Switching capacity (Gbps): 176

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); 8 instances are supported

Per-VLAN Spanning Tree Plus (PVST+); 126 instances are supported

Rapid PVST+ (RPVST+); 126 instances are supported

Port grouping and 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. Auto voice 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)

VLAN translation Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface, Customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN

Q-in-Q VLANs transparently cross over a service provider network while isolating traffic among customers

Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs

Selective Q-in-Q also allows configuration of the EtherType (TPID) of the S-VLAN tag

Layer 2 protocol tunneling over Q-in-Q is also supported

GVRP/GARP Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain
