Sim Using The Web Interface - D-Link DES-3526 Manual

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 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 through an
automatic function of the DES-3526, 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.
•
It is connected to the CS through the CS management VLAN
•
The following rules also apply to the above roles:
Each device begins in a Commander state.
•
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.
The user can manually configure a CS to become a CaS.
•
A MS can become a CaS by:
Being configured as a CaS through the CS.
•
If report packets from the CS to the MS time out.
•
The user can manually configure a CaS to become a CS
•
The CaS can be configured through the CS to become a MS.
•
After configuring one switch to operate as the CS of a SIM group, additional DES-3526 switches may
join the group either by an automatic method or by manually configuring the Switch to be a MS. The
CS will then serve as the in band entry point for access to the MS. The CS's IP address will become
the path to all MS's of the group and the CS's Administrator's password, and/or authentication will
control access to all MS's of the SIM group.
With SIM enabled, the applications in the CS will redirect the packet instead of executing the packets.
The applications will decode the packet from the administrator, modify some data, and then send it to
the MS. After execution, the CS may receive a response packet from the MS, which it will encode and
send it back to the administrator.
When a CS becomes a MS, it automatically becomes a member of the first SNMP community (include
read/write and read only) to which the CS belongs. However, if a MS has its own IP address, it can
belong to SNMP communities to which other switches in the group, including the CS, do not belong.

SIM Using The Web Interface

All DES-3526 switches are set as Candidate (CaS) switches, as their factory default configuration and
Single IP Management will be disabled. To enable SIM for the Switch using the Web interface, go to
the Single IP Management folder and click the SIM Settings link, revealing the following window.
