Extreme Networks 5120-24X-4Y - 10G/25G Aggregation Switch
Overview :
The 5120-24X-4Y is a stackable enterprise aggregation switch from Extreme Networks' 5120 Universal Switching series. It is designed for high-throughput campus and data center edge aggregation, supporting mixed 10G and 25G workloads.
It provides 24 ports of high-speed Ethernet (10G/25G capable depending on model variant) and 4 uplink ports for 25G SFP28 connectivity, making it suitable for spine-leaf or collapsed core designs.
Typical deployments include:
- Campus aggregation layers
- Data center Top-of-Rack (ToR) aggregation
- High-density enterprise backbone networks
- Secure segmented VLAN environments with MACsec support
The switch supports Extreme Platform ONE / ExtremeCloud IQ management, enabling centralized automation, ZTP provisioning, and policy-based security enforcement.
Not suitable for:
- Small office networks (overbuilt and high power footprint)
- Non-managed or standalone environments without controller/cloud
Key Features :
- 24-port high-speed 10G/25G-capable access switching fabric
- 4× 25G SFP28 uplinks for high-bandwidth aggregation
- Stackable architecture supporting up to 8 switches
- MACsec encryption for secure layer-2 traffic protection
- Cloud-managed via ExtremeCloud IQ or Platform ONE
