Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter5 Configuring the MGX 8230 Shelf MGX 8230 MGX to BPX Feeder
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 nu m be r of c onnections 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 t o par t iti on M G X 8 2 30 PX M r es o urce s.
Step 4 Activate the uplink line by executi ng 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 f or t he feeder application.
Step 5 If necessary, you can configure line characteristics by using the cnfln command.
Step 6 Create logical ports f or the physical line by exec uting 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 physic al 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.
Step 7 Optionally use cnfportrscprtn to specify the resources th at a c ontroller has on a port:
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-connectio ns or 34 for inband ATM
PVCs for network ma na gement.
controller is a string identifying the network controller—”PAR,” “PNNI,” or “TAG. ”
ingress_%BW is the percentage o f i n gress bandwidth—a number in the range 0–100.
egress_%BW is the percentage of egress bandwidth —a n um ber in the range 0–100.
