Layer 2 Switching
Spanning Tree Protocol: Standard 802.1d Spanning Tree support Fast convergence using 802.1w (Rapid Spanning Tree), enabled by default Multiple Spanning Tree instances using 802.1s

VLAN: Support for up to 256 VLANs simultaneously (out of 4096 VLAN IDs) Port-based and 802.1Q tag-based VLANs MAC-based VLAN Management VLAN Private VLAN Edge, also known as protected ports, with multiple uplinks Guest VLAN Unauthenticated VLAN
Voice VLAN: Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS
Q-in-Q VLAN: VLANs transparently cross a service provider network while isolating traffic among customers
Generic VLAN Registration Protocol/Generic Attribute Registration Protocol: Protocols for automatically propagating and configuring VLANs in a bridged domain
Dynamic Host Configuration Protocol Relay at Layer 2: Relay of DHCP traffic to DHCP server in different VLAN. Works with DHCP Option 82
Internet Group Management Protocol Versions 1, 2 and 3 Snooping: IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups (source-specific multicasting is also supported)
IGMP Querier: IGMP querier is 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
Layer 3
IPv4 Routing: Wirespeed routing of IPv4 packets Up to 32 static routes and up to 32 IP interfaces
Classless Inter-Domain Routing: Support for CIDR
DHCP Relay at Layer 3: Relay of DHCP traffic across IP domains
User Datagram Protocol Relay: Relay of broadcast information across Layer 3 domains for application discovery or relaying of BootP/DHCP packets
Security
Secure Shell Protocol: SSH secures Telnet traffic to and from the switch; SSH v1 and v2 are supported
Secure Sockets Layer: SSL Support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
STP Bridge Protocol Data Unit Guard: A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port
STP Root Guard: This prevents edge devices not in the network administrator's control from becoming Spanning Tree
DHCP Snooping: Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server
IP Source Guard (IPSG): When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing
Dynamic ARP Inspection (DAI): The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. This prevents man-in-the-middle attacks
IP/Mac/Port Binding (IPMB): The features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) above work together to prevent DOS attacks in the network, thereby increasing network availability
Secure Core Technology: 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, etc.) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user configured access level and the access method of the user
Layer 2 Isolation Private VLAN Edge (PVE) with community VLAN: PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks
Port Security: Locks MAC addresses to ports, and limits the number of learned MAC addresses
RADIUS/TACACS+: Supports RADIUS and TACACS authentication. Switch functions as a client
Storm Control: Broadcast, multicast, and unknown unicast
DoS Prevention: DoS attack prevention
Congestion Avoidance: A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization
ACLs: Support for up to 512 rules Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point/IP precedence, TCP/ UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol packets, IGMP packets, TCP flag
Quality of Service (QoS)
Priority Levels: 4 hardware queues
Scheduling: Strict priority and weighted round-robin 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/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
IPv6: IPv6 host mode IPv6 over Ethernet Dual IPv6/IPv4 stack IPv6 neighbor and router discovery IPv6 stateless address auto-configuration Path maximum transmission unit discovery Duplicate address detection ICMP version 6 IPv6 over IPv4 network with Intra-Site Automatic Tunnel Addressing Protocol support
IPv6 QoS: Prioritize IPv6 packets in hardware
IPv6 ACL: Drop or rate, limit IPv6 packets in hardware

IPv4 and IPv6 Dual Stack: Coexistence of both protocol stacks to ease migration
Firmware Upgrade: Web browser upgrade (HTTP/HTTPS) and TFTP Upgrade can be initiated through console port as well Dual images for resilient firmware upgrades
Port Mirroring: Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port. A single session is supported
VLAN Mirroring: Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up to 8 source VLANs can be mirrored to one destination port. A single session is supported
Dynamic Host Configuration Protocol (Options 66, 67, 82, 129 and 150): DHCP Options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-configuration (with configuration file download), DHCP relay, and hostname
Secure Copy (SCP): Securely transfer files to and from the switch
Auto-configuration with Secure Copy (SCP) File Download: Enables secure mass deployment with protection of sensitive data
Text-Editable Config Files: Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment

Power Efficiency
Energy Detect: Automatically turns off power off on Gigabit Ethernet RJ-45 port when detecting link down Active mode is resumed without loss of any packets when the switch detects the link up
Cable Length Detection: Adjusts the signal strength based on the cable length. It reduces the power consumption for cables shorter than 10 m
Disable Port LEDs: LEDs can be manually turned off to save on Energy
General Features
Jumbo Frames: Frame sizes up to 9 KB supported on 10/100 and Gigabit interfaces
MAC Table: Up to 16K (16384) MAC addresses
Discovery
Bonjour: Bonjour locates devices such as printers, other computers and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records
Link Layer Discovery Protocol (802.1ab) with LLDP-MED Extensions: LLDP allows the switch to advertise its identification, configuration and capabilities to neighboring devices that store the data in a MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones
Cisco Discovery Protocol (CDP): CDP is a proprietary data link layer and network layer protocol which is used to share information about other directly connected Cisco equipment, such as the operating system version and IP address
