then to use those settings. The other options are Auto, 10M/Half, 10M/Full,
100M/Half, 100M/Full, and 1000M/Full. There is no automatic adjustment of port
settings with any option other than Auto.
Flow Control
Displays the flow control scheme used for the various port configurations. Ports
configured for full-duplex use 802.3x flow control, half-duplex ports use
backpressure flow control, and Auto ports use an automatic selection of the two.
The default is Disabled.
Learning
Enable or disable MAC address learning for the selected ports. When Enabled,
destination and source MAC addresses are automatically listed in the forwarding
table. When learning is Disabled, MAC addresses must be manually entered into
the forwarding table. This is sometimes done for reasons of security or efficiency.
See the section on Forwarding for information on entering MAC addresses into
the forwarding table. The default setting is Disabled.

Port Mirroring
Figure 6- 5. Setup Port Mirroring window
To configure a mirror port:
1. Select the Source Port from where you want to copy frames and the Target Port, which receives the copies from
the source port.
2. Select Ingress, Egress, or None and change the Status drop-down menu to Enabled.
3. 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
