Introduction to the A99-48X10GE-1G-TR=
The Cisco A99-48X10GE-1G-TR= is a specialized switching module designed for high-density, multi-service environments. It provides 48 x 10 Gigabit Ethernet (10GE) ports and a dedicated 1 Gigabit Transport (1G-TR) interface, catering to networks requiring simultaneous data transport and traffic prioritization.
Technical Breakdown and Core Capabilities
- High-Speed Port Density: Optimized for spine-leaf topologies, the 48 SFP+ ports support 10GE for server farms or aggregation layers.
- Transport Interface: The 1G-TR port enables MPLS-TP or metro Ethernet transport protocols, ideal for service providers or enterprises with WAN extensions.
- Advanced QoS: Hardware-based traffic shaping and priority queuing ensure low jitter for voice/video applications.
- Chassis Compatibility: Integrates with Cisco Catalyst 6500/6800 series switches running Cisco IOS-XE 3.6E or later.
Key User Questions Answered
1. What distinguishes the “TR” designation in this module?
The 1G-TR interface is engineered for transport-oriented networks, supporting legacy protocols like TDM pseudowire or modern Carrier Ethernet standards. This makes the module versatile for hybrid WAN scenarios.
2. Can it handle both enterprise and service provider workloads?
Yes. The A99-48X10GE-1G-TR= balances enterprise Layer 3 routing (OSPF, EIGRP) with transport-layer features (MPLS, QoS), making it suitable for multi-tenant data centers or telecom edge deployments.
3. Are there licensing limitations for advanced features?
Cisco’s Transport Services License is typically required for MPLS or pseudowire functionality. Ensure your chassis supports Software-Defined Access (SDA) if integrating with intent-based networking workflows.

Final Perspective
The A99-48X10GE-1G-TR= fills a niche for organizations bridging enterprise and carrier networks. While its transport capabilities are robust, the reliance on older Catalyst platforms may deter users seeking cloud-native automation. For existing Catalyst 6500/6800 users, however, it’s a pragmatic choice—especially when modernizing legacy WAN links without overhauling core infrastructure. New deployments, though, should weigh it against Cisco’s newer NCS 5500 series for long-term scalability.
