General PXM1E Configuration Procedures
Step 1
Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2
To display the automatic configuration status of a port, use the dsppnport command. For example:
mgx8830a.1.PXM.a >
dsppnport
1:2.3:1
Port: 1:2.3:1 Logical ID: 16845569
IF status: up Admin Status: up
UCSM: enable SVC Routing Pri: 8
Auto-config: enable Addrs-reg: enable
IF-side: network IF-type: nni
UniType: private Version: pnni10
PassAlongCapab: n/a
Input filter: 0 Output filter: 0
minSvccVpi: 0 maxSvccVpi: 4095
minSvccVci: 35 maxSvccVci: 65535
minSvpcVpi: 1 maxSvpcVpi: 4095
(P=Configured Persistent Pep, NP=Non-Persistent Pep, Act=Active)
#Spvc-P: #Spvc-NP: #SpvcAct: #Spvp-P: #Spvp-NP: #SpvpAct:

#Svcc: #Svpc: #Ctrl: Total:
p2p : 1 0 0 1
p2mp: 0 0 0 0
Total: 1
The Auto-config field shows whether the automatic configuration feature is enabled or disabled.
Step 3
If you want to enable or disable automatic configuration, bring down the port to be configured with the
dnpnport command. For example:
mgx8830a.1.PXM.a >
dnpnport 1:2.3:1
Step 4
To enable or disable the automatic configuration feature, enter the cnfautocnf command as follows:
mgx8830a.1.PXM.a >
cnfautocnf
<
portid
> <
yes
|
no
>
Replace portid with the port address using the format slot:bay.line:ifnum. These parameters are
described in
Enter yes to enable automatic configuration or enter no to disable automatic configuration. The default
is yes.
Step 5
Up the port you configured with the uppnport command. For example:
mgx8830a.1.PXM.a >
uppnport
1:2.3:1
Step 6
To verify the change, re-enter the dsppnport command.
Configuring ILMI Dynamic Addressing
Dynamic ATM addressing is enabled by default on all PXM1E ports. Once ILMI is started, ILMI can
negotiate ATM addresses for CPE connected to the port. To determine the ATM address for the CPE, the
switch uses a 13-byte ILMI prefix that is assigned to the port, a 6-byte end system ID, and a 1-byte
selector byte. The end system ID and selector byte are defined on the end system. Depending on the end
system configuration, the end system ID may correspond with the interface MAC address. For dynamic
addressing to work, the remote device must support it. ILMI versions 3.x and 4.0 support dynamic
address registration.
