  • 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

  • They handle are large number of IPSec tunnels.
  • They run the nearly-universal IOS-XE, so they're easy to support.
  • They have a decent amount of connectivity options, especially when you include add-in cards.
  • With the rapid growth in bandwidth requirements, their maximum throughput will be their limiting factor.
  • There are too many concurrent IOS-XE trains available.
  • We've had to upgrade code more frequently than we did with our ISR 3925 routers.

  • Excellent throughout
  • Enough interfaces to cover our needs
  • No outages
  • Currently is working as expected
  • No issues
  • We saw an issue a long time ago (but on a provider router) where two different versions of NetFlow were not supported, it turned out to be a bug issue.
