Highlight
IP Clustered Stacking Solution
With the design and implementation of SIP (Single IP Management), network administrators are allowed to
virtually stack up to 32 switches (GEL-1072/GTL-2880/GTP-2880/GTL-5280/GEP-2671/GEP-2672)
together and manage them as one logical unit through a single IP address regardless of geographical
locations of those switches. Comparing to traditional stacking, IP clustering eliminates the use of costly
cables and connectors. Furthermore, it minimizes the impact of any single point of failure.
LevelOne Easy Configuration Port (ECP) Technology
Each switch port can now be fully optimized through a predefined role and settings which are based on the
type of a device such as an IP camera or a VoIP phone to be connected to. For instance, even if a
surveillance system integrator who lacks of IT administration skills, can still easily enables the role and
applies settings like VLAN, QoS, port security and spanning tree to all connected IP cameras on a single
Web UI within a few minutes. Hence, simplifying network deployment and ensuring consistent
configurations across the network.
