1G Pair Status
result
The Pair Status results for 1G electrical links provide the
current pair assignments for the link. MDI pairs for 1G elec-
trical links are assigned during the process of auto-negotia-
tion; therefore, if for any reason the link becomes inactive, and
then the link is re-established, the pair assignments could
potentially change. For example, the first time you establish a
link after auto-negotiation, the following pairs could be
assigned:
If the link goes down (becomes inactive), and then is re-estab-
lished, the following pairs could be assigned:
MDI cross over MDI
MDI straight through MDIX
MDIX cross over MDIX
