after upgrading some 7K from 6.1 to 6.2.2 we encounter the following issue
interface go in xcvrInval state and nothing we do can change it unless changing to a fet or 1G spf.
The same optic in a 6.1 chassi is seen correctly.
xcvrInval is seen on any interface config, from fabricpath to a routed interface.
any advice would be welcome.
