PD1-S31-9xxx Series New Generation of Aggregation 10G Switches

Carrier-Level QoS Policies

- Supports priority retagging and complicated flow classification based on VLAN, MAC, source address, destination address, IP or priority to better streamline carrier’s services. Supports flexible bandwidth control policies and supports port-/flow-based flow limit, and ensuring the line speed forwarding of each port to make sure the high quality of video, audio and data services.

- Supports 8 priority queues by each port. Supports multiple queue schedule algorithms such as SP, WRR, or “P plus WRR”.

Varied Service Characteristics

- Supports layer-2 and layer-3 multicast routing protocol, which enable the device can access to IPTV, HD video surveillance and HD video conference.

- Supports layer-3 routing protocol and super-large routing table capacity, which enables the device is available in large campus networks, enterprise networks and industry networks.

- Supports MPLS multi-VRF and layer-2 VPN.

Versatile IPv6 Solution

- Supports the IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6, path MTU discovery, DHCPv6, etc. Supports Ping, Traceroute, Telnet, SSH, ACL. Supports MLD, MLD Snooping, IPv6 static routing, RIPng, OSPFv3 and BGP4+, etc.

- Supports IPv6 tunnel: manual tunnel, automatic tunnel, GRE tunnel, 6to4, ISATAP. Supports IPv4 transits to IPv6: IPv6 manual tunnel, automatic tunnel, 6 to 4 tunnel, ISATAP tunnel.

Industrial Ethernet Ring with Zero Delay and Zero Packet Loss

- Supports industry-level EAPS and ERPS, and their protection recovery time is less than 50ms. Their high reliability is represented by the null packet loss, which has

been proved by many years of application in the Grid, rail transportation and defense systems.

Complete Security Mechanism

- Equipment-Level Security: The advanced hardware infrastructure design realizes the level-based packet schedule and packet protection, prevents DoS-/TCPrelated SYN Flood, UDP Flood, Broadcast Storm or large traffic attacks, and supports level-based command line protection, endowing different levels of users with different management permissions. Security Authentication Mechanism: IEEE 802.1x, Radius and Tacacs+Enhanced Service Security Mechanism: supports the plaintext or MD5 authentication of relevant routing protocol, URPF, deep inspection of hardware packet, control packet and data packet and filtering technology.

Innovative Energy-Saving Design

- Intelligent power management: The power system of PD1-S31-9xxx series supports real-time monitoring the device and the slow-start. It is also power-saving.

- Intelligent fan management system: The fan system of PD1-S31-9xxx series supports automatic speed regulation, which efficiently slow the fan speed and mitigate

the noise. Complies with the international standard IEEE 802.3a

Flexible and Convenient Management and Maintenance

- Supports management modes such as the console port, Telnet, SSH, etc.

- Supports the WEB management mode, which is easy and efficient so that it makes installation and debugging convenient.

- Supports TFTP-patterned file upload/download management.

- Supports ISSU (In-Service Software Upgrade). Supports SNMP and NMS smart network management platform to realize automatic equipment discovery, network topology management, equipment configuration management, performance data statistics and analysis and trouble management.
