ITU-T Y.1564 is designed to serve as a network service level agreement (SLA) validation tool, ensuring that a service meets its guaranteed performance settings in a controlled test time, to ensure that all services carried by the network meet their SLA objectives at their maximum committed rate, and to perform medium- and long-term service testing, confirming that network elements can properly ...
Loop around is a method of testing between stations that are not necessarily adjacent, wherein two lines are used, with the test being done at one station and the two lines are interconnected at the distant station. A patch cable may also function as loopback, when applied manually or automatically, remotely or locally, facilitating a loop-back ...
Ethernet Configuration Testing Protocol is a diagnostic protocol included in the Xerox Ethernet II specification. [1] Functionality of the protocol is similar to that offered by ping but it operates at the data link layer as opposed to the network layer. Ethernet Configuration Testing Protocol was implemented on DEC hosts and Cisco routers. [2]
The ARCNET Sniffer developed as an internal test tool by Zynar used the IBM PC ARCNET Network Interface Card developed by Nestar for the PLAN networking systems. That board used the COM9026 integrated ARCNET controller from Standard Microsystems Corporation , which had been developed in collaboration with Datapoint.
IEEE 802.1ag is an amendment to the IEEE 802.1Q networking standard which introduces Connectivity Fault Management (CFM).This defines protocols and practices for the operations, administration, and maintenance (OAM) of paths through 802.1 bridges and local area networks (LANs).
Some vendors define TAP as an acronym for test access point or terminal access point; however, those are backronyms. The monitored traffic is sometimes referred to as the pass-through traffic, while the ports that are used for monitoring are the monitor ports. There may also be an aggregation port for full-duplex traffic, wherein the A traffic ...
All ports have the same link speed and run in full duplex mode. Now, when a broadcast frame enters the switch through port A, this frame is forwarded to all ports but the source port, i.e. ports B and C. Both frames exiting ports B and C traverse the loop in opposite directions and reenter the switch through their counterpart port.
Forgot to connect the loopback cables when testing a UUT with any networking interface (Ethernet/optical/etc ports). This will cause the traffic test to fail. Skipped some test process. Some test process will configure the UUT to load some firmware or put it in some state (i.e. preparing it to run in burn-in mode) so when the test automation ...
