​​ASR-920-24SZ-M++ Overview: Core Architecture​​

The ​​ASR-920-24SZ-M++​​ is a ​​24-port, multi-service aggregation router​​ within Cisco’s ASR 920 Series, designed for ​​carrier Ethernet and high-density metro networks​​. It features ​​24x1G/10G SFP+ slots​​ with MACsec encryption support, housed in a ​​1RU form factor​​, making it ideal for space-constrained environments requiring scalability and security.

​​Technical Advantages for Service Providers​​

• ​​Flexible Speed Configuration​​: Ports auto-negotiate between ​​1G and 10G speeds​​ to accommodate legacy and modern fiber links.
• ​​Enhanced Throughput​​: Delivers ​​240Gbps system capacity​​, ensuring non-blocking performance for high-traffic aggregation.
• ​​Power Efficiency​​: Operates at ​​<200W​​ under full load, reducing cooling costs in densely populated racks.

​​Target Applications and Use Cases​​

• ​​5G Mobile Backhaul​​: Supports precise timing via ​​PTP (IEEE 1588-2008)​​ and ​​SyncE​​ for low-latency fronthaul/backhaul.
• ​​Metro Ethernet Services​​: Enables E-LINE, E-LAN, and E-TREE topologies with MPLS and VPLS integration.
• ​​Cloud Gateway Aggregation​​: Manages traffic between data centers and public cloud platforms with ​​VXLAN and EVPN​​.

​​Resolving Key Deployment Questions​​

​​Q: How does the “M++” differ from the standard ASR-920-24SZ-M?​​

The M++ variant includes ​​pre-licensed advanced features​​ like MACsec and Segment Routing, eliminating the need for separate license purchases.

​​Q: Is it compatible with third-party SFPs?​​

While Cisco recommends using validated optics, the router supports ​​third-party SFPs​​ with limitations—some advanced diagnostics may be unavailable.
