The QuantaMesh T5016-LB8D can be managed through an industry standard command-line Interface (CLI) which reduces training and operating costs. A user friendly Web GUI is provided via a standard Web browser for switch management. The QuantaMesh T5016-LB8D also supports Simple Network Management Protocol (SNMP) both from standard MIB and private MIB for easy configuration, monitoring, and remote management by the network administrator. The Auto-Installation feature implemented in the QuantaMesh T5016-LB8D helps centralized management to simplify deployment of a truly plug-and-play experience. With the evolution from IPv4 to IPv6, the QuantaMesh T5016-LB8D is a IPv6 integrated management device.
The QuantaMesh T5016-LB8D is designed for high availability from both hardware and software perspective. Key features include:
  • 1+1 hot-swappable power supplies
  • Out-of-band management supported
  • 802.1D, 802.1w, and 802.1s supported
  • Up to 8 ports per link aggregation group (LACP) and up to 64 groups
  • Multi-chassis LAG (MLAG) for preventing the risks of single point failure
  • Up to 32 paths ECMP routing for load balancing and redundancy
  • Virtual Router Redundancy Protocol supported
High-Performance L2/L3 access deployments

With 16 QSFP+ ports in the front panel and in the compact 1U form factor, front to back or back to front airflow design, the QuantaMesh T5016-LB8D is ideal for top-of-rack deployments in high-performance, highly demanding datacenters. The 1.28 terabits per second switching capacity and 960Mpps forwarding rate with low power consumption make the QuantaMesh T5016-LB8D a powerful solution to aggregate high-performance servers in the datacenter.
Advanced IPv4 and IPv6 routing

The QuantaMesh T5016-LB8D is a fully layer 2 and layer 3 routing switch that supports advanced IPv4 and IPv6 routing features such as RIP v1/v2, OSPF/ECMP, RIPng and OSPFv3. The multicast routing features for IGMP v1/v2/v3, DVMRP, PIM-DM/SM, MLD v1/v2 and PIM-DM6/SM6 are all supported in the QuantaMesh T5016-LB8D.
Datacenter application

The QuantaMesh T5016-LB8D is a special IEEE DCB-based switch delivering a high-performance solution to integrate server edge access. The key features include:
  • Congestion Notification (CN, 802.1Qau)
  • Enhanced Transmission Selection (ETS, 802.1Qaz)
  • Priority-based Flow Control (PFC, 802.1Qbb)
  • Datacenter Bridging Extension (DCBX, 802.1Qaz)
  • FCoE Initiation Protocol (FIP) snooping
