I'm upgrading the IOS of my 4500X switches to version 3.6.6E and planning to run the VSS.
Do I need to upgrade ROMMON or not? Didn't find clear information in below release notes:
My currently running ROMMON version is 15.0(1r)SG12.
I look forward to hearing from you. Thanking you all in advance.
Thanks Leo, can you please check the below syntax for upgrading 4500X boxes:
Do I need to add the forward slashes '/' ? like the syntax below:
1) copy tftp://<TFTP IP address>/<filename.bin> bootflash:
(2) boot system flash bootflash:/<filename.bin
(3) no boot system flash bootflash:/<old filename.bin
Kindly, let me know which one is correct. Procedure 1 or 2?
Please also tell me that with config-register 0x2102 if the switch will boot from old IOS if new one fails to boot.
But then which statement switch will read to boot? I thought this has to be done by the configuration register.
BTW Leo did you check forward slashes are needed in the syntax or upgrade procedure is exactly the same like 4500E. check the procedure(1) that I shared earlier and let me know if that is correct. I don't want the switches to go into ROMMON mode :(
