Feature

Description

Port grouping/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 link aggregation

VLAN

Support for up to 4,094 VLANs simultaneously

Port-based and 802.1Q tag-based VLANs; MAC-based VLAN; protocol-based VLAN; IP

subnet-based VLAN

Management VLAN

Private VLAN with promiscuous, isolated, and community port

Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks

Guest VLAN, unauthenticated VLAN

Dynamic VLAN assignment via RADIUS server along with 802.1x client authentication

CPE 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 network wide 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 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 configuring of Ethertype (Tag Protocol Identifier [TPID]) of the

S-VLAN tag

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

Generic VLAN Registration

Protocol (GVRP)/Generic

Attribute Registration

Protocol (GARP)

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol

(GARP) enable automatic propagation and configuration of VLANs in a bridged domain

Unidirectional Link

Detection (UDLD)

UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring

or cable/port faults to prevent forwarding loops and black holing of traffic in switched

networks
