S5821 48-Port 10GbE L3 Data Center Switch – Technical Specifications

Parameter Category	Specification Details
Model Number	S5821 (Series Name, e.g., S5821-48XS)
Switch Type	Fully Managed Layer 3 Data Center / Core Switch
Hardware Ports	48 x 10G SFP+ ports 6 x 40G QSFP+ uplink ports or 48 x 10G SFP+ ports 4 x 100G QSFP28 uplink ports (The “21” often signifies a high-density 48-port 10G design with high-speed uplinks)
Port Breakout	Uplink ports support breakout functionality: • A 40G QSFP+ port can break out into 4x 10G SFP+ ports. • A 100G QSFP28 port can break out into 4x 25G or 2x 50G ports. This provides immense flexibility for uplink configuration.
Switching Capacity	~1.76 Tbps (Terabits per second) or higher (non-blocking) Calculated: (48x10G + 6x40G) x 2 = (480 + 240) x 2 = 1.44 Tbps. With 100G uplinks, capacity is higher.
Forwarding Rate	~1,080 Mpps (Million packets per second) or higher
MAC Address Table	256K entries
Packet Buffer Memory	32 MB+ (Deep buffers are common for data center switches)
Jumbo Frame Support	12KB
