Figure 59-1: Core distance hop-counts between domains
Links This is the distance (hop count) between a domain and the Core domain. The Core domain
has a Core distance of 0, and the maximum recommended Core distance in an AMF
network is 8.
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 AMF-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. For
more information on trunk mode see
“Configuring VLANs” on page 16.3 .
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 AMF-crosslink will automatically
put the port into trunk mode. A crosslink can be either a single link or a static aggregator.
