It implements IEEE 802.1AB Link Layer Discovery Protocol and also speaks several older vendor discovery protocols, making it a practical bridge between standards-based and legacy network-neighbor discovery. ### 项目历史 The project is maintained as a daemon, lldpd, plus command-line clients such as lldpcli and lldpctl. The upstream README describes support for receiving and sending LLDP frames, an SNMP subagent for net-snmp, partial LLDP-MED support, and operation on FreeBSD, GNU/Linux, macOS, NetBSD, OpenBSD, and Solaris. The public GitHub release history includes lldpd 0.7.8 on May 28, 2014 and the NEWS file records the 1.0.0 series before later 1.0.x maintenance releases. Later entries show steady maintenance around network interface handling, security hardening, protocol parsing, and platform support. ### 采用历史 lldpd fits the operational niche where servers, appliances, lab machines, and network-attached Unix systems need to advertise and inspect their Layer 2 neighbors without relying on a switch-vendor agent. Its support for CDP, FDP, SONMP, and EDP helped it coexist with older proprietary discovery environments while LLDP became the vendor-neutral default. ### 使用方式 In normal use, lldpd runs as a daemon that sends and receives discovery advertisements, while lldpcli queries and configures the daemon. Operators use it to identify switch ports, chassis IDs, VLAN hints, management addresses, capabilities, and neighboring devices directly from a host. Its package-manager value is strongest on Unix-like systems where a small daemon can make server-to-switch topology visible without installing a full network-management stack. ### 为什么软件包爱好者会关心 lldpd is the kind of infrastructure package that quietly saves debugging time: after installation, a host can explain what it is connected to at Layer 2. For package nerds, it is also a compact example of a daemon packaged with privilege separation, service integration, SNMP hooks, protocol compatibility, and OS-specific network plumbing. ### 时间线 - 2005: IEEE published the 802.1AB standard for station and media access control connectivity discovery. - 2014-05-28: lldpd 0.7.8 appeared in GitHub releases. - 2026-05-14: lldpd 1.0.22 appeared in GitHub releases with security and protocol parsing fixes. ### Related projects - IEEE 802.1AB defines the LLDP standard that lldpd implements. - CDP, FDP, EDP, and SONMP are vendor discovery protocols that lldpd can interoperate with. - net-snmp is related through lldpd's AgentX/SNMP subagent support. ### 来源 - - - - - - - ## 安全说明 formula declares a Homebrew service. - **Geiger 风险:** orange / 中 - formula declares a Homebrew service ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
