Voice VLANVoice traffic is automatically assigned khổng lồ a voice-specific VLAN and treated with appropriate levels of QoS Auto lớn voice capabilities deliver networkwide zero-touch deployment of voice endpoints & Hotline control devices
Multicast TV VLANMulticast TV VLAN allows the single multicast VLAN khổng lồ be shared in the network while subscribers remain in separate VLANs (also known as MVR)
Q-in-Q VLANVLANs transparently cross a service provider network while isolating traffic aước ao 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 link caused by incorrect wiring or cable/port faults to prsự kiện forwarding loops & blackholing of traffic in switched networks
Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2Relay of DHCPhường traffic to DHCPhường VPS in different VLAN; works with DHCP Option 82
Internet Group Management Protocol (IGMP) versions 1, 2, & 3 snoopingIGMP. limits bandwidth-intensive sầu multicast traffic to only the requesters; supports 1K multicast groups (source-specific multicasting is also supported)
IGMP QuerierIGMP.. querier is used khổng lồ tư vấn a Layer 2 multicast tên miền of snooping switches in the absence of a multicast router
Head-Of-Line (HOL) blockingHOL blocking prevention
Loopbaông xã DetectionLoopbaông xã 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

Security
Secure Shell (SSH) ProtocolSSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL)SSL support: Encrypts all HTTPS traffic, allowing highly secure access lớn the browser-based management GUI in the switch
IEEE 802.1X (Authenticatorrole)802.1X: RADIUS authentication & accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode & single/multiple sessions Supports time-based 802.1X Dynamic VLAN assignment
Web-based authenticationWeb based authentication provides network admission control through web browser lớn any host devices và operating systems
STPhường. Bridge Protocol Data Unit (BPDU) GuardA security mechanism lớn 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 GuardThis prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes
DHCPhường snoopingFilters out DHCP. messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP.. Servers
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 sầu not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing
Dynamic ARPhường. Inspection (DAI)The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks
IP/MAC/Port Binding (IPMB)The preceding features (DHCP.. Snooping, IPhường Source Guard, and Dynamic ARP.. Inspection) work together to lớn prevent DOS attacks in the network, thereby increasing network availability
Secure Vi xử lý Core Technology (SCT)Makes sure that the switch will receive and process management & protocol traffic no matter how much traffic is received
Secure Sensitive sầu Data (SSD)A mechanism to manage sensitive sầu data (such as passwords, keys, & so on) securely on the switch, populating this data to lớn other devices, và secure autoconfig. Access lớn view the sensitive sầu data as plaintext or encrypted is provided according lớn the user-configured access level & the access method of the user
Layer 2 isolation Private VLAN Edge (PVE) with community VLANPVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks
Port securityThe ability to lớn lochồng source MAC addresses khổng lồ ports & limits the number of learned MAC addresses
RADIUS/TACACS+Supports RADIUS và TACACS authentication. Switch functions as a client
Storm controlBroadcast, multicast, & unknown unicast
RADIUS accountingThe RADIUS accounting functions allow data to lớn be sent at the start và end of services, indicating the amount of resources (such as time, packets, bytes, & so on) used during the session
