Feature
Description
Layer 2 switching
Spanning Tree Protocol
(STP)
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); 8 instances are supported
Per-VLAN Spanning Tree Plus (PVST+); 126 instances are supported
Rapid PVST+ (RPVST+); 126 instances are supported
Port grouping/link
aggregation
Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
● Up to 4 groups
● Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad Link Aggregation Group
(LAG)
VLAN
Support for up to 255 active VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
Management VLAN
Guest VLAN
Voice VLAN
Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate
levels of QoS. Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch
deployment of voice endpoints and call control devices
Generic VLAN Registration
Protocol (GVRP) and
Generic Attribute
Registration Protocol
(GARP)
Protocols for automatically propagating and configuring VLANs in a bridged domain
IGMP (versions 1, 2, and 3)
snooping
Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to
only the requesters; supports 255 multicast groups (source-specific multicasting is also
supported)
IGMP querier
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 prevention
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.
Layer 3 routing
IPv4 routing
Wire-speed routing of IPv4 packets
Up to 32 static routes and up to 16 IP interfaces
IPv6 routing
Wire-speed routing of IPv6 packets
Layer 3 interface
Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback
interface
Classless Interdomain
Routing (CIDR)
Support for CIDR
