What was my experience with deployment of the solution?
No issues encountered.
What do I think about the stability of the solution?
It's been very stable since deployment.
What do I think about the scalability of the solution?
It's very scalable, as you just need to buy new modules, and slot them in as and when required.
How are customer service and support?
Customer Service:
Excellent customer service.
Technical Support:I never had an issue yet with this product which required TAC intervention but from my previous experience Cisco TAC support is the best.
Which solution did I use previously and why did I switch?
We previously used 3com switches, and we switched to Cisco in order to standardize our network hardware.
How was the initial setup?
It's easy to deploy if you know what you are doing, and do proper planning. For me, it was pretty straightforward. I have years of experience on Cisco products.
What about the implementation team?
It was an in-house deployment.
What was our ROI?
It's high.
What's my experience with pricing, setup cost, and licensing?
It's worth the price you pay.
Which other solutions did I evaluate?
We considered using Cisco 3700 series switches and stacking them.
What other advice do I have?
It's best for access layer deployment.

Cisco 6509 Ether Switches can be a one stop and do-it-all product for a huge enterprise.
What is most valuable?
The blade module feature which provide the scalability for site expansion.
How has it helped my organization?
A Cisco Network Structure consisted of 3 Layers (Core, Distribution & Access). We used the FWSM (Firewall Services Module) to route the traffic and as a gateway to get to the WAN. As a result, we were able to collapse the Core Layer into the Distribution Layer with a few blade modules (FWSM, SUP & Ethernet).
What needs improvement?
A FoE module would be imminent in the future. This module can communicate with storage devices' and ESXi Servers' HBA (fiber) connection via fibre channel switches (Brocade or Cisco MDS). This can provide a cost effective method in a data center environment without upgrading to a more advanced Cisco Nexus core switch.
For how long have I used the solution?
5 years
What was my experience with deployment of the solution?
The power supply requires certain sockets and UPS (Uninterruptible Power Supply). Each device should require a designated UPS for it. The UPS should not be shared with other devices. An improper termination of the switch's power supply cased a power surge and took out a SUP module during an annual power test.
What do I think about the stability of the solution?
No extraordinary issues. Just minor day-to-day issues.
What do I think about the scalability of the solution?
The Chassis can run out of slots as the environment expand further along.
How are customer service and technical support?
Customer Service: Great but Cisco outsources its customer support services to India since most of our issues and outages occurred after hours. Some support technicians have a heavy Indian accent which led to difficult comprehension and time consumption.Technical Support: 4.5 out of a 5 since Tech Support personnels are very knowledgeable of the product.
Which solution did I use previously and why did I switch?
No, I have not due to our contract agreement with Cisco.
How was the initial setup?
The initial setup consist of the right personnel to set up and administer the product.
What about the implementation team?
All implementation were completed by in-house team members.
What was our ROI?
Centralized administration and reduced time consumption.
What's my experience with pricing, setup cost, and licensing?
The SUP (Supervisor) module can provide up to 720 GBPS of data transmission compared to a stackable Cisco 3750 switches.
Which other solutions did I evaluate?
Yes, the Cisco Nexus 7000 Series core switches.
What other advice do I have?
No further comments.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Consulting Engineer EMEA at a computer software company with 201-500 employees
Remote management and monitoring, multi-layer switching and flexibility are valuable features.
What is most valuable?
Remote management and monitoring, multi-layer switching, flexibility, per port configurations, possibility of port aggregation, standard management interface, loads of documentation available from Cisco and Partners, multitude of troubleshooting tools embedded in the OS, QoS.
How has it helped my organization?
Ease of deployment of internal networks, separation of departments traffic, replacement of hubs (and the respective absence of collision related network unavailability), implementation of VoIP, improved configuration and access management.
What needs improvement?
VTP should be configured as Transparent by default.
For how long have I used the solution?
Several years, on different projects.
What was my experience with deployment of the solution?
A close look at each part-number characteristics is recommended, especially regarding the type of Uplink Ports (do you need fiber or copper uplinks for example?) and specific protocols (do you need BGP? is RIPv2 enough, for instance), as some of them are only available in specific models or with additional licenses. Selecting the licensing type can be the slightly tricky part, although you can usually upgrade it later.
What do I think about the stability of the solution?
Not unless it was caused by malfunction or a mixup in configuration.
What do I think about the scalability of the solution?
On the specific cases I used, never. Adding new switches to the networks is painless (but please be careful with the VTP configuration though, as if it’s not configured you do have the possibility of a new switch giving you trouble with the VLAN configuration).
How are customer service and technical support?
Customer Service: Excellent.Technical Support: Besides the great set of documentation available, partner support is usually good, no issues so far, on different projects.
Which solution did I use previously and why did I switch?
Previous configuration was based on a basic router and switch configuration for each separate network, interconnecting at router level. The needs included reducing equipments, add management to the network to allow central monitoring and configuration, and adding new functionalities to the network, as well as having a buildup of different networks to separate traffic.
How was the initial setup?
Straightforward if you’re installing for the first time. If it’s not the first installation, and you have multiple VLANs in place, be careful with the VTP configuration setup, as a misconfigured switch, since it’s on VTP server mode, can give you trouble.
What about the implementation team?
Mixed types of implementations. Mixed expertise levels - some partners have better technicians than others, but never had a case where the technician didn’t leave with the configuration completed.
What was our ROI?
Generally a reduction on the number of equipments to manage, less time to manage and higher uptime.
What's my experience with pricing, setup cost, and licensing?
Day to day costs are the maintenance costs from the manufacturer (different levels available), and part of the time of the IT Team. Setup Costs have depended on projects, and specific setup needs.
Which other solutions did I evaluate?
A few, namely Huawei and HP. While Huawei did allow some of the same characteristics at a lower price, available expertise and documentation, tipped the balance to Cisco, and the greater flexibility and feature set tipped the balance from HP.
What other advice do I have?
Check that it’s the most cost effective solution (it’s very expensive if you only want to connect 4 users and a printer.); Check the model that fits your needs, regarding number of ports, and PoE for instance (no need of PoE for most uses.); Main uses would be to use a solution with multiple internal VLANs (needs at least IP Base License), VoIP implementations, and adding security and manageability to the network; Carefully check what License Feature set you need (there are 3 levels, LAN Base, IP Base, and IP Services), depending on your needs. You may be able to upgrade the software feature set later, but should check ahead.

Pro's and Con's of transitioning from Juniper to Cisco
I recently spoke with a colleague who transitioned from Juniper to Cisco. We agreed that each solutions is completely different and each one has its strong and weak points.
The transition process was rather hard. It was hard to change approach and rare similarities were sometimes misleading for my colleague. Although Cisco is moving away from the standard monolithic IOS straight to modular architecture there are many disadvantages for somebody who 'thinks modular'.
Personally I have experience with Cisco and although I have some difficulties and a Cisco-centric way of thinking, I prefer it over the others. But if I would possibility need to be involved in a Juniper environment, I think it would be worth to walk through the transition process.

In my experience, the cisco devices do handle extremes quite well, I've worked with millitary deployable kit thats dropped off trucks or out of aircraft, or in mine sites with unstable power and numerous other nasties. The biggest issue with these kinds of environments is dust and extreme temperatures, or in the outback the bull dust, being sucked through the machines, not an issue until moisture is also incurred. All vendor network devices will suffer under those forms of conditions, but the Cisco kit still seems to keep ticking even with that sort of harsh treatment. Can't say what the Cisco RMA returns engineers would think on opening up a returned device thats full of bulldust though, I'd assume that might void the warranty :-).
