Thông số kỹ thuật

Giao thức Spanning:

Hỗ trợ chuẩn 802.1d Spanning Tree

Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default

8 instances are supported

Multiple Spanning Tree instances using 802.1s (MSTP)

Port grouping: 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 4096 VLANs simultaneously Port-based and 802.1Q tag-based VLANs MAC-based VLAN Management VLAN 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 networkwide 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)

IPv4 routing:

Wirespeed routing of IPv4 packets Up to 1K static routes and up to 128 IP interfaces

IPv6 routing: Wirespeed routing of IPv6 packet

Classless Interdomain Routing (CIDR): Support for CIDR

Giao diện Layer 3: Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface

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 bootP/DHCP packets

DHCP Server: Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes Support for DHCP options
