remote IP subnet
A secondary LAN attached to the network through an IP tunnel.
root
The access point with the highest root priority becomes the root of the
network spanning tree. If the root becomes inactive, the remaining root
candidates negotiate to determine which access point becomes the new
root. The root can be used to set system-wide flooding and RF
parameters. The root is also the only node in the network that can
originate IP tunnels.
root port
The access point port that provides the inbound connection to the
spanning tree. The root port provides a link to a parent access point.
Note that a root access point does not have a root port.
root subnet
The Ethernet segment to which the root access point connects, also
known as the primary LAN.
router
A software and hardware connection between two or more
subnetworks that permits traffic to be routed from one network to
another on the basis of the intended destinations.
secondary bridging
Ethernet bridging on a non-root port. An access point that is the
designated bridge for a secondary LAN uses secondary bridging to
bridge frames to and from the secondary LAN on a non-root Ethernet
port.
secondary LAN
Any Ethernet LAN that is not the primary LAN. A single access point
functions as the designated bridge for a secondary LAN. The designated
bridge attaches the secondary LAN to the network through a radio link
or an IP link. Primary and secondary LANs are both distribution LANs.
SNAP
A protocol extension typically used by Appletalk networks.
