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
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 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).
VLANs transparently cross over a service provider network while isolating traffic among customers.
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 is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router.
Head-of-line (HOL) blocking.
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
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
Up to 4 units in a stack. Up to 208 ports managed as a single system with hardware failover
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.
SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported.
Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch.
Quality of service
8 hardware queues
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)
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.
SNMP versions 1, 2c, and 3 with support for traps, and SNMP v3 User-based Security Model (USM)
