10GBASE-T Connections
Support low-latency, line-rate 10G Copper “BASE-T” technology with backward compatibility to Gigabit Ethernet and Fast Ethernet. Cost-effectively migrate current network to 10G capacity by utilizing the existing Cat 6 RJ45 short connections (up to 45m) and Cat 6a / Cat 7 connections up to 100m.
10GBASE-X SFP+ ports
Providing flexibility to uplink to 10G-capable core or aggregation switches that support fiber links. Backward compatible to Gigabit fiber. Support copper or fiber modules.
Multi-Gigabit Connections
Support line-rate 2.5G/5G "NBASE-T" technology with backward compatibility to Gigabit Ethernet and Fast Ethernet. Upgrade your current network without upgrading your existing cabling, thanks to Multi-Gigabit you will be able to run 5G and 2.5G over connections up to 100m.
Comprehensive QoS Features
Advanced controls for optimized network performance and better delivery of mission-critical traffic such as voice and video. Ingress and egress rate limiting allows for bandwidth shaping for mitigating network resources constraints or for optimizing guest access bandwidth on the network.
Port-based or 802.1p-based prioritization
Layer 3-based (DSCP) prioritization
Port-based ingress and egress rate limiting
IGMP Snooping
For improved network efficiency on delivering multicast traffic. Save cost and improve network efficiency by ensuring multicast traffic only reaches designated receivers without the need of an extra multicast router.
Loop Detection / Auto DoS Prevention
Detect accidental network loops and protect against DoS (Denial of Service) attacks.
Port-based & 802.1Q-based VLANs
Segment network into smaller groups for more secure and efficient use of network resources.
Port Trunking / Link Aggregation (LAG)
Build up bigger bandwidth to support aggregated uplink/downlink traffic.
Energy Effiecient Ethernet (IEEE 802.3az)
For maximum power savings and reduced energy costs.
Port Mirroring
For better and quicker network diagnostics and troubleshooting.
Cable Test
Easily identify bad Ethernet cables.
