Layer 2 Switching

Spanning Tree Protocol

Standard 802.1d Spanning Tree support

Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default

Multiple Spanning Tree instances using 802.1s (MSTP); 8 instances are supported

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

Port grouping/link aggregation

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

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. Auto voice capabilities deliver 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

Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2

Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82

Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping

IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 2K multicast groups (source-specific multicasting is also supported)

IGMP Querier

IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router

Head-of-Line (HOL) blocking

HOL blocking prevention

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

Layer 3

IPv4 routing

Wirespeed routing of IPv4 packets

Up to 990 static routes and up to 128 IP interfaces

IPv6 routing

Wirespeed routing of IPv6 packets

Layer 3 Interface

Configuration of Layer 3 interface on physical port, Link Aggregation (LAG), VLAN interface, or loopback interface

Classless Interdomain Routing (CIDR)

Support for classless interdomain routing

RIP v2

Support for Routing Information Protocol version 2 for dynamic routing

Policy-Based Routing (PBR)

Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 Access Control List (ACL)

DHCP Server

Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes

Support for DHCP options

DHCP relay at Layer 3

Relay of DHCP traffic across IP domains

User Datagram Protocol (UDP) relay

Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BOOTP)/DHCP packets
