Product Manual

To configure a mirror port:
DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch
Figure 6- 6. Setup Port Mirroring window
• 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 100 Mbps port onto a 10 Mbps 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.
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 DES-3526 supports up to six port trunk groups with 2 to 8 ports in each group. A potential bit rate
of 8000 Mbps can be achieved.
