Licensing Requirements and Limitations for ERPS
Involved Network Elements
Other network elements are required to support ERPS functions.
Licensing Requirements
ERPS is a basic function of the switch, and as such is controlled by the license for basic software functions. The license for basic software functions has been loaded and activated before delivery. You do not need to manually activate it.

Feature Limitations
In ERPSv2, sub-rings can interlock in multi-ring topologies. The sub-rings attached to other sub-rings must use non-virtual channels.
A VLAN cannot be mapped to multiple MSTIs. If you map a VLAN that has already been mapped to an MSTI to another MSTI, the original mapping will be deleted.
To configure the mapping between an ERP instance and a MUX VLAN, please configure the principal VLAN, subordinate group VLANs, and subordinate separate VLANs of the MUX VLAN in the same ERP instance. Otherwise, loops may occur.
A port can be added to a maximum of two ERPS rings.
An ERPS-enabled port needs to allow packets of control VLANs and data VLANs to pass through, so the link type of the port must be configured as trunk or hybrid.
Flush-FDB packets for updating MAC addresses cannot be separately sent, so do not configure a direct link between two upstream nodes as the RPL.
If the virtual-channel enable command is used to set the VC mode for RAPS PDU transmission in a sub-ring, ensure that the control VLAN of the major ring is used to transmit only the RAPS PDUs of the sub-ring. Otherwise, attacks may use bogus RAPS PDUs of the sub-ring to form loops or even fault in the major ring.
ERPS cannot be applied simultaneously with Selective QinQ, VLAN mapping, or Port Security on a port.
Before adding a port to an ERPS ring, ensure that the STP/RSTP/MSTP/VBST or Smart Link is not enabled on the port.
ERPS packets may be discarded by the interface with multicast traffic suppression enabled using the storm suppression multicast command.
