During the first service boot after upgrade to EFA, EFA queries the SNMP and NTP configuration on the device. These configurations persist in the database, which is managed by EFA.
Breakout interfaces and interfaces that are in admin-state down, with non-auto speed or non-default MTU values, persist in the database and are managed by EFA
