Switches operate on the data link layer of the Open Systems Interconnection (OSI) reference model.Synchronous forces the bit stream to be consistent in timing. In effect, one device tries to use the same rate as the device on the other end of the serial link. However, by checking for changes in voltage states across the link, the device can notice small changes in rate at each endpoint and adjust its own rate accordingly.The syslog syslog server receives system messages from network devices and saves these messages in a database. Syslog servers also provide the ability to report these system messages. Some servers are even able to select system messages in response to certain actions (such as e-mail and paging).T1 This is a line pulled from the telephone company that allows data to be transferred at 1.544Mbit/s and can be treated as 24 separate 64Kbit/s DS0 channels (with an additional 8Kbit/s overhead bandwidth).T3 This is a line pulled from the telephone company that allows data to be transmitted at 44.736Mbit/s and can be thought of as the sum of 28 separate 1.544Mbit/sDSl (T1) channels and overhead bandwidth.A common abbreviation used by telco telephone companies. Trivial File Transfer Protocol (TFTP) An application layer protocol that allows files to be transferred from one computer to another over a network, but with fewer features and therefore less storage space required by the software.Topology Database ) A structured data that describes the topology of a network to a routing protocol. Link state and balanced hybrid routing protocols use topology tables from which to create entries in the routing table.traceroute A program provided by many systems for tracing packets to their destination path. It is primarily used to debug routing problems between two hosts.trap In SNMP, trap is a message type. This message is automatically generated by the management device. The message is based on a threshold value set by the network administrator.
