Symptom
An unexpected port MTU is set after flapping an access port. When the fabric Layer 2 MTU policy is configured, the port MTU is calculated by 'fabricMtu + 22'. However, the MTU becomes 'fabricMtu + 44' after the port goes down and comes back up.
Conditions
This symptom maybe observed after flapping a front panel port.
Workaround
Reconfigure the fabric Layer 2 MTU policy.
