PLANET Layer 3 24-Port 10/100/1000T + 4-Port 10G SFP+ Managed Ethernet Switch

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 15ms 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.
