Owner request: finding where a host is plugged in from a MAC or IP is a must,
and BGP peer monitoring is wanted.
L2 job (internal/l2): a job of its own, off the 60 s poll path (its sessions
are path "l2"), walks BRIDGE-MIB, Q-BRIDGE-MIB, CISCO-VTP-MIB (a per-VLAN
context walk, enabled by the cisco-ios profile flag l2.per_vlan_context, not by
detection) and the IP-MIB neighbour tables (IPv4 ARP and IPv6 ND, IPv4-only
fallback) every l2.interval, with its own concurrency cap and a per-device
deadline. It yields to the poller like the rollup job, and a device that times
out is skipped for the cycle, counted and named on /poller/health. Migration 14
adds fdb_entries, arp_entries, vlans and l2_walks with first/last-seen history,
batched upserts, daily pruning by last_seen (l2.keep) and backup coverage.
API (additive): /l2/search ranks edge ports first (a port is an uplink above
l2.edge_max_macs MACs, with an LLDP neighbour, or as a LAG), plus the device
fdb/arp/l2/l2-ports tables and /interfaces/{id}/macs; vendor and mac_kind are
computed at query time from the optional registry.
BGP: profiles label peer rows by decoding the table index (index_label.layout),
so each peer, IPv4 or IPv6, is one component whatever MIB feeds it; AS, local
AS, router id and description are component attributes, never labels.
CISCO-BGP4 (cisco-ios, cisco-nxos), Juniper BGP4-V2 and Arista BGP4V2 replace
the optional generic BGP4-MIB metrics, which edgeos, fortigate, pfsense and vyos
switch on. /bgp/peers lists sessions down first. The built-in rule
bgp_peer_down (critical, not established for 2 minutes) fires only where a
policy binds it; its notification names the peer's AS and description.
Fixtures are generated (Q-BRIDGE with IPv4/IPv6 neighbours, BRIDGE-MIB only,
Cisco per-VLAN contexts via a new simagent contexts feature) and checked
against real LibreNMS recordings. DEVIATIONS 50-55 record the departures.

Profiles gain category/label/of/display/scale_by/sentinels/enum_state and component_attrs;
every pollable non-interface metric is annotated and an orphan test enforces it. New routes
GET /devices/{slug}/metrics, /metrics/graph and /printers; printer supply type/colour read at
discovery into device_components.attrs; printer_supply_empty alert; supply_replaced audit event;

Discovery re-matches unpinned devices every run and at startup; an admin can pin a
profile (PUT /devices/{slug} profile, GET /profiles, DeviceView profile_pinned and
profile_match). Rows on the device list, interface search and poller health navigate on
click and Enter.
