Q
What reliability features ensure uptime on the ASR 1000?
A
Reliability is ensured by modular, hot-swappable components, redundant power and route processors, NSF/SSO, and hardware watchdog timers to automatically recover from failures.
Q
How can I troubleshoot common issues on the ASR 1000?
A
Troubleshoot using built-in diagnostics like Cisco IOS XE Embedded Event Manager (EEM), show and debug commands, syslog, real-time telemetry, and onboard packet capture for root-cause analysis.
Q
What are the typical use cases for the ASR 1000 Series?
A
Common use cases include enterprise WAN aggregation, secure Internet edge, data center interconnect, service provider broadband aggregation, and cloud on-ramp services.
Q
Where can I find technical support and documentation for the ASR 1000?
