    Hi, 

    We have a SRX chassis cluster which are throwing input errors and we want to replace the cable. Can we replace the fabric link without causing any traffic disruption / failover if the nodes are healthy? 
    Is there anything we need to verify before doing that?

    show interfaces ge-0/0/0 extensive | match err 
      Link-level type: 64, MTU: 9014, Link-mode: Full-duplex, Speed: 1000mbps, BPDU Error: None, MAC-REWRITE Error: None, Loopback: Disabled, Source filtering: Disabled,
      Input errors:
        Errors: 12600527, Drops: 0, Framing errors: 12600527, Runts: 0, Policed discards: 0, L3 incompletes: 0, L2 channel errors: 0, L2 mismatch timeouts: 0, FIFO errors: 0,
        Resource errors: 0
      Output errors:
        Carrier transitions: 3, Errors: 0, Drops: 0, Collisions: 0, Aged packets: 0, FIFO errors: 0, HS link CRC errors: 0, MTU errors: 0, Resource errors: 0

        FIFO errors                              0                0
        Output packet error count                                 0
        Flow error statistics (Packets dropped due to): 
          Incoming NAT errors:               0
          User authentication errors:        0

    Same with ge-13/0/0 output too

    Appreciate any help.

    Hi,

    It can be replaced. However, ensure that all RGs are running on one node and no disruption on control link while replacing fab links.
