User manual ACER LC-WV20

[. . . ] Getting Started: A startup guide for basic switch installation and settings. Terms/Usage In this guide, the term “Switch” (first letter capitalized) refers to the Smart Switch, and “switch” (first letter lower case) refers to other Ethernet switches. Some technologies refer to terms “switch”, “bridge” and “switching hubs” interchangeably, and both are commonly accepted for Ethernet switches. A NOTE indicates important information that helps a better use of the device. [. . . ] Below are the pre-defined voice traffic’s OUI: OUI 00:E0:BB 00:03:6B 00:E0:75 00:D0:1E 00:01:E3 00:60:B9 00:0F:E2 00:09:6E Vendor 3Com Cisco Veritel Pingtel Siemens NEC/ Philips Huawei-3COM Avaya Mnemonic Name 3com cisco veritel pingtel siemens nec&philips huawei&3com avaya Default OUI: Pre-defined OUI values, including brand names of 3COM, Cisco, Veritel, Pingtel, Siemens, NEC/Philips, Huawei3COM, and Avaya. User defined OUI: You can manually create a Telephony OUI with a description. The maximum number of user defined OUIs is 10. It will occupy one ACL rule when selecting a user defined OUI by default, and to configure one user-defined OUI will take extra one ACL rule. System will auto generate an ACL profile (Profile ID: 51) for all the Voice VLAN rules. 36 5 Configuration D-Link Web Smart Switch User Manual Select the OUI and press Add to the lower table to complete the Auto Voice VLAN setting. Configuration > Link Aggregation > Port Trunking The Trunking function enables the combining of two or more ports together to increase bandwidth. Up to eight Trunk groups may be created, and each group consists up to eight ports. Select the ports to be grouped together, and then click Apply to activate the selected Trunking groups. Two types of link aggregation can be selected: Static - Static link aggregation. Figure 63 – Configuration > Link Aggregation > Port Trunking NOTE: Each combined trunk port must be connected to devices within the same VLAN group. If a subnet is expected to be lossy, the Robustness Variable may need to be increased. The Robustness Variable cannot be set to zero, and it SHOULD NOT be. Query Interval (60-600 sec): The Query Interval is the interval between General Queries sent. By adjusting the Query Interval, the number of IGMP messages can be increased or decreased; larger values will cause IGMP Queries to be sent less often. Router Timeout (60-600 sec): This is the interval after which a learned router port entry will be purged. For each router port learned, a 'Router Port Purge Timer' runs for 'Router Port Purge Interval'. This timer will be restarted whenever a Query control message is received over that port. If there are no Query control messages received for 'Router Port Purge Interval' time, the learned router port entry will be purged. 38 5 Configuration D-Link Web Smart Switch User Manual Last Member Query Interval (1-25 sec): The Last Member Query Interval is the Max Response Time inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of time between Group-Specific Query messages. This value may be adjusted to modify the "leave latency" of the network. A reduced value results in reduced time to detect the loss of the last member of a group. [. . . ] This will outfit your network with a powerful 1000-Mbps-capable backbone/server connection. Fast Ethernet Technology The growing importance of LANs, and the increasing complexity of desktop computing applications, are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. [. . . ]
