Adds LLDP (Link Layer Discovery Protocol) topology discovery capability to the agent for local network neighbor detection. New Features: - LLDP-MIB walker for discovering network neighbors via SNMP - New LLDP_TOPOLOGY job type for topology discovery jobs - Automatic IPv4 and IPv6 management address parsing - Bulk neighbor discovery with full port information Protocol Buffers: - Added LldpTopologyResult message for topology data - Added LldpNeighbor message for individual neighbor info - Extended JobType enum with LLDP_TOPOLOGY (value 5) Implementation: - lldp.go: LLDP discovery logic with SNMP walking - agent.go: Job dispatch and result channel handling - Updated handleMessage signature to support LLDP results - Result sent to Phoenix via "lldp_topology_result" event LLDP-MIB OIDs: - 1.0.8802.1.1.2.1.3.3.0 (lldpLocSysName) - 1.0.8802.1.1.2.1.3.7.1.4 (lldpLocPortDesc) - 1.0.8802.1.1.2.1.4.1.1.7 (lldpRemPortId) - 1.0.8802.1.1.2.1.4.1.1.8 (lldpRemPortDesc) - 1.0.8802.1.1.2.1.4.1.1.9 (lldpRemSysName) - 1.0.8802.1.1.2.1.4.2.1.3 (lldpRemManAddr) This enables the Phoenix web application to dispatch LLDP discovery jobs to agents for local neighbor detection, reducing SNMP load on the Phoenix server and improving discovery performance. |
