CRC Error - VSX

  • 1.  CRC Error - VSX

    Posted 21 days ago

    Hello,
    I am relatively new to networking and Aruba and need your help.
    I have 2 core switches 8360-48Y6C with FW 10.13.1000 and VSX configured. 

    All access switches are connected with a LAG (lag1 and lag2) and 2 uplinks each to the core switches. 

    However, if 1 uplink connection is removed in a lag, I have the timeouts:


    Unfortunately, I can't see anything about the problem in the log.

    At the same time, I also see CRC errors from the core switch to the firewall.

    Both uplink lags (lag1 and lag 2 on both switches to the firewalls) are up (lag1 is lacp-block because I have an active/passive cluster)

    Config Lag:

    My setup:

    sh vsx status
    VSX Operational State
    ---------------------
      ISL channel             : In-Sync
      ISL mgmt channel        : operational
      Config Sync Status      : In-Sync
      NAE                     : peer_reachable
      HTTPS Server            : peer_reachable
     
    Attribute           Local               Peer
    ------------        --------            --------
    ISL link            lag254              lag254
    ISL version         2                   2
    System MAC          02:00:00:00:00:01   02:00:00:00:00:01
    Platform            8360                8360
    Software Version    LL.10.13.1000       LL.10.13.1000
    Device Role         primary             secondary
    sh vsx brief
    ISL State                              : In-Sync
    Device State                           : Peer-Established
    Keepalive State                        : Keepalive-Established
    Device Role                            : Primary
    Number of Multi-chassis LAG interfaces : 14

    What did I do? 
    I have replaced the cables
    I have replaced all transceivers

    I have changed the ports on the switch

    Does anyone else have an idea where I should look?

    Thanks
