D-Link Single IP Management Commands

Simply put, D-Link Single IP Management is a concept that will stack switches together over
Ethernet instead of using stacking ports or modules. 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. 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).
•
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 32 switches (numbered 0-31), 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 default VLAN on any
•
switch.
SIM allows intermediate devices that do not support SIM. This enables the user to manage a
•
switch 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 DES 3800 Series may take
on three different roles:
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.
•
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 IP group.
•
It is connected to the CS through the CS management VLAN.
•
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 through an automatic function of the DES-
3828, or 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:
It is not a CS or MS of another Single IP group.
