Cisco 9000 Series Aggregation Services Routers (ASR 9000) vs Huawei Ethernet Switches

• Layer 3 multicast. It handles the additional load of multicast without issues. Other platforms we have used have had over-subscription issues.
• We've used several MPLS features such as pseudowire using bridge-domains as well as xconnects. Plenty of features to solve any design problem.
• IOS XR. I just love operating in IOS XR. Solve so many problems that exist in IOS.

• There is little to no bandwith loss
• Power-over-ethernet is a welcome feature
• VLANs can be configures easily

• Upgrade process overly complicated compared to NX-OS or IOS: new images and the current configuration need to be compiled into "golden IOS's". If you don't include the configuration, you will have a clean device with no config.
• Major bugs in every release. We have had to cycle through all of our routers 3 times in the last year for updates due to show-stopping bugs that did not come to light until after the changes were made in production.
• Terrible documentation. You have to mine their site to get to any documentation for recent versions of IOS-XR. If you make the leap from 32-bit cXR to 64-bit eXR then the documentation is more-or-less non-existent. Due to the internal architecture of hardware itself, technical specs can change from software version to software version, so don't expect any sort of firm scalability numbers. You'll have to rely on your sales engineer for that.

• The cost of the hardware is acceptable but the licenses of use are expensive and in the end its price equals or exceeds the switch of other brands.
• There are functionalities that should be available in the standard version and when they are trying to enable, Huawei support indicates that they have an additional cost which causes inconvenience and difficulties at the time of implementation
• the performance of the equipment is inferior to those of other brands although it is decent.

• Higher reliability has significantly reduced the need for manual intervention
• Lower downtime ensures better top-line figures
• Although it may be difficult to quantify, I am certain that the higher performance does have an impact (maybe indirectly) on other business functions. High-performance routers are like the oil that keeps an engine running smoothly.

• For basic and standard functionalities is a viable and relatively cheap option.
• It is not advisable to use it in high-profile projects, it is preferable to use Cisco switches.
