ERPS

The ERPS (Ethernet Ring Protection Switching) instances are configured here.

Caution

Caution

When configuring ERPS, we recommend that you allow Egress of only the control VLAN (Virtual LAN) and protected VLANs. Failure to do this could cause open loop flooding.
Object Description
Delete This box is used to mark a ERPS for deletion in next Save operation.
ERPS ID The ID of the created Protection group. It must be an integer value 1 – 64. The maximum number of ERPS Protection Groups that can be created is 64. Click on the ID of an Protection group to enter the configuration page.
Port 0 This will create a Port 0 of the switch in the ring.
Port 1 This will create "Port 1" of the switch in the Ring. As interconnected sub-ring will have only one ring port, "Port 1" is configured as "0" for interconnected sub-ring. "0" in this field indicates that no "Port 1" is associated with this instance
Port 0 SF MEP The Port 0 Signal Fail reporting MEP.
Port 1 SF MEP The Port 1 Signal Fail reporting MEP. As only one SF MEP is associated with interconnected sub-ring without virtual channel, it is configured as "0" for such ring instances. "0" in this field indicates that no Port 1 SF MEP is associated with this instance.
Port 0 APS MEP The Port 0 APS PDU handling MEP.
Port 1 APS MEP The Port 1 APS PDU handling MEP. As only one APS MEP is associated with interconnected sub-ring without virtual channel, it is configured as "0" for such ring instances. "0" in this field indicates that no Port 1 APS MEP is associated with this instance.
Ring Type Type of Protecting ring. It can be either major ring or sub-ring.
Interconnected Node Interconnected Node indicates that the ring instance is interconnected. Select the checkbox to configure this.
  • Yes: indicates it is an interconnected node for this instance.
  • No: indicates that the configured instance is not interconnected.
Virtual Channel Sub-rings can either have virtual channel or not on the interconnected node. This is configured using Virtual Channel checkbox.
  • Yes: indicates it is a sub-ring with virtual channel.
  • No: indicates, sub-ring doesn't have virtual channel.
Major Ring ID Major ring group ID for the interconnected sub-ring. It is used to send topology change updates on major ring. If ring is major, this value is same as the protection group ID of this ring.
Alarm There is an active alarm on the ERPS.
