xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch
Single IP vs. Switch Stacking
Single IP and Switch Stacking are two different entities and should not be equated by users. Within a switch stack, all functions
are shared among switches in the stack and this switch stack is treated as one switch. Layer 2 and Layer 3 features, such as VLAN
configurations and packet routing can be configured across switches in the stack. For example, mirroring functions can be shared
within the stack, so a mirror target port may be on one switch in the stack and the source ports may be on another.
For Single IP Management, switches are separate entities that share a common IP address. Therefore, Layer 2 and Layer 3
functions CANNOT be shared among switches in the Single IP group. The purpose of the Single IP Management function is to
share firmware and configuration files among switches within the Single IP Group. To have similar configurations on switches
within the Single IP Group, users can upload identical configuration files to the Single IP Group using the
Configuration File
Backup/Restore window located under the the Single IP heading on the switch, and described later in this section. Once this file
is entered and uploaded to switches within the group, most configurations should be the same for the switches in the Single IP
Group.
SIM Using the Web Interface
All xStack DGS-3400 Series 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 Settings
folder and click the SIM Settings link, revealing the following window.

Change the SIM State to Enabled using the pull down menu and click Apply . The screen will then refresh and the SIM Settings
window will look like this:

Parameter Description
SIM State Use the pull-down menu to either enable or disable the SIM state on the Switch. Disabled will
render all SIM functions on the Switch inoperable.
Role State Use the pull-down menu to change the SIM role of the Switch. The two choices are:
Candidate - A Candidate Switch (CaS) is not the member of a SIM group but is connected to a
Commander Switch. This is the default setting for the SIM role of the DGS-3400 Series.
Commander - Choosing this parameter will make the Switch a Commander Switch (CS). The
user may join other switches to this Switch, over Ethernet, to be part of its SIM group.
Choosing this option will also enable the Switch to be configured for SIM.
Discovery Interval The user may set the discovery protocol interval, in seconds that the Switch will send out
discovery packets. Returning information to a Commander Switch will include information
about other switches connected to it. (Ex. MS, CaS). The user may set the Discovery Interval
from
30 to 90 seconds.
