Layer 2 switching
Spanning Tree Protocol (STP)	Standard 802.1d spanning tree support
	Fast convergence using 802.1w (Rapid Spanning Tree Protocol [RSTP]), enabled by default Multiple spanning tree instances using 802.1s (MSTP); 8 instances are supported
	Per-VLAN Spanning Tree Plus (PVST+); 126 instances are supported
	Rapid PVST+ (RPVST+); 126 instances are supported
Port grouping/link aggregation	Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
	Up to 4 groups
	Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad Link Aggregation Group (LAG)
VLAN	Support for up to 255 active VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN
	Guest VLAN
	Auto Surveillance VLAN (ASV)
Voice VLAN	Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch deployment of voice endpoints and call control devices
Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)	Enable automatically propagation and configuration of VLANs in a bridged domain
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping	Limits bandwidth-intensive multicast traffic to only the requesters; supports 255 multicast groups (source-specific multicasting is also supported)
IGMP querier	Used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
Head-of-Line (HOL) blocking	HOL blocking prevention
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
Layer 3 routing
IPv4 routing	Wire-speed routing of IPv4 packets
IPv4 routing	Up to 32 static routes and up to 16 IP interfaces
IPv6 routing	Wire-speed routing of IPv6 packets
Layer 3 interface	Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
Classless Interdomain Routing (CIDR)	Support for CIDR
Dynamic Host Configuration Protocol (DHCP) relay at Layer 3	Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay	Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BootP)/DHCP packets
Security
Secure Sockets Layer (SSL)	Encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch
SSH Protocol	SSH is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH v1 and v2 are supported.
IEEE 802.1X (authenticator role)	RADIUS authentication, guest VLAN, single/multiple host mode, and single/multiple sessions
STP loopback guard	Provides additional protection against Layer 2 forwarding loops (STP loops)
Secure Core Technology (SCT)	Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received
Secure Sensitive Data (SSD)	A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices and a secure auto-configuration. Access to view the sensitive data as plain text or encrypted is provided according to the user- configured access level and the access method of the user
Trustworthy systems	Trustworthy systems provide a highly secure foundation for Cisco products
Trustworthy systems	Run-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC])
Port security	Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses
RADIUS	Supports RADIUS authentication for management access. Switch functions as a client
Storm control	Broadcast, multicast, and unknown unicast
DoS prevention	DoS attack prevention
Multiple user privilege levels in CLI	Level 1, 7, and 15 privilege levels
ACLs	Support for up to 512 rules
	Drop or rate limit based on source and destination MAC, VLAN ID, IPv4 or IPv6 address, IPv6 flow label, 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; ACL can be applied on both ingress and egress sides
	Time-based ACLs supported
Quality of service
Priority levels	8 hardware queues
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)/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
IPv6
IPv6	IPv6 host mode IPv6 over Ethernet Dual IPv6/IPv4 stack
	IPv6 Neighbor Discovery (ND)
	IPv6 stateless address auto-configuration
	Path Maximum Transmission Unit (MTU) discovery Duplicate Address Detection (DAD)
	ICMP version 6
	IPv6 over IPv4 network with Intrasite Automatic Tunnel Addressing Protocol (ISATAP) support
	USGv6 and IPv6 Gold Logo certified
IPv6 QoS	Prioritizes IPv6 packets in hardware
IPv6 ACL	Drop or rate-limit IPv6 packets in hardware
Multicast Listener Discovery (MLD v1/2) snooping	Delivers IPv6 multicast packets only to the required receivers
