The number of line pairs included. For example,
the twisted pair comprises four pairs of lines.
Status of the current line pair: OK, Short or
Open. In general, the 100 Mbit/s twisted pairs A
and B are OK, C and D are Short. The 1000
Mbit/s twisted pairs A, B, C and D are all OK.
Length of the line in meter. Only the length of the
OK line pair is effective. Because the length is
calculated based on the signal transmission time,
there may be a certain difference. The length of a
Short or Open line pair measures the distance
from the port to the faulty point.
Use this command to select the medium type for an interface. Add no in the
command to restore it to the default setting.
medium-type { auto-select [prefer [fiber | copper]] | fiber | copper }
The preferred medium type for the interface is selected.
Auto-select the medium type for the interface.
Interface configuration (physical interface, except for AP and SVI)
If a port can be used as an optical or electrical port, you can only select either.
Once the media type is specified, the attributes of the port such as status, duplex,
flow control, and rate, apply to the currently selected media type. After the port
