  • Pay as you grow - Increase the backbone bandwidth as per your enterprise requirement. So single box can support multiple variants of offices.
  • Space consolidation and improved TCO - Total cost of ownership as single converged device able to support branch and enterprise platform, simple to provision, manage, maintain, troubleshoot and monitor. support encryption, UC, WAN optimization and performance management tools.
  • Business continuity and resilience - ISR models support dual integrated power supplies, with ability to support PoE power to endpoint. Modular network interface. Supports Cisco Unified survivable remote site telephony (SRST), which serves as resiliency to Cisco UC Collaboration solution.
  • Lower WAN expenses - integrated and embedded SDWAN solution for enabling low cost internet solutions.
  • There are different variants of licenses to boost performance. Boost and performance licenses. Perf license is cheaper than boost. And different for varying bandwidth requirements. This does create confusion at times, explaining to management. This is a room to simplify here.
  • User interface GUI capable would be a great asset for this product along with command line capability.
  • Cost of devices can be made more competitive. Currently this is priced on higher side compared to 8xxx series routers.

  • It's working well in routing as long as we know the performance, we know the neighbor, we know how many routing table we need to do. It's working well. We don't have to touch anything. Yes, it stays there. If we don't do anything, it stays there for so long.
  • Actually it's good already, but sometimes users ask me why this product doesn't have an interface that other products have. But in term of technical, they don't care. They're just doing command line, and yes it's working well, but if they come both for interface and command line in the sandbox, don't need to integrate with other appliance

  • First of all, I would say that they're very efficient in terms of having end-to-end connectivity and also uptime. It's all time. We never had any issues dropping links and things like that. So provided you have a good bandwidth and a good backend, this device just works. We never touch them. It's brilliant. And the routing we use as well, the PBI OSP or BGP works really nicely with the underlying iOS version as well. So I think from the reliability perspective that's why we trust the brand. It works really well.
  • I would say that it's for the reason we are migrating now, that every product you have to replace every three to five years. You have to have a roadmap to move in. The reason is business is changing so the product you had seven years ago may not align with cybersecurity or could be with scalability and also redundancy and other stuff. But if I can focus on this particular brand, the problem we have is bandwidth. It can only support after a hundred meg. The one we have for 300 and now we are going into a one-gig backbone. So that's why we are trying to move into a new technology and also some enhancements from cybersecurity as well. So those are the key reasons from a performance perspective as well as from the cybersecurity perspective we would like to move as well. And we're also changing dynamically from the business side of it, we need to meet their requirements as well from all the cyber stuff. So those are the key points I would say mainly from a bandwidth perspective and from cybersecurity as well.

  • Easy to program.
  • There's just a limitation on the amount of modules that we could put on. And then if you want to put a little more, then you have to pay a lot of money just to get a bigger chassis. I mean, the price, I think that's the main issue is the price jump from like a smaller bay to a bigger bay is like a huge amount of money on that.

  • One of the things I like is because I'm in operations, I deal with software upgrades. So some of the other products take a while after you reboot them or upgrade them to come back up. What I like about these ISRs, is that they reboot really quickly, come up, and are back providing that connectivity quickly. So our downtime is minimal, which I appreciate.
  • I was just trying to think of any room for improvement. It's hard. It does a lot. It does what we need. It does the operations, I can't think of anything for improvement actually

  • The ISR 4000 is an excellent router for our voice services. We purchased CUBE licensing in order to do this.
  • The ISR 4000 is an excellent router for security purposes as well. We purchased the security license with the router and that allowed us to run a Zone-Based Firewall.
  • The ISR 4000 is very simple and straight forward to configure.
  • Licensing the router using Cisco Smart Licensing can be troublesome especially if the router is in an air-gapped environment.
  • It would be nice if the router came standard with more onboard ports

  • Excellent internet connectivity, excellent security, storage, and the ability to be upgraded are all provided by this device.
  • Applications and advanced encryption methods are used to simplify operations and management while also automating some aspects of it.
  • Current IPSec encryption support offers gigabit ethernet connectivity along with high-speed data transfer rates.
  • A greater number of onboard WAN ports would be an improvement over the model we purchased, which only had two. [This] means we'll have to buy more expensive network cards to get more convenience.
  • The small router was a plus in some branches, but it was a hindrance in others. Its width is about half the size of the rack, so we had to keep it on top of another device.
  • When compared to its competitors, the rack mounting kit is unreliable and expensive to purchase.

  • DMVPN
  • QOS for VOIP
  • LTE backup Internet services
  • Internal virtualized VMware services (AD, print, domain, file and other VM services)
  • Voice/SIP trunking services
  • Excellent DR networking capabilities
  • MPLS trunking services
  • The UCS-E blades that you can insert into the routers only get refreshed every 4-5 years. So the cpu/memory/HDD options are limited and quite dated
  • Some LTE connectivity options for some countries are lacking or LTE NIM cards for some countries are not supported
  • Does not support dual power supply options for maintaining uptime from power events

  • THE fastest routers I've had the pleasure of working on!
  • Tons of connectivity options available on these bad boys
  • Hands down some of the best tech support in the world
  • Super expensive to purchase and maintain licensing for
  • Even with a big player like Cisco you get bugs in the software but hey, at least they're quick to fix them
  • Sometimes you do feel like guinea pigs testing out beta software

  • Easy to set up and nicely designed GUI
  • Huge scalability factor
  • Very secure platform with many bug patches regularly
  • Many features that other vendors are missing or that they'd make you pay to include
  • More frequent software updates/patches
  • Easier patch management and installation
  • Integration with Cisco Smart Licensing could help
  • A faster boot from cold start would be great

  • Modular design allows for lots of expansion options
  • The voice module gives us full control over all our VOIP systems
  • The system integrates well with our Cisco management and monitoring tools
  • Third-party monitoring options can't get as much data from these boxes
  • CDP protocol is still mostly a proprietary protocol
  • Among the most costly integrated routers out there

  • A big strength of Cisco in general is their support team
  • These boxes are very stable and do not require a ton of patches after deployment
  • Pretty easy setup if you're already familiar to cisco command line
  • Web interface is fairly lacking for new users
  • Some newer protocols are not support as of yet
  • Still priced towards the top of the pack
  • Could use more rack mount options and rail sizes

  • It's a great product which does data routing and it is used for Voice infrastructure too
  • In branches where minimum capacity is required then this can be used as an independent PBX with dialing capability.
  • SIP trunks can be easily terminated on this router which is quick and not much efforts to get it working.
  • It also works as a survivable PBX in remote branches in case of WAN failure.
  • SRST feature which allows survivability in branches should have all the featured we get in sunny day on main system.
  • with C1 and foundation license removed the DNA license should have Basic option too to provide same earlier features to add separately.
  • Router should be provided with NIM slots to add FXS/FXO modules
