ASR1000-ESP20 Overview
A twenty-gigabit module for centralized forwarding
ASR1000-ESP20 is the Cisco ASR 1000 Series 20-Gbps Embedded Services Processor. The hardware comparison identifies 1 GB of QuantumFlow Processor memory, 256 MB packet buffering and 4 GB FECP DRAM. These are module resources, not a description of a fully populated router or the memory of every component in the chassis.
Interface capacity comes from the rest of the system
There are no front-panel traffic interfaces on the ESP module. Match the host chassis, route processor and interface-adapter population separately before planning a replacement. Cisco warns against operating different ESP models together in one chassis except during an upgrade; follow the supported upgrade procedure for the exact system.
Treat forwarding and application results as different checks
The 20-Gbps designation is the processor bandwidth class. It does not establish a guaranteed encrypted-traffic rate or an application benchmark for every packet size and enabled feature. Record the real workload and verify the complete hardware and software combination before assuming that a faster ESP alone removes a deployment bottleneck.
Use the ESP20 retirement notice, not the ESP10 dates
Cisco c51-740476 explicitly covers ASR1000-ESP20. Its sales cutoff was March 26, 2019 and the final support date was March 31, 2024; IOS XE 16.12 is identified as the last supported release. Review migration and recovery requirements because purchasing a spare does not reinstate manufacturer support.
