Chapter 6 Card and Service Configuration

The Processor Switching Module

•line has the range 1–4 but depends on the number of lines on the back card.

For a feeder, you can activate only one line. For a stand-alone, you can activate more than one line if the back card has multiple lines. One line must serve as the trunk to the ATM network. With an OC-3, T3, or E3 card, remaining lines can serve as UNI ports to CPE.

Step 3 If necessary, modify the characteristics of a line by using cnfln.

Step 4 Configure logical ports for the physical line by executing addport. Execute addport once for each logical port. 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 user-ports or 34 for inband ATM PVCs that serve as management connections.

•line_num is the line number in the range 1–4 but depends on the type of uplink card.

•pct_bw is the percentage of bandwidth. The range is 0–100. This parameter applies to both ingress and egress.

•min_vpi is the minimum VPI value. On a feeder, the range is 0–4095. On a stand-alone node, the range is 0–255.

•max_vpi is the maximum VPI value. On a feeder, the range is 0–4095. On a stand-alone node, the range is 0–255.

Using an example of 100% of the bandwidth on one logical port 1:

addport 1 1 100 1 200

where the first “1” is the logical port number; the second “1” is the line number on the PXM1 back card to which you are assigning this logical port number; “100” is the percentage of bandwidth this port has in both directions; and the VPI range is 1–200.

Step 5 If necessary, use cnfportrscprtn to modify port-level resources for a controller:

cnfportrscprtn <port_no> <controller> <ingress_%BW> <egress_%BW>

•<min_VPI> <max_VPI> <min_VCI> <max_VCI> <max_GLCNs>

•port_no is the logical port number 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 in the range 0–100.

•egress_%BW is the percentage of egress bandwidth in the range 0–100.

•min_vpi is the minimum VPI in the range 0–4095.

•max_vpi is the maximum VPI in the range 0–4095.

•min_vci is the minimum VCI in the range 0–65535.

•max_vci is the maximum VCI in the range 0–65535.

•max_chans is the maximum GLCNS in the range 0–32767.

Step 6 On a stand-alone node, specify the cell header type as needed by executing cnfatmln.

cnfatmln <line_num> <type>

•line_num is the line number in the range 1–4.

•type is either 2 for UNI or 3 for NNI (the default).
