MX10008 LC9600 fabric degraded / "attempt fabric healing" on 23.4R2-S5

  • 1.  MX10008 LC9600 fabric degraded / "attempt fabric healing" on 23.4R2-S5

    Posted 6 days ago

    Hi all,

    We observed a fabric-related issue on an MX10008 with LC9600 running 23.4R2-S5.

    Observed symptoms:

    - FM_LINK_ERROR on fabric links

    - CRC error history on fabric/internal links (RE0 spmb0)

    - CHASSISD_FM_FABRIC_DEGRADED

    - "DPCs are seeing grant timeouts; System is blackholing"

    - "Need to attempt fabric healing"

    - FPC offline/online action triggered for healing

    Question:

    I checked PR Search and release notes, but I couldn't find a PR that clearly matches this exact symptom pattern on MX10008/LC9600 running 23.4R2-S5.

    Has anyone seen a similar case before, and if so, is it associated with any known PR?

    Thanks.
