Measures reported by CisSDWTunnelTest

A tunnel is a virtual point-to-point link across a multipoint-access network, such as the Internet. Tunnels help you to create secure connections between remote users and a private corporate network via the internet. In a sense, a tunnel emulates a WAN link.

When communication is initiated across the components of the Cisco SD-WAN, tunnels created over the WAN environment wraps up the data packets into another data packet and encrypts the package that is to be sent through the tunnel. At the receiver's end, the tunneling device/protocol deciphers the package and then strips the wrapped data packet to read and access the original message and reveal the source of packet and other classified information. This way, secure communication is possible with the tunnels. If the traffic through the tunnels are too high or if a tunnel is not available, then, data transmission and reception by the tunnels will take longer than usual which will inturn affect the performance of the Cisco SD- WAN appliance. To avoid such performance degardation, administrators should constantly monitor the level of traffic flowing through the tunnels created on the target Cisco SD-WAN. The CisSDWTunnelTest test helps administrators in this regard!

This test auto-discovers the tunnels created on the target Cisco SD-WAN and for each tunnel, measures the level of traffic flowing through the tunnel. Using this test, administrators can be proactively alerted to the discrepancies in the data and packet transmission and reception. Administrators can also figure out the tunnel through which maximum data/packets are transmitted/received.

Outputs of the test : One set of results for each component:tunnel in the target Cisco SD-WAN appliance that is being monitored.

The measures made by this test are as follows:
