snmpd reports net-snmp's generic Linux sysObjectID (.1.3.6.1.4.1.8072.3.2.10) unless told otherwise, so a manager cannot tell an OpenWrt device from any other net-snmp host without an extra query, typically against the distro extend. Set sysObjectID in the default config to .1.3.6.1.4.1.66510.3.1 (openwrtDevice in OPENWRT-MIB, under OpenWrt's IANA enterprise number). snmpd.init already passes the option through. Being in the default config, it only reaches new installs and can be removed like any other option. Bump PKG_RELEASE to account for the package configuration change.

snmpd reports net-snmp's generic Linux sysObjectID (
.1.3.6.1.4.1.8072.3.2.10) unless told otherwise, so a network manager cannot tell an OpenWrt device from any other net-snmp host without an extra query (typically adistroextend). SetsysObjectIDin the default config to.1.3.6.1.4.1.66510.3.1(openwrtDevicein OPENWRT-MIB, under OpenWrt's IANA enterprise number 66510).snmpd.initalready passes the option through.It is only a change to the default
snmpd.conf, so it reaches new installs; existing configurations are untouched and can drop the option like any other. LibreNMS uses it to detect OpenWrt without a query (librenms/librenms#19347, where a maintainer asked to avoid ansnmpgetduring discovery); the OPENWRT-MIB itself ships with #30547.Maintainer: @stintel
