| 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 |
