| 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. |
| SNMP |
SNMP versions 1, 2c, and 3 with support for traps, and SNMP v3 User-based Security Model (USM) |
