Glossary SSH Stand-alone Mode Startup Configuration Subnet Subnet Mask Switch TCP/IP Telnet TFTP Trap Trunking UDP Unicast VLAN VSDL Secure Shell. Logs into a remote computer via a network, executes commands, and transfers files from one computer to another. Permits a device to operate independently from other devices. Retains the exact device configuration when the device is powered down or rebooted. Sub-network. Subnets are portions of a network that share a common address component. In TCP/IP networks, devices that share a prefix are part of the same subnet. For example, all devices with a prefix of 157.100.100.100 are part of the same subnet. Used to mask all or part of an IP address used in a subnet address. Filters and forwards packets between LAN segments. Switches support any packet protocol type. T Transmissions Control Protocol. Enables two hosts to communicate and exchange data streams. TCP guarantees packet delivery, and guarantees packets are transmitted and received in the order the are sent. Terminal Emulation Protocol. Enables system users to log in and use resources on remote networks. Trivial File Transfer Protocol. Uses User Data Protocol (UDP) without security features to transfer files. A message sent by the SNMP that indicates that system events have occurred. Link Aggregation. Optimizes port usage by linking a group of ports together to form a single trunk (aggregated groups). U User Data Protocol. Communication protocol that transmits packets but does not guarantee their delivery. A form a routing that transmits one packet to one user. V Virtual Local Area Networks. Logical subgroups that constitute a Local Area Network (LAN). This is done in software rather than defining a hardware solution. Very High Bit Rate DSL. An asymmetric DSL version used at the fiber optic junction point final drop to nearby customers. Glossary-12 www.hp.com Embedded Web System User Guide
