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 user's 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 cannot cross a router.
•
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.
The SIM group is a group of switches that are managed as a single entity. The Switch may take on three
different roles:
1. Commander Switch (CS) - This is a switch that has been manually configured as the controlling
device for a group, and takes on the following characteristics:



2. Member Switch (MS) - This is a switch that has joined a single IP group and is accessible from the
CS, and it takes on the following characteristics:

Description
Select the unit ID of the switch in the stack.
Select the new box ID for the switch that is selected in the Current
Unit ID. The user may choose any number between 1 and 4 to identify
the switch in the switch stack. Auto will automatically assign a box
number to the switch in the switch stack.
Enter the priority of the switch stacking unit. The range is from 1 to 63.
It has an IP Address.
It is not a command switch or member switch of another Single IP group.
It is connected to the member switches through its management VLAN.
It is not a CS or MS of another IP group.
