VSX config sync bug?

  • 1.  VSX config sync bug?

    Posted Jun 27, 2022 11:39 PM
    Hello,
    i have following situation:
    8325-1# sh vsx status
    VSX Operational State
    ---------------------
    ISL channel : In-Sync
    ISL mgmt channel : operational
    Config Sync Status : configuration_sync_missing_reference
    NAE : peer_reachable
    HTTPS Server : peer_reachable

    Attribute Local Peer
    ------------ -------- --------
    ISL link lag256 lag256
    ISL version 2 2
    System MAC 02:01:00:00:01:00 02:01:00:00:01:00
    Platform 8325 8325
    Software Version GL.10.09.1020 GL.10.09.1020
    Device Role primary secondary

    8325-1# sh vsx status config-sync
    Admin state : Enabled
    Operational State : Operational
    Error State : Missing reference error
    Recommended remediation : A. Execute 'show running-config vsx-sync peer-diff' to determine which lines did not sync correctly on secondary
    B. Identify the configuration that is missing from secondary and manually fix via CLI.
    Current time : Mon Jun 27 15:36:03 2022
    Last sync time : Mon Jun 27 15:10:41 2022

    8325-1# show running-config vsx-sync peer-diff
    No difference in configs.


    is it some known issue ?

    Regards,
    Mladen

    try the command vsx-configmate
    and shared the output.
    If no reported problem, I would  recommend to check the VLAN presence on secondary.

    And vlans:
    8325-1# sh vlan summary
    Number of existing VLANs : 126
    Number of static VLANs : 126
    Number of dynamic VLANs : 0
    Number of port-access VLANs: 0

    8325-2# sh vlan summary
    Number of existing VLANs : 126

    Have you tried to manually/visually do a diff between both running configurations (VSX Primary versus VSX Secondary)? if so, are there any notable differences?

    Hello,
    There is many config differences because physical ports are different (it isn't fully redundant setup unfortunately).

    It should show up at the diff command but i would manually check the LAG interfaces (multi-chassis) that are even.

    Technically speaking any differences in VSX LAG (Multi-Chassis LAG) - such as VSX LAG missing - should have been explicitly reported on the events:

    As example:

    2021-01-10:19:00:22.026340|vsx-syncd|7602|LOG_INFO|AMM|-|Configuration sync update : Missing Reference Error: Could not find Port lag30 on secondary VSX database.

    I  looks like ospf configuration on interface present on primary but not on secondary makes problems:
    Test on interface without ospf before:

    8325-1# sh run interface lag 24
    interface lag 24
    no shutdown
    ip address 1.2.1.1/24
    ip pim-sparse enable
    exit
    8325-1#
    8325-1# conf t
    8325-1(config)# interface lag 24
    8325-1(config-lag-if)# ip ospf 10 area 0
    8325-1(config-lag-if)# no ip ospf passive
    8325-1(config-lag-if)# end

    A few moments later :)

    8325-2#
    2022-06-29T12:34:21.151018+0200 vsx-syncd[6162] <INFO> Event|7602|LOG_INFO|AMM|-|Configuration sync update : VSX configuration-sync updated database

    And
    8325-1# show running-config vsx-sync peer-diff
    No difference in configs.

    Should it be a bug or not ?

    Could you confirm you have configured "vsx-sync ospf" under vsx ?

    Do you have non-LAG interface that have OSPF config synchronized ? On non-LAG, it should work. If not, then this is a regression => TAC.
    On L3 LAG interface, I have to check.
