IISP trunks are typically used only at PNNI border nodes to connect a PNNI network to a IISP network. To configure the IISP trunk, you have to use the BPX command line interface as well as the ESP configuration interface.
This appendix provides a sample IISP trunk configuration based on the Example IISP Trunk in Figure L-1. The configuration example is divided into the following two sections:
The BPX switch configuration includes the following steps:
Step 1 Confirm BXM card existence by logging in to the BPX switch and displaying cards:
dspcds
Confirm there is a BXM card in slot 1 (as indicated in Figure L-1).
Step 2 Configure the BXM port:
(a) upln 1.3
(b) cnfrsrc 1.3, setting the following parameters:
As show in the Figure L-2:
svcbpx1 TN Userxxxxx BPX 15 9.1.xx May 26 1998 10:43 PDT
Port/Trunk : 1.3
Maximum PVC LCNS: 256 Maximum PVC Bandwidth:20000
Min Lcn(1) : 0 Min Lcn(2) : 0
Partition 1
Partition State : Disable
This Command: cnfrsrc 1.2 256
Maximum PVC Bandwidth [353208]: 20000
Step 3 Configure the BXM port with the following command:
cnfport 1.3
Configure the following parameters:
As shown in Figure L-3:
svcbpx1 TN Userxxxxx BPX 15 9.1.xx May 26 1998 10:48 PDT Port: 1.3 [ACTIVE ] Interface: LM-BXM Type: NNI %Util Use: Disabled Speed: 353208 (cps) Vc Shaping: Disabled Shift: SHIFT ON HCF (Normal Operation) SIG Queue Depth: 640 Protocol: NONE SVC Channels: 1000 SVC VPI Min: 0 SVC VPI Max: 255 SVC Bandwidth: 300000 (cps)
Confirm that the SVC channels, SVC VPI min/max, and bandwidth are assigned properly.
Step 4 Finally configure the BXM Port Queue with the following command:
cnfportq 1.3
Configure the following parameters:
Confirm port queue configuration with the dspportq command (dspportq 1.3) as shown Figure L-4:
svcbpx1 TN StrataCom BPX 15 9.1.0E May 26 1998 10:49 PDT
Port: 1.3 [ACTIVE ]
Interface: LM-BXM
Type: UNI
Speed: 353208 (cps)
SVC Queue Pool Size: 200
CBR Queue Depth: 600
CBR Queue CLP High Threshold: 80%
CBR Queue CLP Low Threshold: 60%
CBR Queue EFCI Threshold: 60%
VBR Queue Depth: 5000 UBR/ABR Queue Depth: 20000
VBR Queue CLP High Threshold: 80% UBR/ABR Queue CLP High Threshold: 80%
VBR Queue CLP Low Threshold: 60% UBR/ABR Queue CLP Low/EPD Threshold:60%
VBR Queue EFCI Threshold: 60% UBR/ABR Queue EFCI Threshold: 20%
Last Command: dspportq 1.3
Next Command:
You must configure both the IISP addresses for static routing and NNI Information for the IISP trunk from the ESP Configuration Interface. These steps are divided into the following two sections:
Step 1 Telnet to the ESP and execute "cli" to start the ESP Configuration Interface.
Step 2 From the ESP Main Menu enter 1 to bring up the ESP Information menu shown in the following example:

Then enter remote node name to node list. For exmaple, the remote node name show here, "iispnode".
Enter c to commit the record.
Step 5 Now, return to Node List screen, move cursor to the remote node. Hit return. It will bring up the node address screen shown in the following example:
