Product specifications

• Forwarding rate in millions of packets per second (mpps; 64-byte packets) : 14.88
• Switching capacity in Gigabits per second (Gbps) : 20
• Packet Buffer : 4.1Mb
• MAC table : Up to 8,192 Media Access Control (MAC) addresses
• Spanning Tree Protocol (STP) : Standard 802.1d Spanning Tree support, enabled by default Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]) Multiple Spanning Tree instances using 802.1s (MSTP) 16 instances are supported
• 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 Load balance based on source and destination MAC address, or source and destination MAC/IP
• VLAN : Support for up to 256 Virtual Local Area Networks (VLANs) simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN
• 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)
• Head-of-Line (HOL) blocking
• Jumbo frame : Frame sizes up to 9,216 supported
• 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)
• 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, Transmission Control Protocol (TCP)/ User Datagram Protocol (UDP) source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, Internet Group Management Protocol (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: Remote Authentication Dial-in User Service (RADIUS) authentication; guest VLAN; Single-host, multiple-host, and multisession mode
• RADIUS, TACACS+ : Supports RADIUS and Terminal Access Controller Access Control System (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
• Qos
• Web browser : Chrome, Firefox, Edge, Safari
