Single Ip Vs. Switch Stacking; Sim Settings - D-Link xStack DGS-3400 Series Reference Manual

x Stack
NOTE: SIM Management does not support IPv6. For users wishing to utilize this function,
switches in the SIM group must be configured with IPv4 addresses. IPv6 for SIM management
will be supported in a future release of this 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 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.
