8 new rules (vendor=a10) wired into Network Equipment Parsing: LSN TCP/Session/ICMP per-user quota exceeded (critical - real service impact, drops new connections for that subscriber), BGP-4-MAXPFX prefix-limit warning, and admin session open/close/timeout/auth-success (aXAPI and CLI both covered by one pattern each). Unlike the CSV-report-derived rules, these are built directly from real captured A10 log output the user provided, so confidence is higher - closer to the accel-ppp rules' provenance. Multi-entry LSN lines (several 'ip(count)' pairs in one quota-exceeded message) only have their first pair extracted into fields; the full list stays in the raw message. Not live-verified - the user is bringing the target system up themselves this time rather than through the test container used earlier in this branch of work.
