Traffic Copy Policies
Using Cisco DNA Center, you can set up an Encapsulated Remote Switched Port Analyzer (ERSPAN) configuration such that the IP traffic flow between two entities is copied to a specified destination for monitoring or troubleshooting.
To configure ERSPAN using Cisco DNA Center, create a traffic copy policy that defines the source and destination of the traffic flow that you want to copy. You can also define a traffic copy contract that specifies the device and interface where the copy of the traffic is sent.
Note |
Because traffic copy policies can contain either security groups or IP network groups, throughout this guide, we use the term groups to refer to both security groups and IP network groups, unless specified otherwise. |
