Rx CRC/Alignment

Rx Undersize
The number of short1 frames received with a valid CRC.
Rx Oversize
The number of long2 frames received with a valid CRC.
Rx Fragments
The number of short1 frames received with an invalid CRC.
Rx Jabber
The number of long2 frames received with an invalid CRC.
Rx Filtered
The number of received frames filtered by the forwarding process.
Tx Drops
The number of frames dropped due to output buffer congestion.
Tx Late/Exc.Coll.

1. Short frames are frames smaller than 64 bytes.
2. Long frames are frames longer than the maximum frame length configured for this port.
5.10.3 Port Mirroring
You can configure port mirroring 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 mirroring).
All frames transmitted on a given port (also known as egress or destination mirroring).
Port to mirror is also known as the mirror port. Frames from ports that have either source (rx) or destination (tx) mirroring enabled
are mirrored to this port. Disabled option disables mirroring.
