||
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 (Also known as MVR) |
||
Q-in-Q VLAN |
VLANs transparently cross a service provider network while isolating traffic among customers |
||
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) |
Protocols for automatically propagating and configuring 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 blackholing 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 1K multicast groups (source-specific multicasting is also supported) |

||
Web Based Authentication |
Web based authentication provides network admission control through web browser to any host devices and operating systems. |
||
STP Bridge Protocol Data Unit (BPDU) Guard |
A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. |
||
STP Root Guard |
This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes. |
||
DHCP snooping |
Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server. |
||
IP Source Guard (IPSG) |
When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing. |
||
Dynamic ARP Inspection (DAI) |
The switch discards ARP packets from a port if there is no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. This prevents man-in-the-middle attacks. |
||
IP/Mac/Port Binding (IPMB) |
The features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) above work together to prevent DOS attacks in the network, thereby increasing network availability. |
||
Secure Core Technology (SCT) |
Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received. |
||
Secure Sensitive Data (SSD) |
A mechanism to manage sensitive data (such as passwords, keys, etc) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user configured access level and the access method of the user. |
||
Layer 2 isolation Private VLAN Edge (PVE) with community VLAN |
PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks. |
||
Port security |
The ability to lock Source MAC addresses to ports, and limits the number of learned MAC addresses. |
||
RADIUS/TACACS+ |
Supports RADIUS and TACACS authentication. Switch functions as a client. |
||
Storm control |

||
RADIUS accounting |
