Table 141: show diagnostics tdr Output Fields (continued)
Field DescriptionField Name
Indicates whether the connection speed is being downshifted:
• No Downshift—No downshifting of connection speed.
• Downshift occurs—Connection speed is downshifted to 10 or 100
Mbs. This occurs if the cable is a two-pair cable rather than the
four-pair cable required by Gigabit Ethernet.
(Displayed only when the interface option is used.)
