Down Port—AXSM, AXSM-E, AXSM-32-T1E1-E, AXSM-XG
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.
On a UNI, the connections continue to exist, but remain in the failed state until you enable the port by
executing upport.
Caution For AXSM-E and AXSM-XG, do not execute this command unless you want to change the SCT
configuration. All connection configurations on the port are lost when you execute this command on the
AXSM-E or AXSM-XG.

MGX8850.1.AXSM.a > dnport 1
ifNum A logical port (interface) number. Only one logical port is allowed if the line operates
as a UNI or NNI. For the virtual network to network interface (VNNI), multiple ports
can exist on a line. The ranges are:
• AXSM: 1–60
• AXSM-E: 1–32
• AXSM-XG: 1–126
Use dspports or dspport as needed to determine the need to disable a port.
