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
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 LAG
VLAN
Support for up to 256 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.
Auto voice capabilities deliver 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 4K multicast groups (source-specific multicasting is also supported)
