1. Short frames are frames smaller than 64 bytes.
2. Long frames are frames longer than the maximum frame length configured for this port.
Port Mirror
You can configure port mirror on this page.
To solve network problems, selected traffic can be copied, or mirrored, to a mirror port where a frame
analyzer can be attached to analyze the frame flow.
The traffic to be copied to the mirror port is selected as follows:
All frames received on a given port (also known as ingress or source mirror).
All frames transmitted on a given port (also known as egress or destination mirror).
Port to mirror is also known as the mirror port. Frames from ports that have either source (rx) or destination
(tx) mirror enabled are mirrored to this port. Disabled option disables mirror.
Label
Description
Port
The switch port number to which the following settings will be applied.
Mode
Drop-down list for selecting a mirror mode.
Rx only
: only frames received on this port are mirrored to the mirror port. Frames
transmitted are not mirrored.
Tx only
: only frames transmitted from this port are mirrored to the mirror port.
Frames received are not mirrored.
Disabled
: neither transmitted nor received frames are mirrored.
Enabled
: both received and transmitted frames are mirrored to the mirror port.
Note: for a given port, a frame is only transmitted once. Therefore, you cannot
mirror Tx frames to the mirror port. In this case, mode for the selected mirror port
is limited to
Disabled
or
Rx only
.
