The message "LSP ERROR!" does not indicate a hardware failure. This may be displayed on a 7000 Series or 8000 Series FirePOWER device when the Link State Propagation (LSP) is triggered.
Link State Propagation (LSP) is an option for inline sets in bypass mode that automatically brings down the second interface in a pair when one of the interfaces in an inline set goes down. When the down interface comes back up, the second interface automatically comes back up. In other words, if the link state of a paired interface changes, the link state of the other interface changes automatically to match it.
