Overview
This section explains the operational stages of ACL-based traffic mirroring and how the router processes defined rules. It describes how the system uses specific keywords and configurations to determine which packets are mirrored to the designated destination port.
Summary
These stages describe how ACL-based traffic mirroring works.
-
The router creates an ACL.
-
This ACL defines the traffic to be mirrored and specifies the packets to be mirrored.
-
The keywords defined in the ACL designates that the packet is mirrored to the destination port.
-
The rules defined in the ACL determine the behavior for traffic.
Workflow
| When the system.. |
But.. |
Then.. |
|---|---|---|
| configures the acl command on the source mirroring port |
the ACL configuration command does not use the capture keyword |
the router does not mirror the traffic. |
| uses ACL configuration with the capture keyword |
you have not configured the acl command on the source port |
the router mirrors the traffic, but does not apply access list configuration. |
