Chapter 5
Configuring the MGX 8230 Shelf
Step 3
Optionally, modify the resource partitioning for the whole card by executing the cnfcdrscprtn
command. You can view resource partitioning through dspcdrscprtn.
cnfcdrscprtn <number_PAR_conns> <number_PNNI_conns> <number_TAG_conns>
number_PAR_conns is the number of connections in the range 0–32767 available to PAR.
number_PNNI_conns is the number of connections in the range 0–32767 available to PNNI.
number_TAG_conns is the number of connections in the range 0–32767 available to Tag.
For example, you could reserve 10,000 connections for each controller on the MGX 8230 PXM with:
cnfcdrscprtn 10000 10000 10000
Note
In this release, there is no need to partition MGX 8230 PXM resources.
Step 4
Activate the uplink line by executing addln according to the following syntax:
addln -ds3 <slot.line> | -e3 <slot.line> | -sonet <slot.line>
where:
•
-ds3 indicates a T3 line
-e3 indicates an E3 line
•
-sonet indicates an OC-3 or OC-12 line
•
slot is always 1 for the MGX 8230 PXM whether the active MGX 8230 PXM is in slot 1 or 2
•
•
line has the range 1–4 but depends on the number of lines on the uplink card
You can activate only one MGX 8230 PXM line for the feeder application.
Step 5
If necessary, you can configure line characteristics by using the cnfln command.
Step 6
Create logical ports for the physical line by executing addport once for each logical interface. (Related
commands are cnfport, dspports, and delport.)
addport <port_num> <line_num> <pct_bw> <min_vpi> <max_vpi>
port_num is the number for the logical port. The range is 1–32 for standard connections, and 34 is the
port number reserved for inband ATM PVCs for network management.
line_num is the physical line in the range 1–N. N is the number of lines on the card.
pct_bw is percentage of bandwidth. The range is 0–100. This parameter applies to both ingress and
egress.
min_vpi is the minimum VPI value. The range is 0–4095.
max_vpi is the maximum VPI value. The range is 0–4095.
Optionally use cnfportrscprtn to specify the resources that a controller has on a port:
Step 7
cnfportrscprtn <port_no> <controller> <ingress_%BW> <egress_%BW>
<min_VPI> <max_VPI> <min_VCI> <max_VCI> <max_GLCNs>
port_no is the number for the logical port in the range 1–32 for user-connections or 34 for inband ATM
PVCs for network management.
controller is a string identifying the network controller—"PAR," "PNNI," or "TAG."
ingress_%BW is the percentage of ingress bandwidth—a number in the range 0–100.
egress_%BW is the percentage of egress bandwidth—a number in the range 0–100.
