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 |
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 |
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 |

IPv4 routing |
Security |
Secure Shell (SSH) Protocol |
