Verifying the ATM Configuration
The supported set of configuration options varies between the ATM1 and ATM2 IQ interfaces. If you configure an ATM1 interface using ATM2 IQ configuration options, the configuration does not commit. The same occurs if you configure an ATM2 IQ interface with ATM1 options. See the Junos Network Interfaces Configuration Guide for more information on the options supported for ATM1 and ATM2 IQ interfaces.

Verifying the Configuration of an ATM1 Interface
Purpose
The Junos OS assumes an ATM1 interface configuration if you include the maximum-vcs statement without the pic-type statement at the [edit interfaces at-fpc/pic/port atm-options] hierarchy level,
Action
To check the configuration of an ATM1 interface, use the following Junos OS CLI operational mode command:
Sample Output 1
user@host> show configuration interfaces at-0/1/0 atm-options {
vpi 1 {
maximum-vcs 1024;
}
}
unit 100 {
vci 1.100;
family inet {
address 25.25.25.2/30;
}
}
Sample Output 2
user@host> show configuration interfaces at-1/0/0 atm-options {
pic-type atm1;
vpi 0 maximum-vcs 256;
vpi 1 maximum-vcs 512;
}
Meaning
The sample output shows the correct configuration of an ATM1 interface. Sample output 1 shows the maximum-vcs statement configured on an ATM interface. Because the pic-type statement is not included in the configuration, this interface is assumed to be an ATM1 interface. Use the show chassis hardware command to verify that the interface is an ATM1. Otherwise this could be the incorrect configuration of an ATM2 IQ interface. Sample output 2 shows the correct configuration of an ATM1 interface with the pic-type statement and the maximum-vcs statement.
Verifying the Configuration of an ATM2 IQ Interface
Purpose
ATM2 IQ interfaces must not have the maximum-vcs statement included in the configuration.
Action
To check the configuration on an ATM2 IQ interface, use the following CLI operational mode command:
Sample Output 1
user@host> show configuration interfaces at-0/1/0 atm-options {
vpi 1;
}
unit 100 {
vci 1.100;
family inet {
address 25.25.25.1/30;
}
}
Sample Output 2
user@host> show configuration interfaces at-2/2/0 atm-options {
pic-type atm2 ;
vpi 1;
}
unit 100 {
encapsulation ether-over-atm-llc;
vci 1.100;
shaping {
vbr peak 66k sustained 66k burst 40;
}
family inet {
address 192.168.5.1/24;
}
}
[...Output truncated...]
Meaning
The sample output shows the correct configuration of an ATM2 IQ interface. The first example shows that the interface at-0/1/0 has ATM options configured and the logical interface at-0/1/0.100. Sample output 2 shows another interface at-2/2/0 with the PIC type configured.
 | Note: The ATM2 IQ interface does not have the maximum-vcs statement included in the configuration. |
Verifying the Configuration of an ATM MIC Interface
Purpose
Verify that the ATM MIC interface is configured correctly. ATM MIC interfaces do not have the maximum-cvs and pic-type statements included in the configuration.
Action
To check the configuration of the ATM MIC interface:
atm-options {
vpi 7;
}
unit 100 {
encapsulation atm-vc-mux;
vci 7.100
family inet {
address 10.10.10.1/32;{
destination 10.10.20.1
}
}
}Meaning
The sample output shows the correct configuration of an ATM MIC interface. The sample output shows that the interface at-2/2/0 has ATM options configured.
| Note: The ATM MIC interface does not have the maximum-cvs statement or the pic-type statement included in the configuration. |
