set of layer 2 management features. It provides a variety of service features and multiple powerful
functions with high security.
The EIA-standardized framework and smart configuration capacity can provide flexible solutions
for a variable scale of networks. QoS and IGMP snooping/filtering optimize voice and video
application. Link aggregation increases aggregated bandwidth, optimizing the transport of
business critical data. SNMP, RMON, WEB/Telnet Log-in bring abundant management policies.
GES-2451 switch integrates multiple functions with excellent performance, and is friendly to
manage, which can fully meet the need of the users demanding higher networking performance.
2.2 Main Features
Resiliency and Availability
+ IEEE 802.1s Multiple Spanning Tree provides high link availability in multiple VLAN
environments.
+ Multicast snooping automatically prevents flooding of IP multicast traffic.
+ Root Guard protects root bridge from malicious attack or configuration mistakes
Layer 2 Switching
+ Supports up to 512 VLANs simultaneously (out of 4K VLAN IDs).
Quality of Service
+ Supports L2/L3 granular CoS with 4 priority queues per port.
+ Rate limiting confines the traffic flow accurately according to the preset value.
Manageability
+ Supports Telnet, SNMP v1/v2c/v3, RMON and web access.
+ Port Mirroring enables monitoring selected ingress/egress traffic.

21~24F shares the same LED with Port 21~24. The Port 21~24F and Port 21~24 are referred
to as “combo” ports, which means they cannot be used simultaneously, otherwise only SFP
ports work. The SFP module supports hot-plugging.
Note:
When using the SFP port with a 100M module or a gigabit module, you need to configure its
corresponding Speed and Duplex mode on Switching → Port → Port Config page. For 100M
module, please select 100MFD while select 1000MFD for gigabit module. By default, the Speed
and Duplex mode of SFP port is 1000MFD.
Reset: Press this button for five seconds or above to reset the software setting back to factory
