Layer 2 switching

Spanning Tree Protocol

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); 16 instances are supported

Port grouping/link aggregation

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

VLAN

Support for up to 4094 active VLANs simultaneously; port-based and 802.1Q tag-based VLANs; MAC-based VLAN

Management VLAN

Private VLAN with promiscuous, isolated, and community port

Guest VLAN, unauthenticated VLAN, protocol-based VLAN, IP subnet-based VLAN, CPE VLAN

Dynamic VLAN assignment using RADIUS server along with 802.1x client authentication

Voice VLAN

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

Q-in-Q

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

GVRP/GARP

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain

Unidirectional Link Detection (UDLD)

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

DHCP relay at Layer 2

Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP option 82

IGMP (versions 1, 2, and 3) snooping

Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 4K 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

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

HOL blocking

Head-Of-Line (HOL) blocking

Layer 3

IPv4 routing

Wirespeed routing of IPv4 packets

Up to 8K static routes and up to 256 IP interfaces

IPv6 routing

Wirespeed routing of IPv6 packets

Layer 3 interface

Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface

CIDR

Support for classless interdomain routing

DHCP server

Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/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 BOOTP/DHCP packets

Stacking

Hardware stack

Up to 4 units in a stack. Up to 208 ports managed as a single system with hardware failover

High availability

Fast stack failover delivers minimal traffic loss. Support link aggregation across multiple units in a stack

Plug-and-play stacking configuration/management

Master/backup for resilient stack control

Autonumbering

Hot swap of units in stack

Ring and chain stacking options, autostacking port speed, flexible stacking port options

High-speed stack interconnects

Cost-effective high-speed 10G fiber and copper interfaces. Support LAG as stacking interconnects for even higher bandwidth

Security

SSH

SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported

SSL

Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch

IEEE 802.1X (authenticator role)

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 BPDU Guard

A security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (BPDU) Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops

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 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 preceding features (DHCP snooping, IP Source Guard, and Dynamic ARP inspection) work together to prevent DoS attacks in the network, thereby increasing network availability

Secure Core Technology (SCT)

Makes sure 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 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

Private VLAN

Private VLAN provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users’ traffic; supports multiple uplinks

Port security

Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses

RADIUS/TACACS+

Supports RADIUS and TACACS authentication. Switch functions as a client

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
