Down Port
The dnport command disables (or downs) a logical port and thereby halts all traffic on the logical port.
The usual purpose for using dnport is troubleshooting. The configuration for the port remains intact
whether the logical port is a UNI or an NNI. The command for enabling a downed port is upport.

For an NNI, the PXM45 de-routes the failed connections then re-routes them through other trunks. After
you re-enable an NNI port through upport, you cannot return the re-routed connections to the upped
port. The PXM45 routes connections over the trunk as needed.

as a UNI or NNI. For the virtual network to network interface (VNNI), multiple ports
can exist on a line. For AXSM, the range 1–60. Use dspports or dspport as needed
to determine the need to disable a port.
