Details

lan0 is the internal ARM modem interface on Puma6 / Puma7 models.
It is the CMCI (Cable Modem to CPE Interface) ISP configuration interface, which is routed to a separate virtual connection.
It has the hardcoded IP 192.168.100.1 (defined by the DOCSIS specification) and uses the usb_rndis_mac MAC address.

It serves the ATOM Webinterface on Port-80-tcp and Port-443-tcp, which is proxied by pumaglued.
Optionally Port-8089-tcp could be forwarded for TR-069, also proxied by pumaglued.
Besides this snmp_agent_cm is also listening on this IP, on Port-161-udp and Port-162-udp.

Excerpt from showdsldstat of a DOCSIS connection with separate virtual connections for inet, voip and lan0:

RBE is routed bridge encapsulation, a Cisco implementation of bridged Ethernet over ATM with a separate broadcast domain
for every ATM circuit. It provides the multiplexing of the virtial connections.

Connections 0: (inet) and 1: (voip) use the sync_group sync_cable and both route to the erouter0 interface.
Connections 2: (lan0) uses the sync_group sync_lan0 and "routes" to the lbr0 interface, the lan0 bridge.

Dependencies

Daily updated index of all dependencies of this interface. Last update: GMT.
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.

The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.

Missing Supportdata

The data in this article is incomplete due to missing Supportdata-Probes for the models listed below.
If you own any of these models and would like to help then please get in touch.
