Maximum Cell Transfer Delay: In an ATM network, the total of
the maximum cell delay variation and the fixed delay across the link or node.
MCTD is one of four link metrics that are exchanged using PNNI topology
state packets to verify the available resources of an ATM network. There is
one MCTD value assigned to each traffic class. See also: MCDV.
See: routing metric.
Management Information Base: Used with SNMP management soft-
ware to gather information from remote devices. The management station
can poll the remote device for information, or the MIB running on the
remote station can be programmed to send information on a regular basis.
Term used to describe LAN segmentation using
Layer 2 switching.
Multichannel Interface Processor: The resident interface processor on
Cisco 7000 series routers, providing up to two channelized T1 or E1 con-
nections by serial cables connected to a CSU. The two controllers are capable
of providing 24 T1 or 30 E1 channel groups, with each group being intro-
duced to the system as a serial interface that can be configured individually.
millions of instructions per second: A measure of processor speed.
Multilink PPP: A technique used to split, recombine, and sequence
datagrams across numerous logical data links.
Multi-Layer Switching: Switching normally takes place at Layer 2.
When Layer 3 information is allowed to be cached, Layer 2 devices have the
capability of rewriting and forwarding frames based on the Layer 3
Multilayer Switching Protocol: A protocol that runs on the router
and allows it to communicate to the MLS-SE regarding topology or security
Multilayer Switching Route Processor: An MLS-capable router or
an RSM (Route Switch Module) installed in the switch. See also: RSM and
Multilayer Switching Switching Engine: An MLS-capable switch
(a 5000 with an NFFC or a 6000 with an MSFC and PFC). See also: MLS,
NFFC, MSFC and PFC.
