Layer 2 Switching
MAC table	Up to 8,192 MAC addresses
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 VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN
Auto Voice VLAN	VLANs transparently cross a service provider network while isolating traffic among customers
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 9216 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.
Automatic Media-Dependent Interface Crossover (MDIX)	Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.
