Cisco IOS Release: Multiple releases
SNMP—Simple Network Management Protocol. A network management protocol used almost
exclusively in TCP/IP networks. SNMP provides a means to monitor and control network devices,
manage configurations, collect statistics, monitor performance, and ensure network security.

tailend—The downstream, receive end of a tunnel.
traffic engineering—Techniques and processes that cause routed traffic to travel through the network
on a path other than the one that would have been chosen if standard routing methods were used.

trap (see notification)—A message sent by an SNMP agent to a network management station, console,
or terminal to indicate that a significant event within Cisco IOS software has occurred. Traps
(notifications) are less reliable than inform requests, because the receiver of the trap does not send an
acknowledgment of receipt; furthermore, the sender of the trap cannot determine if the trap was received.

VCI—virtual channel identifier. A 16-bit field in the header of an ATM cell. The VCI, together with the
VPI, is used to identify the next network VCL as the cell passes through a series of ATM switches on its
way to its final destination.

VCC—virtual channel connection. A VCC is a logical circuit consisting of VCLs that carries data
between two endpoints in an ATM network. Sometimes called a virtual circuit connection.

VCL—virtual channel link. A VCL is the logical connection that exists between two adjacent switches
in an ATM network.

VPI—virtual path identifier. An 8-bit field in the header of an ATM cell. The VPI, together with the VCI,
is used to identify the next network VCL (see above) as the cell passes through a series of ATM switches
on its way to its final destination.
