NOTICE: A NOTICE indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. CAUTION: A CAUTION indicates a potential for property damage, personal injury, or death. ___________________ Information in this document is subject to change without notice.

Admin Status -- Enables or disables traffic forwarding through the port. When Up is selected, the traffic is forwarded through the port. When Down is selected, no traffic is forwarded through the port. Current Port Status -- Specifies whether the port is currently operational or non-operational. Operational Status -- Indicates the port operational status. The possible field values are: Suspended -- Indicates that the port is currently active, and it is currently not transmitting or receiving traffic. Active -- Indicates that the port is currently receiving and transmitting traffic. Disable -- Indicates that the port is currently disabled and therefore, not receiving or transmitting traffic. Admin Speed -- The rate configured for the port. The port type determines what speed setting options are available. Admin Speed can only be designated when auto negotiation is disabled on the configured port. 47 Current Port Speed -- The actual synchronized port speed, in bits per second. Admin Duplex -- Full Duplex (FDX) indicates that the switch interface supports transmission between the device and another station, in both directions simultaneously. Half Duplex (HDX) indicates that the interface supports transmission between the device and the other station in one direction only at a time. Current Duplex Mode -- The synchronized port duplex mode of transmission. Auto Negotiation -- Enables Auto Negotiation on the port. This feature is a protocol between two link partners that enables a port to advertise its transmission rate, duplex mode and flow control capacity to its partner (Auto Negotiation has to be enabled on both communicating devices to operate). Current Auto Negotiation -- Specifies the current Auto Negotiating status. Admin Advertisement -- Designates the possible parameters of transmission: Max Capability, 10 Mbps at Half Duplex, 10 Mbps at Full Duplex, 100 Mbps at Half Duplex, 100 Mbps at Full Duplex, or 1000 Mbps at Full Duplex. Current Advertisement -- Specifies the current advertised port rate and mode of transmission. Backpressure -- The Backpressure mechanism makes it possible to avoid a temporary congestion and buffer overflow in the switch, by prohibiting transmission from an input device to the congested output device, when the number of packets in the output device exceeds a given threshold value. [. . . ] Router A Ethernet switch module that connects to separate networks. Routers forward packets between two or more networks. Routers operate at a Layer 3 level. S Server A central computer that provides services to other computers on a network. Services may include file storage and access to applications. [. . . ]
