FAQs

Q: What is the difference between SE and TR variants?
A: SE (Service Edge) focuses on rich L2/L3 service features and granular QoS for PE/edge roles, while TR (Transport) is optimized for high-scale packet transport with a leaner service set.

Q: Which optics are supported?
A: SFP/SFP+ for 1/10G and QSFP28 for 100G, subject to chassis and software support. Refer to the ASR 9000 optics compatibility matrix for approved part numbers.

Q: Do I need specific fabric cards to achieve 2 Tbps?
A: Yes. Achieving full 2T/slot requires compatible high-capacity fabric modules and an appropriately configured chassis.

Q: Which IOS XR versions are supported?
A: Support varies by chassis and feature set. Check the release notes for your target IOS XR train for exact LC and feature compatibility.

Q: Are advanced features like MPLS VPNs license dependent?
A: Some capabilities require additional licenses and appropriate software images. Verify your feature and license requirements before deployment.
