Cisco Intelligent Traffic Director (ITD) is a zero latency multi-terabit layer 4 load-balancer available on 5k/6k/7k/9k. It has support for traffic steering and clustering solution on the Nexus series of switches.
ITD allows customers to deploy servers and appliances from any vendor with no network or topology changes. With a few simple configuration steps on a Cisco Nexus switches, customers can create an appliance or server cluster and deploy multiple devices to scale service capacity with ease. The servers or appliances do not have to be directly connected to the Cisco Nexus switch. ITD takes load balancing decision in a single clock cycle of the switching hardware, Hence avoiding latency altogether.
ITD 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 provides order of magnitude CAPEX and OPEX savings for the customers. ITD is available on Nexus 7000/7700 series in NX-OS 6.2(10) or later. It is available for demo/EFT on Nexus 5k/6k/9k. ITD is much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.
Note:- ITD is not a replacement for L7 load balancers
Hello Avni Baveja,
You are mentioning 5K/6K/9K for Demo purposes. How can we get more info on that?

Hi Michel, Please send me an email on ask-itd@external.cisco.com, I can give you demo and further details
Thanks

This is a great news! I love the ability to rely on wire-speed for L3/L4 LB in order to stack as many L7 LBs as needed to address specific needs. Glad to see you again in this market segment, Cisco! Welcome back!
Afer Cisco stop support SLB feature on C6500 in the newest version of IOS we finally get these really needed feature on Nexus swithes.that is great and can save too much money for smaller shops that don’t need L7 LB.as i see the most enterpise networks and Datacenters need only L3-L4 LB and don’t need fancy , pricy , poor performance L7 LB.thanks Cisco
