[. . . ] After returning to Normal mode, the packet flow will be increased by 25%. The switch will then return to its interval checking and dynamically adjust the packet flow to avoid overload of the Switch. NOTICE: When Safeguard Engine is enabled, the Switch will allot bandwidth to various traffic flows (ARP, IP) using the FFP (Fast Filter Processor) metering table to control the CPU utilization and limit traffic. To enable Safeguard Engine or configure advanced Safeguard Engine settings for the Switch, click Security > Safeguard Engine, which will open the following window. Figure 9- 2. Safeguard Engine window To enable the Safeguard Engine option, click the Enabled radio button next to Safeguard Engine State at the top of the window. To configure the advanced settings for the Safeguard Engine, set the following parameters and click Apply. 114 DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch Parameter Safeguard Engine State Rising Threshold (20% - 100%) Falling Threshold (20% - 100%) Trap / Log Mode Description Use the radio button to globally enable or disable Safeguard Engine settings for the Switch. Used to configure the acceptable level of CPU utilization before the Safeguard Engine mechanism is enabled. Once the CPU utilization reaches this percentage level, the Switch will move into Exhausted mode, based on the parameters provided in this window. Used to configure the acceptable level of CPU utilization as a percentage, where the Switch leaves the Safeguard Engine state and returns to normal mode. Use the pull-down menu to enable or disable the sending of messages to the device's SNMP agent and switch log once the Safeguard Engine has been activated by a high CPU utilization rate. Used to select the type of Safeguard Engine to be activated by the Switch when the CPU utilization reaches a high rate. The user may select: Fuzzy ­ If selected, this function will instruct the Switch to minimize the IP and ARP traffic flow to the CPU by dynamically allotting an even bandwidth to all traffic flows. Strict ­ If selected, this function will stop accepting all ARP packets not intended for the Switch, and will stop receiving all unnecessary broadcast IP packets, until the storm has subsided. The default setting is Fuzzy mode. Trusted Host Up to ten trusted host secure IP addresses may be configured and used for remote Switch management. It should be noted that if one or more trusted hosts are enabled, the Switch will immediately accept remote instructions from only the specified IP address or addresses. If you enable this feature, be sure to first enter the IP address of the station you are currently using. To create a list of trusted IP addresses that can access the Switch, click Security > Trusted Host, which will open the following window. Figure 9- 3. Trusted Host window To configure secure IP addresses for trusted host management of the Switch, type the IP address and the net mask of the station you are currently using in the two fields, as well as up to nine additional IP addresses of trusted hosts, one by one. Click the Apply button to assign trusted host status to the IP addresses. This goes into effect immediately. 115 DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch IP-MAC-Port Binding The IP network layer uses a four-byte address. Binding these two address types together allows the transmission of data between the layers. The primary purpose of IP-MAC binding is to restrict the access to a switch to a number of authorized users. [. . . ] Kunder kan kontakte D-Links teknisk support via våre hjemmesider, eller på tlf.
