C4500-x not supporting GLC-T SFP

[Chala]

My cisco C4500-x switch is not supporting GLC-T SFP transciever. the iOS version of the switch is (cat4500e -UNIVERSALK9-M), Version 03.08.01.E. I check the compatablity of the SFP with the switch and found out the iOS version is too old to support the SFP.

Is it really the ios version problem? if yes, how do I upgrade it ?

[Chala]

what shall I do then.

Please advice!

do 

boot system flash bootflash:/<YOU-FILE-NAME-WITH-EXTENSION>

[Chala]

then what is next

could you please share me the commands follow up

[M02@rt37]

@Chala 

(config)#no boot system

(config)#boot system flash bootflash:/cat4500e-universalk9.SPA.03.08.01.E.152-4.E1.bin

(config)#exit

#wr

[Chala]

The highlighted part should be the new ios file name. right ?

[M02@rt37]

yes sir!

Considering that new IOS is on your bootflash...

[Chala]

Successfully upgraded the iOS but still the SFP is not working.

@Chala 

Consider also upgrading the ROMmon.

Check the datasheet about known issues attached to that version (IOS + ROMmon)

I have a Cisco 4500X, and it has an IOS image (cat4500e-universalk9.SPA.03.08.01.E.152-4.E1.bin). I tried to upgrade to the latest version with the K9 feature, but the upgrade process failed. Then, I tried upgrading the iOS (cat4500e-universal.SPA.03.11.11.E.152-7. E11) without the K9 feature, and this upgrade process finished successfully. But I couldn't use such as SSH, Encryption Key, and VPN. Finally, I attempted to revert to the previous image because I want to use the K9 feature, but the upgrading process (Downgrade to previous one) is failed. I couldn't back to the previous image. Can you help please.

Why did it fail?  Is it because the BIN file is corrupt?

Why not download 3.11.11 with K9?

Clean up your bootvariable

Take care  boot field is 0x0, mean: boot the operating system manually with the boot command. 

[Chala]

Could you share me the steps and commands to change the Configuration register is 0x0 to 0x2102.

Thanks for your support
