Layer 2 switching 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

VLAN Support for up to 256 Virtual Local Area Networks (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
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) 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, 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 Priority levels 8 hardware queues per port
Scheduling Strict priority and Weighted Round-Robin (WRR) queue assignment based on 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), and DSCP-based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS
Rate limiting Ingress policer; egress shaping and rate control; per VLAN, per port, and flow-based
Congestion avoidance A TCP congestion avoidance algorithm is required to reduce and prevent global TCP loss synchronization.
Multicast Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 Snooping IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups
IGMP querier IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
