Abstract: Embodiments of the present disclosure enable monitoring network traffic on multiple Virtual Device Context (VDC) elements of a switch using a single NAM module. To that end, if a monitored network element supports contexts (i.e. VDC elements), a NAM module could be configured to seamlessly drive the move of the data port interfaces (at the managed device) from one context to the other. After the move of the data ports that support SPAN destination traffic flow to the target VDC is complete, these SPAN destination ports may be configured to be able to receive SPAN data traffic.

Abstract translation: 本公开的实施例使得能够使用单个NAM模块监视交换机的多个虚拟设备上下文（VDC）元件上的网络业务。 为此，如果受监视的网络元件支持上下文（即VDC元素），则NAM模块可以被配置为无缝地驱动数据端口接口（在被管理设备处）从一个上下文到另一个上下文的移动。 将支持SPAN目标流量的数据端口移动到目标VDC之后，这些SPAN目标端口可能被配置为能够接收SPAN数据流量。

Abstract: An example method for zero touch configuration and synchronization of a service appliance in a network environment includes receiving, at an appliance port on a service appliance, an indication that a switch port on a switch changed from an inactive status to an active status, the appliance port being connected over a network to the switch port, starting a bootstrap protocol, including by receiving at the service appliance from the switch, a bootstrap message from a service executing in the switch, creating, by the service appliance, an empty port channel at the service appliance, adding, by the service appliance, the appliance port to the port channel, and associating, by the service appliance, the service to the port channel in a cache.

Abstract: An example method is provided and includes configuring a service on a network element; associating a directly connected port with the service to create a port channel between the network element and a directly connected service appliance, the port channel comprising a plurality of member ports; performing an auto-discovery process for each of the member ports; and, upon successful completion of the performing, indicating on the network element that the service appliance is operational. In certain embodiments, the network element includes an intelligent service card manager module (“ISCM”) that forms part of a Remote Integrated Service Engine (“RISE”) element with a corresponding intelligent service card client module (“ISCC”) installed on the service appliance. The method may further include, upon unsuccessful completion of the auto-discovery process, repeating the auto-discovery process.

Abstract: The present disclosure describes several key features of an agent deployable on a service appliance: agent architecture/design, transport and channel abstractions of the agent, new message definition components, channel switching (e.g., platform independent processing), Channel state machine, platform dependent hooks (e.g., memory, timers), Service key data store, and Secure channel infrastructure. Many of these features alleviate the vendor of the service appliance from having to provide the features. The features and standardization thereof enable the system to be more robust (and increases code quality). Speed of integration is decreased while the risk of integration issues is also decreased. Updates to the agent can be deployed in a controlled and efficient manner. Furthermore, the agent can ensure security between a switch and the agent. The agent deployed and running on vendor appliances provides a unique way to present transport channels that run between the switch, agent, and other service appliance components.

Abstract: In one embodiment a forwarding policy from a first network node coupled to a network element is received. The forwarding policy specifies an address of a second network node coupled to the network element. A plurality of ports of the network element are identified, wherein the second network node is accessible from the network element through each of the plurality of ports. The forwarding policy is applied to the plurality of ports of the network element. Network traffic received at a port of the plurality of ports from the second network node is forwarded to the first network node.
