DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide To view the following window, click Management > Stacking > Stacking Bandwidth, as shown below: Figure 4-87 Stacking Bandwidth Window The fields that can be configured are described below: Parameter Stack Bandwidth Description Select the stacking bandwidth here. Option to choose from are: • 2-Port - Specifies 2 Switch ports to be used for stacking. • 4-Port - Specifies 4 Switch ports to be used for stacking. Click the Apply button to accept the changes made. Virtual Stacking (SIM) D-Link Single IP Management (SIM) is a concept that will stack Switches together over Ethernet instead of using stacking ports or modules. There are some advantages in implementing the Single IP Management feature: • SIM can simplify management of small workgroups or wiring closets while scaling the network to handle increased bandwidth demand. • SIM can reduce the number of IP address needed in your network. • SIM can eliminate any specialized cables for stacking connectivity and remove the distance barriers that typically limit your topology options when using other stacking technology. Switches using D-Link Single IP Management (labeled here as SIM) must conform to the following rules: • SIM is an optional feature on the Switch and can easily be enabled or disabled through the Command Line Interface or Web Interface. SIM grouping has no effect on the normal operation of the Switch in the network. • There are three classifications for Switches using SIM. The Commander Switch (CS), which is the master Switch of the group, Member Switch (MS), which is a Switch that is recognized by the CS a member of a SIM group, and a Candidate Switch (CaS), which is a Switch that has a physical link to the SIM group but has not been recognized by the CS as a member of the SIM group. • A SIM group can only have one Commander Switch (CS). • A SIM group accepts up to 32 Switches (numbered 1-32), not including the Commander Switch (numbered 0). • Members of a SIM group must be in the same Layer 2 network. • There is no limit to the number of SIM groups in the same IP subnet (broadcast domain); however a single Switch can only belong to one group. • If multiple VLANs are configured, the SIM group will only utilize the management VLAN on any Switch. • SIM allows intermediate devices that do not support SIM. This enables the user to manage Switches that are more than one hop away from the CS. 114
