Configure resources at the port level as needed by executing cnfportrscprtn:
cnfportrscprtn <port_num> <controller_name>
Configuring Bulk Distribution and Redundancy
You can configure either bulk distribution alone, redundancy alone, or both of these features according
to the restrictions in the “Redundancy Support for the Eight-Port CESM” section on page 6-52. On the
CLI of the PXM1, execute addlink for bulk distribution (T1 only) before you enter addred for
redundancy. To configure bulk distribution enter addlink to create the links:
addlink <T3 line number> <T1 line number> <Target Slot number> <Slot line number>
port_num Logical port number in the range 1–256. When you subsequently add a connection
through the preferred command addcon or the addchan command (which requires
NSAP format), you must indicate a logical port by using this singular port_num
regardless of the number of DS0s. (You can add 1–24 DS0s to a single port_num
through the other addport parameters.)
line_num DS1 number in the range 1–56 to which you assign the DS0 when both lines are
active. If you activate only one line, the range is 1–28. You can assign up to 24
contiguous DS0s to one DS1. Each physical line supports up to 28 DS1s. The
number of DS0s cannot span more than DS1.
begin_slot Beginning DS0 timeslot in 1 base. For example, on port number 50, you could
specify begin_slot to be 9 then specify num_slot to be in the range 1–16.
num_slot Number of DS0s in the associated DS1. Note that the number of DS0s cannot be
such that the logical port spans more than DS1.
port_type Number representing the mode of operation for the logical port—1 for Frame
Relay, 2 for FUNI mode-1a, and 3 for frame forwarding.
port_num Logical port number in the range 1 – 192 for T1 or 1 – for E1.
controller_name Name of the network control application. Enter one of the following strings:
PAR, PNNI, or MPLS
• T3 line number MGX-SRM-3T3/C line number in the format slot.line. The slot can
be 15 or 31. The range for port is 1–3
• T1 line number Starting T1 line number within the T3 line. The range for the T1 line
number is 1–28.
