DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide To view the following window, click Management > Reboot Schedule Settings, as shown below: Figure 4-98 Reboot Schedule Settings Window The fields that can be configured are described below: Parameter Time Interval Time Date Save Before Reboot Description Select and enter the reboot schedule time interval value here. The reboot will be initiated after the specified time interval has passed. The range is from 1 to 43200 minutes (30 days). Select and enter the time at which the reboot should be initiated here. This time uses the 24-hour format, for example, 21:30. If the date was not specified, the reboot will be initiated when the system clock reaches the time specified within the next 24 hours. Select and enter the date at which the reboot should be initiated here. This date uses the following format: DD/MM/YYYY. For example, 23/12/2015. The reboot schedule can only be initiated within 30 days of configuration. Select this option to save all configuration changes made before the reboot is initiated. Click the Apply button to accept the changes made. Click the Delete button to remove the specified reboot schedule. NLB FDB Settings This window is used to display and configure the Network Load Balancing (NLB) FDB settings. The NLB function is used to support the Microsoft server load balancing application where multiple servers can share the same IP address and MAC address. The requests from clients will be forwarded to all the servers, but will only be processed by one of them. The server can work in two different modes: Unicast mode: The client uses a unicast MAC address as the destination MAC address to reach the server. Multicast mode: The client uses a multicast MAC address as the destination MAC address to reach the server. This destination MAC address is called the shared MAC address. However, the server uses its own MAC address (rather than the shared MAC address) as the source MAC address in the reply packet. In other words, a NLB unicast address is usually not the source MAC address of a packet. When the received packet contains a destination MAC address that matches the configured unicast MAC address, it will be forwarded to those configured ports, regardless of the VLAN membership configuration. Administrators cannot configure a static address of the MAC address table as a NLB address. However, if a MAC address is created as a NLB MAC address entry, the same MAC address can be still dynamically learnt in the Layer 2 MAC address table. In this situation, the NLB has higher priority; the dynamically learnt FDB entry won't take effect. 115
