Q
What is the Cisco ASR 1000 Series Router Module?
A
A Cisco ASR 1000 Series Router Module is a modular line card for the ASR 1000 chassis that delivers high-performance packet forwarding, integrated services, and hardware-accelerated features in a single, hot-swappable form factor.
Q
Which interface modules are compatible with Cisco ASR 1000?
A
Cisco ASR 1000 supports a broad range of modules, including Ethernet (10/100/1000 Mbps, 1/10 Gbps), T1/E1, T3/E3, POS/HDLC, and MPLS aggregation cards designed for high-availability deployments.
Q
How do I install an interface module in the ASR 1000 chassis?
A
Power down the affected slot, slide the module into the front-panel slot until it clicks, secure the module with its captive screws, and then power the slot back on to enable auto-detection.
Q
Are Cisco ASR 1000 router modules hot-swappable?
A
Yes, most Cisco ASR 1000 interface modules are hot-swappable, allowing you to add or replace modules without interrupting chassis operation, provided your software image supports nonstop forwarding.
Q
What is the maximum throughput per module on the ASR 1000?
A
Each ASR 1000 interface module delivers up to 20 Gbps of full-duplex throughput, with aggregate system capacity scaling to 100 Gbps per chassis depending on the platform.
Q
Which Ethernet and TDM interface types does the ASR 1000 support?
A
The ASR 1000 supports Gigabit and 10 Gigabit Ethernet, T1/E1, T3/E3, serial POS/HDLC, and channelized TDM via dedicated multi-service and multi-rate cards.
Q
What SFP, SFP+ and XFP optics are supported on ASR 1000 modules?
A
Certified optics include Cisco SFP (100 Mbps–1 Gbps), SFP+ (10 Gbps) and XFP (10 Gbps) transceivers for single-mode, multi-mode, copper, and DWDM applications.
Q
How can I configure an interface module on the ASR 1000 via CLI?
A
Enter Global Configuration mode, navigate to the interface (e.g., interface TenGigE0/0/0), apply IP addressing or encapsulation commands, and then use ‘no shutdown’ to bring it online.
Q
Can different types of modules be mixed in a single ASR 1000 chassis?
A
Yes, the ASR 1000 chassis supports mixed module installations, enabling you to combine Ethernet, TDM and service modules to meet diverse network requirements.
Q
How do I perform a firmware upgrade on ASR 1000 router modules?
A
Use Cisco IOS-XE Software Upgrade procedures: transfer the new image via TFTP/FTP/USB, install with ‘install add file’ commands, and reload the chassis to activate all modules.
Q
How can I verify the operational status of an installed module?
A
Use the ‘show platform hardware slot <slot> status’ or ‘show platform hardware qfp active r0 counters’ commands to confirm module health, port status, and hardware diagnostics.
Q
What are the power requirements and options for ASR 1000 modules?
A
ASR 1000 supports redundant AC and DC power supplies; each interface module draws up to 100 W, so verify your chassis power budget meets total module requirements.
Q
How do I troubleshoot common interface errors on ASR 1000 modules?
A
Review ‘show interfaces’ for error counters, inspect physical cabling and optics, verify module firmware alignment, and cross-check chassis logs with ‘show logging’ for faults.
Q
Does the ASR 1000 support Quality of Service on its interface modules?
A
Yes, ASR 1000 modules offer hardware-accelerated QoS features including class-based queuing, policing, shaping and congestion avoidance for service-level guarantee.
Q
Where can I find official Cisco documentation and support for ASR 1000 modules?
A
Refer to the Cisco website’s ASR 1000 Series data sheets, configuration guides, and the Cisco Support & Downloads portal for software images, release notes and troubleshooting advisories.
