<P style="TEXT-ALIGN: justify; LINE-HEIGHT: normal; MARGIN-BOTTOM: 1pt" mcestyle="text-align: justify; line-height: normal; margin-bottom: 1pt;">Firstly, not all switch model support TDR. TDR feature first came out with the Catalyst 2960. So here is the list of which ones will work and will not:

2. •1. The 2960 will support TDR in both the FastEthernet and dual-personality GigiabitEthernet port, however, when used on a FastEthernet port, TDR will only test the first two pairs, namely Pairs A & B. For obvious reasons, Pairs C and D will not be tested when used on non-GigabitEthernet ports.
