selected bridge interfaces.
Stack
A layered set of protocols which work together to provide a set of network
functions. Each intermediate layer uses the layer below it to provide a service to the
layer above.
Standalone Mode
An option to separate a module from the other modules in a device so that its bus is
independent. This may be desirable, for example, if one module has exceptionally
heavy traffic that might affect other modules.
Subnet
Short for subnetwork. A subnet is a portion of a network that shares a common
address component. On TCP/IP networks, a subnet includes all devices whose IP
addresses have the same prefix. For example, all devices with IP addresses that start
with 133.100.100 are part of the same subnet.
Subnet Mask
A 32-bit address mask used in IP to indicate the bits of an IP address that are being
used for the subnet address.
Switch
A device that filters and forwards packets between LAN segments. Switches
operate at the Data Link Layer of the OSI reference model and support any packet
protocol.
Switch Monitoring
Refer to SMON on page 253.
TCP/IP
Transmission Control Protocol/Internet Protocol. Common name for the suite of
protocols used to connect hosts on the Internet. TCP/IP uses several protocols, of
which TCP and IP are the main ones.
Telnet
A terminal emulation protocol for TCP/IP networks. Telnet is used for remote
terminal connection, enabling users to log in to remote systems and use these
resources as if they were connected to a local system.
TFTP
Trivial File Transfer Protocol. A simple form of File Transfer Protocol, using User
Datagram Protocol (UDP) and providing no security features. TFTP is often used by
servers to boot diskless workstations, X-terminals, and routers.
