Variable Value
• 1—inversed
• 2—normal
•
3—invalid
Pair3Swap Indicates the status of the pin assignments
for the third pair in the cable. Values include:
• 1—normal
• 2—swapped
• 3—invalid
• 4—error
Pair3Skew Indicates the differential length, in meters, of
the third pair in the cable. The skew
measurement can be performed only when
the cable gigabit link is up, regardless of
traf
fic activity. A value of –1 means an error
occurred with the length measurement.
Pair4Polarity Indicates the polarity of the fourth pair in the
cable. This capability is available only when
the cable gigabit link is up, regardless of
traf
fic activity. Values include:
• 1—inversed
• 2—normal
• 3—invalid
Pair4Swap Indicates the status of the pin assignments
for the fourth pair in the cable. Values
include:
• 1—normal
• 2—swapped
• 3—invalid
• 4—error
Pair4Skew Indicates the differential length, in meters, of
the fourth pair in the cable. The skew
measurement can be performed only when
the cable gigabit link is up, regardless of
traffic activity. A value of –1 means an error
occurred with the length measurement.
