Last week, I went through application assurance with Cisco Prime Infrastructure. Today, as the 4th post of a 5-part blog series, I’ll go into troubleshooting for your branch site with Prime. Again, as a quick recap, here’s my blog series on how to set up networking with Prime for a new branch site.
By now, your new branch site is in perfect condition with Cisco IWAN, wired and wireless Converged Access, as well as application assurance all working as designed. But you need to be prepared to start troubleshooting if something goes wrong. Every user who runs into network issues means productivity loss. Every minute of a down network causes a significant amount of business loss. Fortunately, Cisco Prime Infrastructure gives you many tools, so you can achieve speedy problem resolution and provide outstanding user experience.
Here’s a Prime troubleshooting success story that a customer told me. It’s a hospital in Dallas, Texas. Keeping their wireless network running was a critical business priority because the medical staff depended on it for communications and patient care. One day, nurses reported intermittent wireless problems in a room. You know, intermittent problems can be hard to troubleshoot. When you are ready to diagnose the problem, the symptoms may or may not exist anymore. Using Prime, their networking team was able to narrow down to a laptop which was always present when the wireless problems occurred. As it turned out, it was doing heavy and unauthorized live streaming which hogged the wireless bandwidth. The owner was immediately notified to stop streaming. Problem solved and case closed.

ITD (Intelligent Traffic Director) has been selected in Top 3 finalists in the Best of Interop 2015 Data Center category. ITD Delivers:
- $2 Billion TAM disruptive technology: This technology innovation disrupts today’s $2 Billion TAM for load-balancers, redirection and clustering solutions
- 100x Scale improvement: The high-end load-balancers today can handle about 200Gbps traffic. ITD can load-balance 20Tbps traffic.
- 1000x cost-savings for customers: A 40Gbps L4 load-balancer costs about $200k to customers. ITD provides multi-Tbps load-balancing for a fraction of the price.
- Zero Latency: ITD performs load-balancing, redirection, NAT and access control, all in one-clock cycle in hardware, hence it introduces zero latency.
- 10x OPEX savings : Order of magnitude reduction in configuration, and ease of deployment
- Overall CAPEX savings : Wiring, Power, Rackspace and Cost savings
- 70+ customers interested in deploying within 1 month of shipping.
- 10x High availability : N + M redundancy, health-monitoring and automatic failure handling
- $15 Billion install-base can be leveraged: The technology has humongous market capture potential. It works on existing hardware. $15 Billion install-base of Nexus switches is able to use this technology.
- 30+ patentable ideas: ITD has unprecedented innovations.
Cisco ITD (Intelligent Traffic Director) is a hardware based multi-Tbps Layer 4 load balancing, traffic steering and clustering solution on Nexus 9K/7K/6K/5K series of switches. It supports IP-stickiness, resiliency, NAT, (EFT), VIP, health monitoring, sophisticated failure handling policies, N+M redundancy, IPv4, IPv6, VRF, weighted load-balancing, bi-directional flow-coherency, and IPSLA probes including DNS. There is no service module or external appliance needed.
ITD has a lot of different types of use-cases. Some of these are:
- Create a multi-Tbps Firewall
- Create a multi-Tbps Video-cache
- Firewall/IPS/IDS/WAF load-balancing.
- Web Server load-balancing
- Application server load-balancing
- Replace WCCP. Redirect and Load-balancing traffic to Web-cache, WAAS, WAE
- Traffic steering to VDS/video-cache/Professional Media Network devices
- Load-balance to Hadoop/Big-data cluster.
- load-balancing to mobile equipment
- Load-balancing to Layer 7 load-balancers
- Replace legacy features such as ECMP, port-channel, PBR, etc

Transforming Cisco switches into highly scalable zero latency load balancers! Cisco Intelligent Traffic Director (ITD) does exactly that and much more!
Cisco ITD has been selected as Best of Interop 2015 finalist in the Data Center Category. Finalists were chosen from nine categories including Data Center, Mobility, SDN and Cloud Technologies.
Cisco Intelligent Traffic Director (ITD) is an innovative solution to bridge the performance gap between a multi-terabit switch and gigabit servers and appliances. It is a hardware based multi-terabit layer 4 load-balancing, traffic steering and clustering solution on the Nexus 9K,7K,6K,5K series of switches. Customers do not have to buy any new hardware. It works on all the existing hardware, linecards and supervisors.
Here are some of the quotes from customers, account teams, industry analysts and architects:
“Great milestone Samar Sharma, Mouli Vytla, Rajendra Kumar Thirumurthi and team! We are very grateful for the work you guys did with pioneering and driving this new solution!”
“ITD helped us scale to 1Tbps of cache traffic in single Nexus 7700 ”
“This feature seems almost too good to be true! I am very excited about it.”
“Customers really enjoyed the time and the subject. They said it was the best presentation of the week at Cisco Live”
“Turns out we likely have a far superior solution in ITD that we can bring to the table. One of our web space principles is ‘state is the enemy of scale’ and ITD aligns very well with this mentality without sacrificing too much flexibility or control. It is still early in our conversations but we are confident that ITD will play a strategic role for scaling services”

is an innovative architecture that logically integrates an external service appliance such as Citrix NetScaler or the Cisco Prime NAM
so that it appears & operates as a service module within the Nexus 7000 Series
RISE integration with the Citrix NetScaler provides features like Route Health Injection (RHI) and Automated PBR (APBR) which allow easy configuration to redirect client and server traffic to the load balancer.
Automated Policy Based Routing (APBR)
Existing solutions to have server traffic return to the load balancer are Source NAT and PBR. Using Source NAT causes applications (server) to lose the visibility to client IP, burning IP address pool for Source NAT configuration and manual configuration. Policy Based Routing (PBR) requires complex initial configuration from the user (susceptible to human errors), configuration updates when a server is added or removed which can be cumbersome as the number of network devices and servers/VIPs grow.

Data Centers are becoming increasingly smart, intelligent and elastic. With the advancement in cloud and virtualization technologies, customers demand dynamic workload management, efficient and optimal use of their resources. In addition the configuration and administration of Data Center solutions is complex and is going to become increasingly so.
With these requirements and architectures in mind we have a industry first solution called Remote Integrated Service Engine (RISE). RISE is a technology that simplifies provisioning, out of box management of service appliances like load balancers, firewalls, network analysis modules. It makes data center and campus networks dynamic, flexible, easy to configure and maintain.
RISE can dynamically provision network resources for any type of service appliance (physical and virtual form factors). External appliances can now operate as integrated service modules with Nexus Series of switches without burning a slot in a switch . This technology provides robust application delivery capabilities that accelerate the application performance manifold.
RISE is supported on all Nexus Series switches with services like Citrix NetScaler MPX, VPX, SDX and Cisco Prime NAM with many more in the pipeline.
