Details
oamd is an Ethernet-OAM protocol daemon. It is not an avm command but a Lantiq chipset command.
OAM (Operations, Administration, and Maintenance) is a protocol for managing and monitoring networks[1].
Ethernet-OAM injects OAM packets into the normal stream of data packets at layer 2[2].
oamd is used on these Lantiq DSL chipset driven models:
- AR9: 7312, 7320, 7330, 7330sl
- AR10: 3272, 7272
- VR9 TODO frontent: 7412
- VR9 VRX208 frontent: 3370, 3390, 3490, 7360sl, 7360v1, 7360v2, 7362sl, 7490
- VR9 VRX220LD frontent: 7430
- VR10 VRX318 frontend: 7560, 7580
- VR11 VRX518 frontend: 6890v1, 6890v2, 7510, 7520, 7530, 7590
The inclusion of oamd in 6850lte fw 7.26 was a mistake.
- AR9, AR10 have builtin DSL frontends
- VR9, VR10, VR11 have external DSL frontends driven by network SoCs
oamd is included for Lantiq DSL frontends up to VRX500 family, regardless of which network SoC drives them.
fw 7.29 help:
fritz3:/var/media/ftp $ oamd -h Usage: oamd [options] -h, --help Print help (this message) and exit
Examples
oamd is started in dsl_notify.sh fw 7.39 like this:
modprobe ltq_eth_oam_handler ethwan=ptm0 # 7520 / 7530 modprobe eth_oam_handler ethwan=ptm0 # others ifconfig eoam up oamd -ieoam -D
First the Ethernet-OAM packet multiplexer module is loaded to start oamd at its separate interface,
Events
Daily updated index of AVM-Events and AVMIPC-Datastore nodes affecting this command. Last update: 2023-12-10 05:13 GMT.
The owners of Event-Sinks and Event-Sources are manual research, which may be incomplete or even wrong.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.
