Single IP Management Settings

Single IP Management (SIM) Overview
D-Link Single IP Management is a concept that stacks switches together over Ethernet instead of using stacking ports or modules.
There are some advantages in implementing the "Single IP Management" feature:
1. SIM can simplify management of small workgroups or wiring closets while scaling the network to handle increased
bandwidth demand.
2. SIM can reduce the number of IP address needed in your network.
3. 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 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).
All switches in a particular SIM group must be in the same IP subnet (broadcast domain). Members of a SIM group
cannot cross a router.
A SIM group accepts up to 33 switches (numbered 1-32), including the Commander Switch (numbered 0).
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. SIM switches 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:
It has an IP Address.
It is not a commander switch or member switch of another Single IP group.
It is connected to the member switches through its management VLAN.
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:
It is not a CS or MS of another Single IP group.
It is connected to the CS through the CS management VLAN.
3. Candidate Switch (CaS) - This is a switch that is ready to join a SIM group but is not yet a member of the SIM group.
The Candidate Switch may join the SIM group of a switch by manually configuring it to be a MS of a SIM group. A
switch configured as a CaS is not a member of a SIM group and will take on the following characteristics:

Choose the beginning and ending range of ports to be configured for counter polling.
Enter the previously configured Analyzer Server ID to state the device that will be receiving
datagrams from the Switch. These datagrams will include the counter poller information taken
using the polling mechanism configured here.
Users may configure the Polling Interval here. The switch will take a poll of the IF counters
every time this interval reaches 0, and this information will be included in the sFlow datagrams
that will be sent to the sFlow Analyzer for examination. Ticking the Disabled check box will
disable the counter polling for this entry.
