DES-3200-10/18/28/28F Layer 2 Ethernet Managed Switch User Manual
Time Range Settings
This window is used in conjunction with the Access Profile feature to determine a starting point and an ending point,
based on days of the week, when an Access Profile configuration will be enabled on the Switch. Once configured here,
the time range settings are to be applied to an access profile rule using the Access Profile table. The user may enter
up to 64 time range entries on the Switch.
To open this window, click Configuration > Time Range Settings:

Single IP Management
Simply put, D-Link Single IP Management 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:
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 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 system 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.
