Private VLAN with promiscuous, isolated, and community port
Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks Guest VLAN, unauthenticated VLAN
Dynamic VLAN assignment via RADIUS server along with 802.1X client authentication Customer premises equipment (CPE) 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
Multicast TV VLAN Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR)
VLAN translation Support for VLAN one-to-one mapping, in which customer VLANs (C-VLANs) on an edge interface are mapped to service provider VLANs (S-VLANs), and the original C-VLAN tags are replaced by the specified S-VLAN
Q-in-Q VLANs transparently cross a service provider network while isolating traffic among customers
Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs
Selective Q-in-Q also allows configuring of the Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag
Layer 2 protocol tunneling over Q-in-Q is also supported
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) GVRP and GARP enable automatic propagation and configuration of VLANs in a bridged domain
Unidirectional Link UDLD monitors physical connections to detect unidirectional links caused by incorrect
Detection (UDLD) wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks
DHCP relay at Layer 2 Relay of DHCP traffic to a DHCP server in a different VLAN; works with DHCP Option 82
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping IGMP limits bandwidth-intensive multicast traffic to only the requesters; it supports 2000 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
IGMP proxy The IGMP proxy provides a mechanism for multicast forwarding based on IGMP membership information without the need for more complicated multicast routing protocols
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
Layer 3 IPv4 routing Wire-speed routing of IPv4 packets
Up to 990 static routes and up to 128 IP interfaces
IPv6 routing Wire-speed routing of IPv6 packets
Layer 3 interface Configuration of a Layer 3 interface on a physical port, LAG, VLAN interface, or loopback interface
Classless Interdomain Routing (CIDR) Support for CIDR
Routing Information Protocol (RIP) v2 Support for RIP v2 for dynamic routing
Policy-Based Routing (PBR) Flexible routing control to direct packets to a different next hop based on an IPv4 or IPv6 Access Control List (ACL)
DHCP server Switch functions as an IPv4 DHCP server, serving IP addresses for multiple DHCP pools or scopes
Support for DHCP options
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 Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (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
IEEE 802.1X (authenticator role) 802.1X: RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single/multiple host mode, and single/multiple sessions
Supports time-based 802.1X, dynamic VLAN assignment, and MAC authentication
IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)
Web-based authentication Web-based authentication provides network admission control through a web browser to any host devices and operating systems
STP Bridge Protocol Data Unit (BPDU) 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. This avoids accidental topology loops
STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP root nodes
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP servers
IP Source Guard (IPSG) When IPSG 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 addresses in the ARP packet. This prevents man-in-the-middle attacks
IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together to prevent Denial-of-Service (DoS) attacks in the network, thereby increasing network availability
Secure Core Technology (SCT) Makes sure that the switch will receive a
