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 33 switches
(numbered 0-32), 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 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 DGS-3600 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:
o
It has an IP Address.
o
It is not a Commander Switch or Member Switch of another Single IP group.
o
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:
o
It is not a CS or MS of another IP group.
o
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 DGS-3600, 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:
o
It is not a CS or MS of another Single IP group.
o
It is connected to the CS through the CS management VLAN.
The following rules also apply to the above roles:
1.
Each device begins in the Candidate state.
2.
CS’s must change their role to CaS and then to MS, to become a MS of a SIM group. Thus the CS cannot
directly be converted to a MS.
3.
The user can manually configure a CS to become a CaS.
4.
A MS can become a CaS by:
a.
Being configured as a CaS through the CS.
b.
If report packets from the CS to the MS time out.
5.
The user can manually configure a CaS to become a CS
