Glossary
remote IP subnet
Also called a secondary LAN. The IP subnet that does not contain the root access point,
but communicates with the primary LAN through an IP tunnel.
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.
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. A 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 wireless link or an wired link. Primary and secondary
LANs are both distribution LANs.
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 interacting with the MIB to
obtain information about network activity.
