Key learnings from peers

Valuable Features

  • "Technical support is very good, especially when you compare it to other vendors we have here."
  • "Overall, ExtremeRouting requires less technical depth in order to implement the infrastructure than Cisco, for example."
  • "We evaluated Cisco routers as well, but we chose ExtremeRouting because it was more user-friendly, budget-friendly, cheap compared to Cisco, and has an easy configuration process."

Room for Improvement

  • "We are concerned with how the solution will evolve to the next generation of Contact Center. It's not evolving as quickly as we would like it to."
  • "My advice for those looking into ExtremeRouting is: right now all switch manufacturers are backed up for months."
  • "We have not had a very good experience with customer service and support."

Pricing

ExtremeRouting pricing is considered comparable to other solutions, with minimal standard licensing costs but additional fees for specific features like 10 GB licenses on lower-end models. Technical support incurs extra charges. Some users indicated uncertainty about licensing costs. An average premises switch may cost around $500 annually with the management license.
  • "We have no issues with the price."

Service and Support

Customer service for ExtremeRouting receives mixed feedback. Some report satisfaction, especially with third-party support from a Montreal provider, noting additional expenses for their service. Others highlight issues with slower response times and varying technical expertise. After transitions from Nortel to Avaya, some experienced technical difficulties, though improvements are noted under Extreme Networks' management. Satisfaction levels vary, with ratings ranging from six to four out of ten.

Stability

ExtremeRouting exhibits mixed stability. Some users encounter significant issues with components and lack trust, leading to replacement decisions. Others find the device very stable with minimal reboots and note a challenge with interoperability between Extreme fiber interfaces and Cisco components. Stability concerns are sometimes attributed to the software, with a rating of six and a half out of ten by some users.

ExtremeRouting Reviews Summary
Author infoRatingReview Summary
Senior Solutions Specialist at a comms service provider with 201-500 employees3.5My company uses ExtremeRouting in a large LAN environment to manage ERS switches and core switches efficiently. While the hardware is excellent, I believe improvements are needed in support, software resiliency, and stability compared to earlier offerings.
Chief Information Security Officer at a healthcare company with 51-200 employees4.5I value ExtremeRouting's FabricOS for virtualizing our network, its easy setup, and solid stability for up to 10,000 users. It's cost-effective compared to competitors. However, current supply chain delays are a concern for quick implementation.
Owner at Prb technology systems4.0I primarily use ExtremeRouting in office and educational settings to enhance processes and network management. Its performance is impressive, but more comprehensive training is necessary for effective use. Previously, we used Avaya, and our cloud service is Microsoft Azure.
Assistant Manager-Networks at a university with 1,001-5,000 employees4.0I use this solution for extreme routing, valuing its stable stacking for redundancy. It's user-friendly and budget-friendly. However, it lacks the latest protocols, causing compatibility issues with other vendors, and customer support is poor.
Engineering infrastructure manager at a financial services firm with 10,001+ employees3.5I find ExtremeRouting stable, scalable, and easy to set up with good support. My main concern is its slow evolution and readiness for next-gen Contact Center solutions, which is a significant issue.
Conseiller en architecture technologique at a government with 1-10 employees3.5While its routing protocol is valuable, I've found this solution unstable, unreliable, and plagued by faulty components. My overall experience was very bad, prompting replacement, and I advise against its purchase.
