The maintenance mode feature allows network administrators to perform switch servicing with minimal traffic disruption. When an interface enters maintenance, the rate monitoring stage waits for traffic to drain below a configured threshold before transitioning the interface into maintenance. However, if traffic does not drain — for example, due to insufficient network redundancy or routing constraints — the interface may remain in the "Entering Maintenance" state indefinitely, potentially blocking scheduled maintenance operations.
