AMF concepts
Links
AMF links are used to connect AMF nodes to AMF nodes in other AMF domains, and are
either uplinks or downlinks. Uplinks are used to connect a domain with a higher Core
distance (further from the Core) to a domain with a lower Core distance (closer to the
Core. Downlinks are used to connect a domain with a lower Core distance to a domain with
a higher Core distance.
AMF links are used to pass AMF management traffic between nodes, but can also be used to
carry other network traffic. Configuring an interface as an atmf-link will automatically put
the port into trunk mode. An AMF link must have at least one tagged VLAN, or have a native
VLAN defined. An AMF link can be either a single link or a static aggregator.
Crosslinks
AMF crosslinks are used to connect AMF nodes to other AMF nodes within the same AMF
domain. AMF master nodes must be connected using AMF crosslinks to ensure they are part
of the core domain. Configuring an interface as an atmf-crosslink will automatically put the
port into trunk mode. A crosslink can be either a single link or a static aggregator.
