[. . . ] DGS-3224TG Managed 24-Port Gigabit Ethernet Switch User's Guide First Edition (October 2004) 651TG3224015 Printed In Taiwan RECYCLABLE Wichtige Sicherheitshinweise 1. Um eine Beschädigung des Gerätes zu vermeiden sollten Sie nur Zubehörteile verwenden, die vom Hersteller zugelassen sind. Verwenden Sie nur sichere Standorte und beachten Sie die Aufstellhinweise des Herstellers. Die Belüftungsöffnungen dienen zur Luftzirkulation die das Gerät vor Überhitzung schützt. [. . . ] Therefore, it is advisable to keep the default settings as set at the factory unless it is absolutely necessary to change them. The user-changeable parameters in the Switch are as follows: · · Status:<Disabled> ­ Toggle to Enabled to implement the Spanning Tree Protocol on the switch. At the end of the Max Age, if a BPDU has still not been received from the Root Bridge, your switch will start sending its own BPDU to all other switches for permission to become the Root Bridge. If it turns out that your switch has the lowest Bridge Identifier, it will become the Root Bridge. Hello Time: [2 ] ­ The Hello Time can be set from 1 to 10 seconds. This is the interval between two transmissions of BPDU packets sent by the Root Bridge to tell all other switches that it is indeed the Root Bridge. If you set a Hello Time for your switch, and it is not the Root Bridge, the set Hello Time will be used if and when your switch becomes the Root Bridge. · Forward Delay: [15] ­ The Forward Delay can be from 4 to 30 seconds. This is the time any port on the switch spends in the listening state while moving from the blocking state to the forwarding state. Priority: [32768] ­ A Priority for the switch can be set from 0 to 65535. This number is used in the voting process between switches on the network to determine which switch will be the root switch. A low number indicates a high priority, and a high probability that this switch will be elected as the root switch. 45 · · DGS-3224TG Gigabit Ethernet Switch User's Guide Note: Observe the following formulas when setting the above parameters: Max. Age 2 x (Hello Time + 1 second) Port Spanning Tree Settings In addition to setting Spanning Tree parameters for use on the switch level, the DGS-3224TG allows for the configuration of Spanning Tree Protocol on individual ports. To define individual ports, highlight Port Settings on the Configure Spanning Tree menu above and press Enter. Figure 6-17. Port Spanning Tree Settings screen Toggle the View Ports field to the range of ports to be configured. Enter the port number or port range in the Configure Port from [ ] to [ ] field. After enabling or disabling STP Status, you can set the spanning tree port cost and priority. Configure Static (Destination-Address Forwarding) Table The Configure Static (Destination-Address Forwarding) Table menu allows you to access screens to create, modify, and delete both Static Unicast Forwarding Table and Static Multicast Forwarding Table entries, respectively. Highlight Configure Static (Destination-Address Forwarding) Table on the Configuration menu and press Enter: 46 DGS-3224TG Gigabit Ethernet Switch User's Guide Figure 6-18. Configure Static (Destination-Address Forwarding) Table menu Setup Unicast Forwarding Table Highlight Configure Static Forwarding Table on the menu above to access the following screen: Figure 6-19. Setup Unicast Forwarding Table screen The Action field can be toggled between Add/Modify and Delete using the space bar. Enter the VID in the VLAN ID field and the MAC address to be statically entered in the forwarding table in the MAC 47 DGS-3224TG Gigabit Ethernet Switch User's Guide Address field. There are two static unicast forwarding types to select from, Permanent and DeleteOnReset.
