• Supports the carrier-level Ethernet-ring protection protocol with a protection shift time of less than 50ms, STP/RSTP, link backup, and LACP link aggregation to cater to the requirements of high reliability
• Has powerful ACL functions to access and control of L2-L7 data, and provides carriers flexible and various policy control methods
• Supports In-Service Software Upgrade (ISSU) to ensure the unremitting data forwarding during system upgrade.
• Supports various L2 multicast functions, including IGMPSnooping, fast-leave and MVR.

• Supports 802.3AF/AT standard, built-in high power supply supports full-port AF full-load power supply
• Supports uninterrupted POE power supply for the device to hot reboot
• Supports to configure the priority of the power supply port to ensure priority power supply for important services
• Supports lightning protection for POE ports and power supplies

• Supports priority re-mapping and complicated flow classification based on VLAN, MAC, source address, destination address, IP protocol or priority to better streamline carrier’s services.
• Provides flexible bandwidth control policies, supports port-/flow-based flow limit, and ensures the line speed forwarding of each port to make sure the high quality of network services.
• Supports multiple queue schedule algorithms such as SP, WRR, or SP+WRR.

• Supports the IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6, path MTU discovery.
• Supports Ping, Traceroute, Telnet, SSH, ACL, meeting IPv6 networks device management requirements and service control requirements.

• Equipment-level security: The advanced hardware infrastructure design realizes the level-based packet schedule and packet protection, prevents DoS-/TCP-related SYN Flood, UDP Flood, Broadcast Storm or large traffic attacks, and supports levelbased command line protection, endowing different levels of users with different management permissions.
• Perfect security authentication mechanisms: IEEE 802.1x, Radius and TerTacacs+; Storm/ multicast/ unicast limit to ensure the normal running of devices in harsh network conditions.

• Supports management modes such as the console port, Telnet, SSH
• Supports the WEB management mode, which is easy and efficient so that it makes installation and debugging convenient
• Supports TFTP-based upload/download management
• Supports ISSU (In-Service Software Upgrade)
• Supports SNMP and Terrabit Networks NMS smart network management platform to realize automatic device discovery, network topology management, device configuration management, performance data statistics and analysis and trouble management
