VLAN Inoformation · VLAN ID ­ A number in the range 1 - 4094 which identifies the VLAN. · VLAN Member ­ A list of the ports that are members of the VLAN. By default, all ports are members of VLAN 1. 10 WEB CONFIGURATION Web ­ Click STATUS, Overview. Figure 3 Switch Information 11 CONFIGURING THE SWITCH Showing Port Statistics You can display statistics on network traffic from the ports. These statistics can be used to identify potential problems with the switch (such as a faulty port or unusually heavy loading). All values displayed have been accumulated since the last system reboot, but can be reset to zero by clicking the CLEAR button. The current statistics are not displayed until you click the REFRESH button. Table 4 Port Statistics Parameter Interface Statistics Received Octets Received Unicast Packets Received Errors The total number of octets received on the interface, including framing characters. The number of subnetwork-unicast packets delivered to a higher-layer protocol. The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. The total number of packets that higher-level protocols requested be transmitted, and which were addressed to a multicast address at this sub-layer, including those that were discarded or not sent. The total number of packets that higher-level protocols requested be transmitted, and which were addressed to a broadcast address at this sub-layer, including those that were discarded or not sent. The total number of received packets that set as High Priority in the QoS settings. Description Transmitted Multicast Packets Transmitted Broadcast Packets Received High Priority Packets Transmitted High Priority The total number of transmitted packets that set as Packets High Priority in the QoS settings. Received Multicast Packets The number of packets, delivered by this sub-layer to a higher (sub-)layer, which were addressed to a multicast address at this sub-layer. 12 WEB CONFIGURATION Table 4 Port Statistics (Continued) Parameter Received Broadcast Packets Transmitted Octets Transmitted Unicast Packets Description The number of packets, delivered by this sub-layer to a higher (sub-)layer, which were addressed to a broadcast address at this sub-layer. The total number of octets transmitted out of the interface, including framing characters. The total number of packets that higher-level protocols requested be transmitted to a subnetwork-unicast address, including those that were discarded or not sent. The number of outbound packets that could not be transmitted because of errors. The total number of received packets that set as High Priority in the QoS settings. The total number of transmitted packets that set as High Priority in the QoS settings. The total number of events in which packets were dropped due to lack of resources. The total number of frames (bad, broadcast and multicast) received. [. . . ] Possible Solutions · Check for loose connections. · Check the power outlet by using it for another device. Symptom Link LED does not light after connection is made. Probable Causes · Switch port, network card or cable may be defective. [. . . ]
