Our existing design is quite simple, it consists of several switches acting as layer 2 (around 6-7) and all of them are connected to a switch through single interface trunk ports.
You are advised to configure port isolation on the interfaces connecting the access switch to terminals. This configuration secures user communication and prevents invalid broadcast packets from
Switches at this layer are optimized for port density rather than raw switching power. They typically include features like Power over Ethernet (PoE), port security, and VLAN assignment.
The loop-free U topology design provides a Layer 2 access solution with active uplinks and redundancy via an inter-switch link between the access layer switches.
Learn what an access switch is, how it works at the network edge, why PoE and port density matter, and how Wi-Fi 7 and IoT change access-layer requirements.
Switch Stacking Expand your access layer with UniFi Enterprise Campus switches. Dedicated 100G QSFP28 stacking ports simplify management, boost reliability, and deliver high-speed links for large
The access layer consists of layer 3 switches, which take routed and switched data packets from the distribution switches and then route them to the access devices in subnets. The access devices in
I often hear it''s advantageous to utilize layer 3 at the access layer devices to avoid having broadcasts spanning the network and not having to deal with huge STP topologies. But what exactly does this
In a large network, we will have different types of switches involved and they play different roles when it comes to the functions. So, we have general guidelines and separate them into
Using this design, you can go up to eight switches and never need more than 4x10-GbE ports per switch to interconnect other access-layer switches or the aggregation layer.
19-inch racks, wall-mount cabinets, open frames with high load capacity and seismic rating.
IP55/IP66 outdoor enclosures with integrated cooling/heating, -40°C to +55°C operation.
Intelligent PDUs with remote monitoring, per-outlet switching, and environmental sensors.
Prefabricated telecom shelters, emergency comms shelters, and network cabinets with cable management.
We provide custom infrastructure solutions, from telecom racks to smart PDUs and outdoor shelters.
From design to deployment, our team ensures reliable, efficient, and scalable power & enclosure systems.
