Wich is the right firmware for our 4506 switches

Hi, together,

we have two switches 4506 and we wish upgrade the firmware. But at the moment I find many actual versions

of IOS Software for that Switch and I don't no, what is the correct version?

For the Supervisor Engine V I found:





Can I upgrade this switches with the CNA or it is necessary to use the CLI?

Hope anybody can help.

Thanks Michael.

Re: Wich is the right firmware for our 4506 switches

i would recommend ypou to go for the latest IOS as it has fix to most of the known issues and go for the


Release Date: 13/Nov/2009

Size: 16663.78 KB    (17063708 bytes)

Minimum Memory: DRAM:256 MB    Flash:64 MB

If i would have been in your place i would go for CLI ios upgrade refer to the link given below to do an IOS upgrade :-

Hope this helps.




Re: Wich is the right firmware for our 4506 switches

   The "EWA" train is a dead or EOL train  and further patches and development are not scheduled, go to one of the  newest "SG" releases  within your same feature set on the switch.

Re: Wich is the right firmware for our 4506 switches

Hi Michael

I agree 100 % with Varun & Glenn.. I just ran a software advisor, and saw 12.2(53) SG1 suitable for the modules you specified.. generally for 4306 GBIC modules, you will not have issues finding an IOS, unlike for other advance services modules.. If your device has smartnet support, you can get the latest software free with the same maintenance release... if you need feature upgrade -> say enterprise base -> enterprise ipservices etc, you might have to buy appropriate licenses from cisco. you can look at the device datasheet to know the exact part number.. In anycase if you are just upgrading a maintainance release within the same major version, its free....

Hope this helps.. All the Best

Re: Wich is the right firmware for our 4506 switches

Hi, together,

thanks for your help. I have made the firmware upgrade on last sunday with the firmware file cat4500-ipbase-mz.122-53.SG1.bin. No problems.
