Port Mirroring
Learn about port mirroring on the ACX7000 family of routers. The ACX7000 family of routers includes ACX7020, ACX7024, ACX7024X, ACX7100, ACX7332, ACX7348, and ACX7509 routers.
Networking devices, such as ACX7000 family of routers, uses port mirroring to send a copy of network packets seen on one port to a network-monitoring connection on another port. This feature mirrors the packet for a given interface in a specified direction (ingress or egress) to a destination connected to a device (laptop or server) running an analyzer application. The analyzer application helps monitor compliance, enforce policies, detect intrusions, analyze network performance, correlate events, and address other network issues.
Mirroring has two components:
-
Source of mirror: The interface receiving the input traffic that is copied (mirrored).
-
Destination of mirror: The interface to where the copies of packets are sent and to which a device running an analyzer is connected.
On an ACX7000 family of routers, use the analyzer statement at the
[edit forwarding-options] hierarchy to configure port mirroring for
incoming and outgoing traffic.
Here is a sample port mirroring configuration on an ACX7000 family of routers.
