Product overview:
  • PD1-S81-6121 is a new generation of aggregation 10GE switch introduced by Terrabit Networks. It is targeted at the IP MAN (metropolitan area network), campus networks and enterprise networks. It is developed on the basis of high performance hardware and TerOS - a software platform with Terrabit own independent intellectual property rights. It supports multiple services like IPv6, MPLS, VPN and network security based on L2/L3/L4 wirespeed switching service. It also supports nonstop upgrade, continuous forwarding, graceful restarting and redundancy protection. 
  • It supports 8 GE ports and 12 10GE ports..
Carrier-Level Aggregation Layer-3 Ethernet Switch Innovative BVSS (Terrabit Virtual Switch System):
  • PD1-S81-6121 can virtualize multiple physical devices into one. The performance, reliability and management of the virtual system are superior to the physical ones.
Improved Performance:
  • BVSS makes full use of each link in the physical devices, which avoids STP blocking the link and protects the original link to the maximum extent.
High Reliability:
  • Based on the advanced distribution mechanism and efficient cross-physical link aggregation link function, the logic control plane, service control plane and service data plane are separated. Thus, the device can support continuous layer3 routing forwarding, avoiding service interruption as a result of a single point of failure.
Easy Management:
  • BVSS realizes single IP management, greatly improving the networking efficiency and lowering the operating cost.
Carrier-level High Reliability:
  • PD1-S81-6121 supports STP/RSTP/MSTP, VRRP protocol, Ethernet ring protection, dual master-slave uplink protection and LACP link aggregation.
  • PD1-S81-6121 supports ISSU (In-Service Software Upgrade).
  • PD1-S81-6121 supports BFD mechanism.
  • PD1-S81-6121 supports Ethernet OAM mechanism, 802.3ah, 802.1ag and ITU-Y.1731.
  • High reliability (99.999%): MTTR of PD1-S81-6121 is 50ms, meeting the requirement of the carrier- level service.
Varied Service Features:
  • PD1-S81-6121 supports layer2 and layer3 multicast routing protocol, which enable the device can access to IPTV, HD video surveillance and HD video conference.
  • PD1-S81-6121 supports layer3 routing protocol and super-large routing table capacity, which enables the device is available in large campus networks, enterprise networks and industry net- works.
  • PD1-S81-6121 supports layer2 MPLS VPN.
  • Equipment-level security: The advanced hard- ware 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 level-based command line protection, endowing different levels of users with different management permissions.
  • Perfect security authentication mechanisms: IEEE802.1x, Radius and Tacacs+.
  • PD1-S81-6121 supports storm/multicast/unicast limit, ensuring the normal running of equipment in harsh network conditions.
  • PD1-S8-6121 supports perfect ring detection mechanism, ensuring the long-term stable running of network.
  • PD1-S81-6121 supports port isolation within the same VLAN, DHCP-Snooping, and IP+ MAC+ Port binding.
Versatile IPv6 Solution:
  • PD1-S81-6121 supports the IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6, path MTU discovery, DHCPv6, etc.
  • PD1-S81-6121 supports Ping, Traceroute, Telnet, SSH, ACL based on IPv6.
  • PD1-S81-6121 supports MLD, MLD Snooping, IPv6 static routing, RIPng, OSPFv3 and BGP4+, etc.
  • PD1-S81-6121 supports IPv6 tunnel: manual tunnel, automatic tunnel, GRE tunnel, 6to4 tunnel, ISATAP.
  • PD1-S81-6121 supports IPv4 transiting to IPv6: IPv6 manual tunnel, automatic tunnel, 6 to 4 tunnel, ISATAP tunnel.
Innovative Energy-saving Design:
  • Intelligent power management: The power system of PD1-S81-6121 supports real-time monitoring the device and the slow-start. It is also power-saving.
  • Configuration with previously stored configurations and perform rollback if needed. The system has the capability to store up to 128 versions of saved configurations.
  • Intelligent fan management system: The fan system of PD1-S81-6121automatic speed regulation, which efficiently slow the fan speed and mitigate the noise.
  • Comply with the international standard IEEE 802.3az.
