Guest VLAN Unauthenticated VLAN

Dynamic VLAN assignment via Radius server along with 802.1x client authentication

CPE VLAN

Voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS.

Auto voice capabilities deliver network-wide 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 (Also known as MVR)

Q-in-Q VLAN

VLANs transparently cross a service provider network while isolating traffic among customers

Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP)

Protocols for automatically propagating and configuring VLANs in a bridged domain

Unidirectional Link Detection (UDLD)

UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks

Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2

Relay of DHCP traffic to DHCP server in 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; supports 1K 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

Jumbo Frames

Up to 9K (9216) bytes

Support for CIDR

Layer 3 Interface

Configuration of layer 3 interface on physical port, LAG, VLAN interface or Loopback interface

Relay of DHCP traffic across IP domains

User Datagram Protocol (UDP) relay

Support for DHCP options

Security

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

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

Web Based Authentication

Web based authentication provides network admission control through 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.

STP Root Guard

This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes.

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 is 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 (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, 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

The ability to lock Source 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

RADIUS accounting

The RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session.

DoS prevention

Denial-of-Service (DOS) attack prevention

ACLs
