Grandstream GWN7821P 8 PORT POE 2 x 10G SFP+ LAYER 3 MULTI-GIGABIT SWITCH Managed

Grandstream GWN7821P 8-Port 2.5GbE Layer 3 Managed Stackable PoE++ Network Switch with 2 x 10G SFP+ & Console Port

The Grandstream GWN7821P is an eight-port Layer 3 managed and stackable multi-gigabit PoE switch for business networks requiring faster device connections, advanced control and high-power PoE. All eight 2.5GbE ports support up to 60W PoE++ within a 240W shared budget, while two 10G SFP+ ports provide high-bandwidth infrastructure links. An 80Gbps switching capacity, IPv4 and IPv6 routing, advanced traffic management, comprehensive security and flexible local, cloud and on-premise administration support scalable network deployment.

Key Features

• 8 x 2.5GbE PoE [Power over Ethernet] RJ45 ports and 1 x console port
• 2 x 10G SFP+ [Small Form-factor Pluggable Plus] ports supporting compatible single-mode, multi-mode or 10G RJ45 modules, or DAC cables up to 5m
• IEEE 802.3af/at/bt power delivery, with up to 60W PoE++ available per port within a 240W budget
• PoE schedules, port priorities, maximum power limits and LLDP-MED dynamic power negotiation
• 80Gbps switching capacity, 40Gbps non-blocking throughput, 59.52Mpps forwarding rate, 12Mb packet buffer and network latency below 4µs
• 16K MAC [Media Access Control] addresses, 4K VLANs [Virtual Local Area Networks] and jumbo frames up to 12KB
• IPv4 and IPv6 static and dynamic routing with RIP, RIPng, OSPF, OSPFv3, BGP, routing policies, DHCP server and DHCP relay
• Stacking [up to four switches managed as one], 32 link aggregation groups and spanning-tree support [prevents network loops]
• IGMP [Internet Group Management Protocol] and MLD [Multicast Listener Discovery] Snooping, QoS [Quality of Service] controls and up to 2K ACLs [Access Control Lists]
• 802.1X and MAC authentication, RADIUS, TACACS+, DHCP and DHCPv6 snooping, ARP inspection, IP and IPv6 Source Guard, port security and DoS protection

Multi-Gigabit PoE++ Connectivity
All eight RJ45 ports support network speeds up to 2.5Gbps and IEEE 802.3bt PoE++ output of up to 60W per port. Administrators can schedule power delivery, set port priorities and configure maximum power limits within the 240W budget, while LLDP-MED supports dynamic power negotiation with compatible devices.

Layer 3 Routing and Stacking
Static and dynamic IPv4 and IPv6 routing supports communication between network segments, with RIP, RIPng, OSPF, OSPFv3 and BGP available for different network requirements. Up to four compatible switches can form one logical stack for unified configuration and expansion, while link aggregation increases bandwidth and provides link resilience, including across stacked switches.

Network Segmentation and Traffic Control
Port-based, 802.1Q, MAC-based, protocol-based, Private and Voice VLANs provide flexible traffic separation. QoS prioritises important applications and controls bandwidth through traffic shaping and rate limiting. IGMP and MLD Snooping conserve bandwidth by directing multicast traffic only where required, while Ethernet, IPv4 and IPv6 ACLs control permitted and restricted traffic.

Secure and Flexible Management
Authentication, DHCP and DHCPv6 snooping, ARP inspection, IP and IPv6 Source Guard, port security and DoS protection help defend against unauthorised access, address spoofing and disruptive traffic. Local web, command-line, SNMP, GDMS Networking, GWN Manager and compatible GWN router management provide flexible administration. Dual hardware boot and dual system-file redundancy support reliable operation, while power, fan, CPU and memory monitoring, Ping, Traceroute, port mirroring, copper cable testing, RMON and Syslog assist fault-finding.
