Glossary
root access point
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 IP subnet
Also called the home IP subnet and primary LAN. The IP subnet that
contains the root access point. If wireless end devices need to roam
between IP subnets, each end device needs to have an IP address from the
root IP subnet.
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 port.
secondary LAN
Any LAN that is reached by routing traffic through an access point.
Wireless end devices that are communicating through a WAP comprise a
secondary LAN. A remote IP subnet is a type of secondary LAN.
SNAP
A protocol extension typically used by Appletalk networks.
SNMP (Simple Network Management Protocol)
SNMP is a popular network management protocol in the TCP/IP and
SPX/IPX protocol suite. SNMP allows TCP/IP and SPX/IPX sites to
exchange configuration and status information. It uses management
programs called "agents" to monitor network traffic. SNMP stores the
information it collects in the Management Information Base (MIB). Your
network administrator can use management software, such as MobileLAN
manager, interacting with the MIB to obtain information about network
activity.
