Problem Description
A downgrade of the ROM monitor (ROMMON) on an ASR1002-X with system Version V07 or later to a ROMMON version earlier than Version 16.2(1r) causes the management port to malfunction. An ASR-1002-X with system Version V06 or earlier does not have this minimum ROMMON requirement.
Background
Due to a Cisco supplier End-of-Life, Cisco will use a newer component which requires a new ROMMON version.
Problem Symptom
A downgrade of the ROMMON on an ASR1002-X with system Version V07 or later to a ROMMON version earlier than Version 16.2(1r) causes the management port to malfunction.
Workaround/Solution
For ASR1002-X systems with system Version V07 or later, do not downgrade the ROMMON to a version earlier than Version 16.2(1r).
