Cisco 9000 Series Aggregation Services Routers (ASR 9000)

Any large enterprise with large throughput requirements for their business-critical infrastructure should use the ASR series routers without exception. The licensing cost might hit your pocket hard, but with the exceptional performance and reliability that the ASR series offers, it is easily the best option available in the market. It is the "tried and tested" router. Don't think twice, just go for it!

Cisco Nexus

Cisco Nexus switches are designed for data center environments or other environments that require high bandwidth switching. This includes mainly server connections with many virtual machines residing on them, fabric channel of ethernet[,] or something similar. Nexus is not suited for user switches, WAN switches, or other switches that don't need a lot of processing power.

Pros

Cisco 9000 Series Aggregation Services Routers (ASR 9000)

  • 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.

  • These switches are easily programmable. If you are looking at SDN but aren't quite there yet, this switch line is a great starting point. They support DevOps tools, which make automation extremely quick and efficient.
  • There are so many options in this product line, making Nexus a great switch for pretty much any deployment. You can stack switches or use the modular switch, whatever fits your need.
  • These switches support VXLAN, allowing for a multi-tenant network environment, and is perfect for cloud services.

Cons

Cisco 9000 Series Aggregation Services Routers (ASR 9000)

  • 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.

Cisco Nexus

  • If you are on the wrong code it can be buggy
  • When deploying, one switch was bricked (dead) during an upgrade of the NX-OS, and had to be replaced
  • If you are not familiar with NX-OS it can be difficult to configure
  • They lack some of the functionality that the Nexus 9k has

In our environment (and especially during COVID and the Work From Home era), I would really like our network devices to be more resilient [against} errors in remote configuration. Having a standard, easy to use, configure, commit/deploy, rollback system should be installed, but it's not there. Other companies have been providing this for over 20 years, and Cisco does this on some of their devices. Why not all?

These switches are very fast. They've been designed to work within the data center. We connect them to Cisco UCS-B Mini servers with the storage being directly attached. They are able to handle the data traffic pretty easily. We can also move servers pretty fast from data center to data center without overloading them. This has allowed our company to stay running during any kind of conditional outage. We have come to really rely on them for business continuity.

In some ways, the platform is a big improvement over our previous IOS and NX-OS devices:
  • They offer version-controlled configuration staging/commits.
  • They have a robust portfolio of network protocols and features even beyond datacenter devices.
  • Due to the use of NPUs instead of relying entirely on ASICs for forwarding, new versions of the software are able to improve hardware performance and capacity.
Unfortunately, I have run into more bugs on IOS-XR than I ever did on IOS or even NX-OS (which has a shocking number of bugs of its own) and you have to be a licensing guru to get your order right the first time.

I've said it before and I'll say it again: Cisco support is really good at being quick with their replies until they discover it's not a "network-down emergency." They start by immediately responding to your e-mails & inquiries, and the minute they discover that it's not a huge deal the tech-support employee "goes on vacation," defers you to someone else, and that person immediately takes three days to answer any e-mails... and then he just asks for different outputs.

Alternatives Considered

Cisco 9000 Series Aggregation Services Routers (ASR 9000)

Each has its own strengths and weaknesses. Juniper was more security/less routing and Cisco was more routing/less security. Redback was Ericsson which is easy when creating VRFs known as contexts. When doing show command it would give you all the information within that context. In Cisco you need to perform 3 or more commands to get the same info.

Extreme is an excellent edge networking device. We have not evaluated Cisco Nexus core networking versus Extreme for core networking yet. We expect to compare them soon. However, at this time, we have not had the need to try and replace the Cisco Nexus because of it's incredible reliability. I expect Cisco Nexus to stand up well to comparison.

The Nexus 3000 series switches are data center switches, so I would say they have similar security ability to other switches in this segment. I don't have a lot of experience doing more than basic ACL security on switches, but I know these can be integrated into other security solutions like Cisco ISE and 802.1x authentication. It could also be integrated into an ACI solution to add micro segmentation, which would bring in other security functions.

Return on Investment

Cisco 9000 Series Aggregation Services Routers (ASR 9000)

  • 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.

  • We have been very successful with network uptime
  • It's has always met our future needs to date when adding new data center hardware
  • We have had these for almost 5 years and it still has support available to ensure maximum ROI before we need to regreen it
