Model SG220-50P-K9-EU
Performance
Switching capacity and forwarding rate Capacity in Millions of Packets per Second (mpps) (64-byte packets): 74.4
Switching Capacity in Gigabits per Second (Gbps): 100
Jumbo frames Frame sizes up to 9216 supported
MAC table Up to 8192 MAC addresses
Total system ports 50 Gigabit Ethernet
RJ-45 ports 48 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
Power over Ethernet
802.3af PoE or 802.3at PoE+ delivered over any of the RJ-45 network ports within the listed power budgets Switches support 802.3af, 802.3at, and Cisco pre-standard (legacy) PoE with maximum power of 30 W per port.
This applies to the following PoE-enabled models; the maximum number of ports providing PoE power simultaneously is determined by the total PoE budget for the switch listed as below:
PoE Power Budget: 375 W
Number of Ports That Support PoE: 48
Pre-standard PoE Support Cisco Pre-Standard PoE
Intelligent PoE power management Support the granular power negotiation with CDP/LLDP communication with PD devices after IEEE classification
