Slevin, I think you are right...
But I think that the correct command to use in this case will be "udld
port aggressive", because we have "twisted-pair links":
"UDLD supports two modes of operation: normal (the default) and
aggressive. In normal mode, UDLD can detect unidirectional links due to
misconnected interfaces on fiber-optic connections. In aggressive mode,
UDLD can also detect unidirectional links due to one-way traffic on
fiber-optic and twisted-pair links and to misconnected interfaces on
fiber-optic links. "

.2_25_see/configuration/guide/swudld.html#wp1042035
SW1(config)# Int ra fa 0/23-24
SW1(config)# udld port aggressive
SW2(config)# Int ra fa 0/23-24
SW2(config)# udld port aggressive
Please, correct me if I am wrong.
Thanks

i think udld global is only for fibre optics.for copper ports only
udld on interface shud suffice.THis is as per IEWB wb lab4 task 1.5
