Hello vmacnell
See my comments inline below.
I have a summit stack of 5 x460 switches and I recently purchased 2 additional ones. The new ones have a newer bootrom and software.
Depending on the age of the switch it will only support certain software levels? the only time code is not supported on a switch is when the switch has been End of Support which the 460 is not.
Is it reccomended to have the same software level on all switches in a stack? Yes all switches in a stack need to be on the same level of code and although not necessary to operate it is highly recommended to have the same image in the same container on every switch. i.e. primary or secondary. If the code is prior to 12.6 then all switches in a stack need to be on the same license level. 12.6 and higher only require the master capable switches to be on the same level.
If so I will only ever be able to run the highest supported version of my oldest switch? yes all switches can run the latest version of software
You can only get the bootrom's through support? I believe so I did not see it on the esupport page
When I enter the serial number in the support site it only shows me the supported software versions right? no the esupport will only show versions you are entitled to based on your service level. If you have TAC/OS and higher you should have access to the latest code for your switch. IF I can find a common version that shows for all my switches that would be the one to install? Yes I would still contact TAC to verify. The limited warranty allows you to have access to the version of code that is available when your switch ships. That may not be the version that the switch ships with due to when the manufacturing line is updated. TAC should be able to check the serial number and give recommendations.
Hope that helps
