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) ● 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. 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 |
|||||||
