notication
Redundant Ring, Fast Recovery for Critical Network Applications
The GS-4210-48T4S supports redundant ring technology and features strong,
rapid self-recovery capability to prevent interruptions and external intrusions.
It incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection
Switching) technology, Spanning Tree Protocol (802.1s MSTP) into customer’s
network to enhance system reliability and uptime in various environments.
IPv6/IPv4 Dual Stack Management
Supporting both IPv6 and IPv4 protocols, the GS-4210-48T4S helps the SMBs to
step in the IPv6 era with the lowest investment as its network facilities need not be
replaced or overhauled if the IPv6 FTTx edge network is set up.
Robust Layer 2 Features
The GS-4210-48T4S can be programmed for advanced switch management
functions such as dynamic port link aggregation, 802.1Q VLAN and Q-in-Q
VLAN, Multiple Spanning Tree Protocol (MSTP), loop and BPDU guard, IGMP
snooping, and MLD snooping. Via the link aggregation, the GS-4210-48T4S
allows the operation of a high-speed trunk to combine with multiple ports such as
a 16Gbps fat pipe, and supports fail-over as well. Also, the Link Layer Discovery
Protocol (LLDP) is the Layer 2 protocol included to help discover basic information
about neighboring devices on the local broadcast domain.
