If a user does not save the result into NVRAM with the Save Changes function, the switch will recover all the settings the last user configured after the switch is rebooted. Figure 5-42. Factory Reset window Save Changes The DES-3226L has two levels of memory, normal RAM and non-volatile or NV-RAM. To retain any configuration changes permanently, highlight Save Changes on the Basic Setup menu. The following windows will appear to verify that your new settings have been saved to NV-RAM. 57 DES-3226L Layer 2 Fast Ethernet Switch User's Guide Figure 5-43.

Figure 6-2. STP Switch Settings window The Switch supports 801. 2d Spanning Tree Protocol, which allows you to create alternative paths (with multiple switches or other types of bridges) in your network. Click Apply after making changes to the window above. 60 DES-3226L Layer 2 Fast Ethernet Switch User's Guide Parameters that you can change are: Parameter Status Description This drop-down menu allows you to enable the Spanning Tree Protocol setting. <20> ­ The Maximum Age can be from 6 to 40 seconds. At the end of the Maximum 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. <2> ­ The Hello Time can be 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. <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. <32768> ­ A Bridge Priority can be from 0 to 61, 440. [. . . ] If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · · · · Reorient or relocate the receiving antenna.
