Powerful 10Gbps and Layer 3 Routing Solution for Enterprise Backbone and Data Center Networking
PLANET GS-6311-24T4X is a brand-new Layer 3 Managed Gigabit Switch with 10Gbps uplink capability for various kinds of network applications and flexible deployment. The GS-6311-24T4X features 24 10/100/1000BASE-T RJ45 copper ports and 4 1G/10GBASE-X SFP+ ports with 128Gbps switch fabric delivered in a 1U rugged case with fanless design.

The GS-6311-24T4X provides high-density performance, Layer 3 static routing, RIP (Routing Information Protocol) and OSPF (Open Shortest Path First). With 10Gbps interfaces and 128Gbps switching fabric, the GS-6311-24T4X can handle extremely large amounts of data in a secure topology linking to an enterprise backbone or high-capacity servers. The powerful multicast routing and network security features make the GS-6311-24T4X perform effective data traffic control for ISP and enterprise VoIP, video streaming, and multicast applications. 

High Performance 10Gbps Ethernet Capacity
The four SFP+ ports built in the GS-6311-24T4X boasts a high-performance switch architecture that is capable of providing non-blocking switch fabric and wire-speed throughput as high as up to 128Gbps, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands. Each of the SFP+ ports supports Dual-Speed, 10GBASE-SR/LR or 1000BASE-SX/LX, meaning the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently.

Redundant Ring, Fast Recovery for Critical Network Applications
The GS-6311-24T4X 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 and Spanning Tree Protocol (802.1s MSTP) into customer’s network to enhance system reliability and uptime in harsh environments. In a certain simple Ring network, the recovery time could be less than 50ms to quickly bring the network back to normal operation. 

Layer 3 Routing Support
The GS-6311-24T4X enables the administrator to conveniently boost network efficiency by configuring Layer 3 static routing manually, the RIP (Routing Information Protocol) or OSPF (Open Shortest Path First) settings automatically. 

The RIP can employ the hop count as a routing metric and prevent routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. 
The OSPF is an interior dynamic routing protocol for autonomous system based on link state. The protocol creates a database for link state by exchanging link states among Layer 3 switches, and then uses the Shortest Path First algorithm to generate a route table based on that database.

Strong Multicast
The GS-6311-24T4X supports abundant multicast features. In Layer 2, it features IPv4 IGMPv1/v2/v3 snooping and IPv6 MLD v1/v2 snooping. In Layer 3 multicast protocols, it features IGMPv1/v2/v3. With Multicast VLAN Register (MVR), multicast receiver/sender control and illegal multicast source detect functions which make the GS-6311-24T4X great for any robust networking.

Full IPv6 Support
The GS-6311-24T4X provides IPv6 management and enterprise-level secure features such as SSH, ACL, WRR and RADIUS authentication. It thus helps the enterprises to step in the IPv6 era with the lowest investment. In addition, you don’t need to replace the network facilities when the IPv6 FTTx edge network is built.

Robust Layer 2 Features
The GS-6311-24T4X can be programmed for basic switch management functions such as port speed configuration, port aggregation, VLAN, Multiple Spanning Tree Protocol, bandwidth control and IGMP snooping.

By supporting port aggregation, the GS-6311-24T4X allows the operation of a high-speed trunk combined with multiple ports.  It enables up to 64 groups for trunking with a maximum of 8 ports for each group.  

Excellent Layer 2 to Layer 4 Traffic Control
The GS-6311-24T4X is loaded with powerful traffic management and WRR features to enhance services offered by telecoms. The WRR functionalities include wire-speed Layer 4 traffic classifiers and bandwidth limitation which are particularly useful for multi-tenant unit, multi-business unit, Telco, or network service applications. It also empowers the enterprises to take full advantage of the limited network resources and guarantees the best in VoIP and video conferencing transmission. 

Powerful Network Security
The GS-6311-24T4X offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications. Its protection mechanism also comprises 802.1x Port-based, MAC-based and web-based user and device authentications, which can be deployed with RADIUS, to ensure the port level security and block illegal users.

Advanced IP Network Protection
The GS-6311-24T4X also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrators can now construct highly-secure corporate networks with considerably less time and effort than before.
