Model	SG220-26-K9-EU
Switching capacity and forwarding rate	Capacity in Millions of Packets per Second (mpps) (64-byte packets): 38.69 Switching Capacity in Gigabits per Second (Gbps): 52
Jumbo frames	Frame sizes up to 9216 supported
MAC table	Up to 8192 MAC addresses
Total system ports	26 Gigabit Ethernet
RJ-45 ports	24 Gigabit Ethernet
Uplink ports	2 Gigabit Ethernet combo
Layer 2 Switching
Spanning Tree Protocol (STP)	Standard 802.1d STP support Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default
Port grouping	Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP): Up to 8 groups, Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation
VLAN	Support for up to 256 VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN
Auto voice VLAN	Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS
QinQ VLAN	VLANs transparently cross a service provider network while isolating traffic among customers
Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)	Protocols for automatically propagating and configuring VLANs in a bridged domain
Head-Of-Line (HOL) blocking	HOL blocking prevention
Loopback detection	Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP.
Automatic Media-Dependent Interface Crossover (MDIX)	Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.
Security
ACLs	Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag Support up to 512 rules
Port security	Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses
IEEE 802.1X (authenticator role)	802.1X: RADIUS authentication; guest VLAN;
RADIUS, TACACS+	Supports RADIUS and TACACS authentication; switch functions as a client
MAC address filtering	Supported
Storm control	Broadcast, multicast, and unknown unicast
DoS protection	DOS attack prevention
STP Bridge Protocol Data Unit (BPDU) Guard	This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port
Spanning Tree Loop Guard	This feature provides additional protection against Layer 2 forwarding loops (STP loops).
Secure Shell (SSH) Protocol	SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL)	SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
Quality of Service
Priority levels	8 hardware queues
Scheduling	Strict priority and weighted round-robin (WRR) Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)
Class of service	Port based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ)
Rate limiting	Ingress policer, per VLAN and per port
Environmental
Dimensions (W x H x D)	440 x 44 x 201 mm
Unit weight	2.81 kg
Power	100 to 240V 50 to 60 Hz, internal
