Cisco MGX 8230 Edge Concentrator Installation and Configuration

Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001

Chapter 5 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 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.

Step 7 Optionally use cnfportrscprtn to specify the resources that a controller 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-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.
