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.

Methods and systems for a network appliance module enabling dynamic VDC aware span

A method is provided in one example embodiment and includes identifying a first data center configured to receive a request initiated by an end user. The method also includes detecting a presence of a wide area application service (WAAS) and identifying a second data center. The method further includes signaling, in response to the presence of the WAAS, to redirect data packets associated with the request to the second data center. In more specific embodiments, the signaling includes adding a TCP option to packets of a session associated with the end user to inform components of redirecting capabilities of a WAAS element. The detecting can include recognizing a transmission control protocol (TCP) option in detecting the presence of the WAAS. The TCP option can be used to identify capabilities of a WAAS element that is involved in servicing the request of the end user.

Redirection of a request for information

Conventional SSL termination devices support secure connections only to a predetermined destination address. An SSL termination device accepts a plaintext connection and associate it to a secure connection to an arbitrary destination endpoint by intercepting a connection request from the local subnetwork, identifying the intended destination of the connection, and establishing a secure connection to the destination, bridges the local connection and the secure connection to provide a connection through the gateway device. The SSL termination device identifies an outgoing secure connection request from a client, and intercepts the connection request to identify the recipient destination. The SSL termination device establishes a secure connection using the identified destination, and associates the connections by mapping the intercepted connection to the recipient. The identified recipient allows the secure connection to the destination, and the mapping allows message traffic received from the client over the local connection to be mapped to the destination.
