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.
