Up Port
The upport command returns a logical po rt to the up state (or “ups” the port) so the port can again carry
traffic. The upport command concludes possible re-configuration or troubleshooting steps. Before you
execute upport, you must have downed the port by executing dnport. Throughout the sequence of
downing and upping a port, the configuration for the port remains intact whether the logical port is a
UNI or an NNI.
The routes for connections vary by inter fa ce t yp e:
•After you re-enable an NNI port through upport, you c an not re tur n th e re-r oute d co nnec tion s to th e
upped port. The PXM45 routes connections over the trunk as needed.
•On a UNI, the connections co nt in ue to exist but remain in the faile d state until you enable th e p o rt
by executing upport.
