LAN Discovery actively interrogates network devices to learn about attached hosts, servers, switches and routers. The discovered devices connected to the network are listed and additional details about each device are provided such as IP address, domain name, services provided, administrator, location, etc. Metrics provided include the IP address of the discovered hosts along with the network address, MAC address and SNMP information.
VLAN Scan detects and lists all the VLANs present on the IP network the test set is connected to. It can support the detection of nested VLANs on up to three layers. Results include the VLAN number, priority, and frame count. This tool is useful to discover configured VLANs on a port and bandwidth utilization per VLAN as well as providing the ability to detect VLAN configuration errors.
The Ping tool validates if there is IP connectivity to another IP-enabled device (host) by sending control message protocol (ICMP) echo request packets to the destination device and waiting for an ICMP response to validate the end-to-end connection. In addition, it also provides a round-trip time (latency) for packets sent by the local device to the destination far-end device. Other metrics include sent and lost packets.
The Traceroute test is a troubleshooting tool that discovers the path taken by IP packets across an IP network. It identifies the nodes or “hops” that the packet traversed on its way to the destination. The information provided by the tool includes the IP address of the nodes and the number of hops to that node and the total hops to reach the destination node. An example of how the traceroute tool can be used is to identify the routers along a data path to discover routing problems or to highlight firewall issues that may be blocking ICMP packets.
FTP Performance Test
FTP allows the transfer of files between a local PC and a remote FTP server. Using FTP, you can connect to an FTP server and transfer files in either direction by uploading a file to or downloading a file from an FTP server. File transfer involves two types of connections, a control connection and a data connection.
A typical use of the FTP Performance test tool is to measure the availability and response time of an FTP server. This test can be configured to upload a file to the server, download a file from the server or perform both tasks. The file is generated by the test and transferred to the specified location.
The HTTP Availability test measures the availability and response time of a hypertext transfer protocol (HTTP) server by downloading a web page. Results include the TCP connection time, the total page download time, the number of redirects and the redirect time.
