of module/IOS will I need to buy ?


Re: 4006 Cisco Switch Advice

You'd need to buy a Supervisor 3 module to replace your Supervisor 2. Presumably the Sup3 will come with IOS installed.

Re: 4006 Cisco Switch Advice

You might want to consider Sup2 Plus which runs IOS as well

Re: 4006 Cisco Switch Advice

Thanks for your useful link. Is there a way Cisco can replace the current module that we have or we have to do it with the reseller ? By the way what is the cost of this Supervisor Engine 2 Plus module ? and is there anything else that is needed to be replace on the 4006 switch or just simply remove the Supervisor Engine 2 module and replace it with the Engine 2 Plus module (Plug and Play)


Re: 4006 Cisco Switch Advice

I think the question becomes why do you think you need to run IOS versus Catos when the current setup runs all the hardware you have installed . Sounds like you could save yourself some money and just use what you have . If you are doing strictly layer2 stuff then I actually find Catos easier to work with .

Re: 4006 Cisco Switch Advice

Thanks for the good idea glen. The reason why we want to change to IOS is because we are familiar with IOS than CAT OS. All our current switches and routers use IOS. We also want to standardise to using IOS. Will there be conflict in configuration when we incoporate IOS and CAT OS ?


Re: 4006 Cisco Switch Advice

Catos is a different command set than the ios versions (actually easier once you know it) and there should not be a problem operational wise connecting back to a ios device , you just have to figure out what the paramters are on each side . CCO has a lot of examples on how to configure catos on one side to a ios device on the other side if that's what you are concerned about . Good luck.....
