The Cisco A9K-RSP880-LT-SE is the ASR 9000 Route Switch Processor 880-LT for Service Edge 32G. Specifically, it serves as the system processor for the Cisco ASR 9010, 9006, 9904, 9910, and 9906 routers. As a result, it combines route processing and switch fabric functions in a single module.

32GB Memory for Large-Scale Services

In addition, the -SE version carries 32GB of ECC-protected DRAM, double the 16GB in the packet transport (-TR) version. Consequently, it handles the high memory demands of large routing tables, subscriber services, and complex policies. Moreover, a 4-core 2.4 GHz processor and two 128GB SSDs give it plenty of compute and storage headroom.

Switch Fabric for High-Density Line Cards

Furthermore, the RSP880-LT uses a distributed, multistage, non-blocking fabric architecture. Therefore, it supports high densities of 1G, 10G, and 100G ports across ASR 9000 line cards. Likewise, on the ASR 9910 and 9906, it controls up to seven separate switch fabric cards for additional capacity.

Carrier-Grade Timing and High Availability

The RSP880-LT also supports network timing through BITS, IEEE 1588 PTP, GPS, time of day (ToD), 10 MHz, and 1 pps interfaces. For this reason, it suits mobile backhaul and RAN aggregation networks that need precise synchronization. Finally, operators can run two RSPs in 1+1 redundancy, and Cisco IOS XR supports nonstop routing and hitless software patching.

RSP880-LT-SE vs. RSP880-LT-TR

By comparison, the A9K-RSP880-LT-TR targets packet transport with 16GB of DRAM. However, the -SE version makes the better choice for service edge, BNG, and large-scale L3VPN deployments that need more memory. Note that both RSPs in a redundant pair must be the same type.

Why Lease from Telecom Leasing?

• First, you upgrade ASR 9000 control planes without a large capital outlay.
• Second, we test every unit so it’s ready to deploy.
• In addition, flexible terms cover spares, upgrades, and project builds.
• Finally, you get fast quotes and quick shipping.

Best of all, Telecom Leasing offers the A9K-RSP880-LT-SE for lease or purchase, so you can add RSP capacity or redundancy at a fraction of new cost.

Frequently Asked Questions

What is the Cisco A9K-RSP880-LT-SE?

In short, it’s the ASR 9000 Route Switch Processor 880-LT for Service Edge, with 32GB of DRAM, for the ASR 9010, 9006, 9904, 9910, and 9906.

What’s the difference between the RSP880-LT-SE and RSP880-LT-TR?

The -SE has 32GB of DRAM for service edge scale. In contrast, the -TR has 16GB of DRAM for packet transport roles.

Can I mix an RSP880-LT-SE with a different RSP in one chassis?

No. Instead, both route switch processors in a redundant pair must be the same type.
