used to access network services.

MS-CHAP
Microsoft CHAP.
MTU
maximum transmission unit. The maximum number of bytes in a packet that can flow efficiently
across the network with best response time. For Ethernet, the default MTU is 1500 bytes, but each
network can have different values, with serial connections having the smallest values. The MTU is
described in RFC 1191.
multicast
Refers to a network addressing method in which the source transmits a packet to multiple destinations,
a multicast group, simultaneously. See also PIM, SMR.
N
N2H2
A third-party, policy-oriented filtering application that works with the ASA to control user web
access. N2H2 can filter
username, and password. The N2H2 corporation was acquired by Secure Computing in October, 2003.
NAT
Network Address Translation. Mechanism for reducing the need for globally unique IP addresses.
NAT allows an organization with addresses that are not globally unique to connect to the
translating those addresses into a globally routable address space.

NetBIOS
Network Basic Input/Output System. A Microsoft protocol that supports Windows hostname
registration, session management, and data transfer. The ASA supports NetBIOS by performing
of the packets for NBNS UDP port 137 and NBDS UDP port 138.
netmask
See mask.
network
In the context of ASA configuration, a network is a group of computing devices that share part of an
IP address space and not a single host. A network consists of multiple nodes or hosts. See also host,
Internet, intranet, IP, LAN, and node.
NMS
network management system. System responsible for managing at least part of a network. An NMS is
generally a reasonably powerful and well-equipped computer, such as an engineering workstation.
NMSs communicate with agents to help keep track of network statistics and resources.
