config erps raps_vlan timer
an intermittent defect. This timer is used during the protection switching process when a link
failure recovers. It is only used by the RPL owner. When the RPL owner in protection state
receives R-APS PDU with an NR flag, it will start the WTR timer. The RPL owner will block
the original unblocked RPL port and start to send R-APS PDU with an RB flag after the link
recovery is confirmed within this period of time.
