6-6 Port Mirroring
The Switch allows you to copy frames transmitted and received on a port and redirect the copies to another port.You can attach a monitoring device to the
mirrored port, such as a sniffer or an RMON probe, to view details about the packets passing through the first port.This is useful for network monitoring and
troubleshooting purposes.To view the Setup Port Mirroring window, click Port Mirroring in the Configuration folder.
Figure 6- 7. Setup Port Mirroring window
To configure a mirror port:
•
Select the Source Port from where you want to copy frames and the Target Port, which receives the copies from the source port.
•
Select the Source Direction, Ingress, Egress, or Both and change the Status drop-down menu to Enabled.
•
Click Apply to let the changes take effect.
Note:
You cannot mirror a fast port onto a slower port. For example, if you try to mirror the traffic from a 100Mbps port onto a 10Mbps port,
this can cause throughput problems.The port you are copying frames from should always support an equal or lower speed than the port to which
you are sending the copies.Also, the target port for the mirroring cannot be a member of a trunk group. Please note a target port and a source port
cannot be the same port.
6-7 Link Aggregation
Understanding Port Trunk Groups
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline.
The AT-9724TS supports up to 32 port trunk groups with 2 to 8 ports in each group.A potential bit rate of 8000Mbps can be achieved.
