The QuantaMesh T3048-LY2R can be managed through industry standard command-line interface (CLI) which reduces the training and operating costs. A user friendly Web GUI is provided via a standard Web browser to manage. The QuantaMesh T3048-LY2R also supports Simple Network Management Protocol (SNMP) both from standard MIB and private MIB for network administrator to easily configure, monitor, and manage remotely. The Auto-Installation feature implemented in the QuantaMesh T3048-LY2R helps centralized management to simplify deployment of a truly plug-and-play experience. With the evolution from IPv4 to IPv6, the QuantaMesh T3048-LY2R is a IPv6 integrated management device.
High Availability

The QuantaMesh T3048-LY2R is designed for high availability from both hardware and software perspective. The key features include:
  • 1+1 hot-swappable power supplies
  • 2+1 hot-swappable fans
  • Out-of-band management supported
  • 802.1D, 802.1w, and 802.1s supported
  • Up to 32 ports per group (LACP) and up to 64 groups
  • Multi-chassis LAG 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 the compact 1U form factor, high density 48 1/10G SFP+ and 4 10/40G QSFP+ ports in the front panel, front to back or back to front airflow design, the QuantaMesh T3048-LY2R 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 T3048-LY2R a powerful solution to aggregate high-performance servers in the datacenter.
Advanced IPv4 and IPv6 Routing

The QuantaMesh T3048-LY2R is a full layer 2 and layer 3 routing switch that supports advanced IPv4 and IPv6 routing features such as RIP v1/v2, OSPF/ECMP, RIPng and OSFPv3. 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 T3048-LY2R.
Datacenter application

The QuantaMesh T3048-LY2R is an 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
