    Some mirrored IS-IS fields are <strong>read-only</strong> (not carried by the NSO write path):
    per-instance timers/LSP/overload-on-startup/TE/distance/paths/bandwidth/attached-bit,
    per-interface hello-auth &amp; csnp/retransmit/lsp-interval &amp; mesh-group, level
    default-metric/preference/auth, and all interface-levels, settings, segment-routing,
    prefix-SIDs and SRv6 locators. Editing them in NetBox does <em>not</em> reach the device —
    the IS-IS object pages list the exact fields.
