  • 1.  ERPSv2 Pending States as Ring Node on ACX

    Posted 03-21-2022 10:13
    Hi everyone,

    I have a problem with ERPSv2 on ACX7100.
    i am using three node ring , other 2 nodes are from other vendor.

    ERPS Topology


    I set ACX as Ring Node (not RPL Owner), the ERPS is not running.

    show protection-group ethernet-ring node-state
    Ethernet ring   APS State  Event       RPL Owner  WTR Timer  WTB Timer  Guard Timer  Operation state
    RING1           pending    NR          No         disabled   disabled   disabled     operational
    ​

    show protection-group ethernet-ring interface
    
    Ethernet ring port parameters for protection group RING1
    
    Interface  Control Channel  Direction  Forward State  RPL End  SF     Admin State
    et-0/0/0   et-0/0/0.0       east       discarding     No       Clear  IFF ready
    et-0/0/1   et-0/0/1.0       west       forwarding     No       Clear  IFF ready
    ​

    show protection-group ethernet-ring aps
    Ethernet Ring   Request/state  RPL Blocked  No Flush  BPR  Originator  Remote Node ID
    RING1           NR             No           No        0    Yes         NA
    ​

    My configuration :

    set protocols protection-group restore-interval 1
    set protocols protection-group guard-interval 10
    set protocols protection-group hold-interval 0
    set protocols protection-group ethernet-ring RING1 level 7
    set protocols protection-group ethernet-ring RING1 compatibility-version 2
    set protocols protection-group ethernet-ring RING1 east-interface control-channel vlan 1100
    set protocols protection-group ethernet-ring RING1 east-interface control-channel et-0/0/0.0
    set protocols protection-group ethernet-ring RING1 west-interface control-channel vlan 1100
    set protocols protection-group ethernet-ring RING1 west-interface control-channel et-0/0/1.0
    set protocols protection-group ethernet-ring RING1 control-vlan 1100
    set protocols protection-group ethernet-ring RING1 data-channel vlan 1000
    set protocols protection-group ethernet-ring RING1 data-channel vlan 1200-1209​

    I have disabled RSTP.

    When i test to set ACX as RPL owner : ERPS running normally.
    Please need your help to solve this issue.
