Spanning Tree Protocol (STP) Standard 802.1d Spanning Tree support, enabled by default

Fast convergence using 802.1w (Rapid Spanning Tree [RSTP])

Multiple Spanning Tree instances using 802.1s (MSTP)

16 instances are supported

Port grouping 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 link aggregation

Load balance based on source and destination MAC address, or source and destination MAC/IP

VLAN Support for up to 256 Virtual Local Area Networks (VLANs) simultaneously

Port-based and 802.1Q tag-based VLANs

Management VLAN

Guest VLAN

Auto voice VLAN Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS

QinQ VLAN VLANs transparently cross a service provider network while isolating traffic among customers

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) Protocols for automatically propagating and configuring VLANs in a bridged domain

Head-of-Line (HOL) blocking HOL blocking prevention

Jumbo frame Frame sizes up to 9,216 supported

Loopback detection 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.
