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.
