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.
Revertive mode- When revertive is enabled, the traffic link is restored to the working transport link.
When revertive is disabled, the traffic link is allowed to use the RPL, after recovering from a failure.
When both the global state and the specified ring ERPS state are enabled, the specified ring will
be activated. STP and LBD should be disabled on the ring ports before the specified ring is
activated.
The ring cannot be enabled before the R-APS VLAN is created, and ring ports, RPL port, RPL
owner, are configured. Note that these parameters cannot be changed when the ring is activated.
In order to guarantee correct operation, the following integrity will be checked when the ring is
enabled and the global ERPS state is enabled.
1. R-APS VLAN is created.
2. The Ring port is the tagged member port of the R-APS VLAN.
3. The RPL port is specified if RPL owner is enabled.
