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)

- Up to 8 groups

- Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG

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.

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

Wirespeed IPv6 static routing Up to 4K static routes and up to 200 IPv6 interfaces

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

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.

Quality of service

Priority levels 8 hardware queues

Scheduling Strict priority and weighted round-robin (WRR)

Class of service Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/ToS/DSCP based; DiffServ; classification and remarking ACLs, trusted QoS

Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)

Management

Web user interface Built-in switch configuration utility for easy browser-based device configuration (HTTP/HTTPS).

Supports simple and advanced mode, configuration, wizards, customizable dashboard, system maintenance, monitoring, online help, and universal search.
