1. There are four trunks existing in this example Each has 400Mbps band width The top switch is configured to have four trunks and is cascaded to four lower switch units Z0 3 5 Virtual LAN VLAN Each port of the switch unit connects to one individual LAN segment There can be many Ethernet nodes located on each segment The switch performs network data forwarding between different LAN segments It al lows Ethernet nodes located on different segments to communicate with each other Basically all Ethernet nodes are in one single LAN A Virtual LAN VALN is a logical independent workgroup within a net work The member in this workgroup communicate as if they are sharing the same physical LAN segment VLANs are not limited by the hardware constraints that physically connect traditional LAN segments to a net work As a result VLANs can define a network into multiple logical configurations Because VLANs are self contained only the devices within the same VLAN can communicate with each other Ifa device in one VLAN wants to communicate with a device in another VLAN the traffic must go through a router This would enhance the security of the network In addition broadcasts from servers within each group would go to the members of its own VLAN This ensures that broadcasts cannot cause a network meltdown due to traffic volume Implementation The VLAN implementation of this switch allows2. 4 7 RTS 8 8 CTS 7 QR 9 5 5 Web Management Use any web browser with JAVA script support like Netscape Communi cator 4 x or Microsoft Internet Explorer 4 0 or later on any platform Con nect to the managed unit using the IP address as URL address http XXX XXX XXX XXX 5 6 Telnet Management Use Telnet software to perform the management operation The most convenient solution is using the built in Telnet function in a Windows 95 98 or NT PC Enter into DOS window and invoke telnet command gt tel net XXX XXX XXX XXX to connect to the managed switch The specified xxx xxx xxx xxx is the IP address of the managed switch 5 7 SNMP and RMON Management SNMP management and RMON activities are performed at a network management station running SNMP network management application manager software with graphical user interface The switch serves as an SNMP agent and provides RMON capabilities that allows network administrators to set parameters and view statistical counters defined in the MIB II Bridge MIB private MIB and RMON MIB The supported MIBs are available in the supplied CD ROM of the switch Use the SNMP management application software to compile the MIB file first before performing any management operation 5 8 Software Upgrade The device supports a Software Upgrade feature through TFTP protoco
