Configuring ERPS ring member ports
Restrictions and guidelines
Perform this task on each node's ports intended for accessing ERPS rings.
ERPS ring member ports automatically allow packets from the control VLAN to pass through.
Do not enable Ethernet OAM remote loopback for ERPS ring member ports. This feature might cause a broadcast storm. For more information about Ethernet OAM, see "Configuring Ethernet OAM."
For faster topology convergence, use the link-delay command on ERPS ring member ports to set the physical state change suppression interval to 0 seconds. For more information about the link-delay command, see Layer 2—LAN Switching Command Reference.
You must configure ERPS ring member ports as trunk ports.
Do not assign an interface to both an aggregation group and an ERPS ring. If you do so, the interface does not take effect on the ERPS ring and cannot be displayed by using the display erps detail command.
Configuring ERPS ring member port attributes
Enter system view.
system-view
Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view.
interface interface-type interface-number
Configure the port as a trunk port.
port link-type trunk
By default, a port is an access port.
For more information about this command, see Layer 2—LAN Switching Command Reference.
Assign the trunk port to protected VLANs.
port trunk permit vlan { vlan-id-list | all }
By default, a trunk port is assigned only to VLAN 1.
For more information about this command, see Layer 2—LAN Switching Command Reference.
Disable the spanning tree feature.
undo stp enable
By default, the spanning tree feature is enabled.
For more information about this command, see Layer 2—LAN Switching Command Reference.
