Configuring the ATM PIC Type
For ATM1 and ATM2 IQ interfaces, the Junos OS does not determine from the interface name at- fpc/pic/port whether your router has an ATM1 or ATM2 IQ PIC installed. You can configure the PIC type as ATM1 or ATM2 IQ by including the pic-type statement at the [edit interfaces interface-name atm-options] hierarchy level:
On MX Series routers with ATM MICs with SFP, you do not have to configure the PIC type because Junos OS automatically configures the PIC type as ATM MIC.
 | Note: This topic uses the term PIC for ATM MICs where the reference is to a CLI or Junos OS entity. |
The following guidelines apply to configuring the ATM PIC type:
- If you include the pic-type statement in the configuration, and you include other statements at the [edit interfaces interface-name atm-options] hierarchy level that do not match the configured PIC type, the configuration does not commit. For example, you cannot commit a configuration that includes the pic-type atm2 statement and the maximum-vcs statement.
- If you do not include the pic-type statement and you do include the maximum-vcs statement in the configuration, Junos OS assumes you are configuring an ATM1 interface, and sets the PIC type option accordingly. If you do not include the maximum-vcs statement in the configuration, Junos OS assumes you are configuring an ATM2 IQ interface, and sets the PIC type option accordingly.
- On MX Series routers with ATM MICs with SFP, Junos OS automatically sets the PIC type to ATM MIC.
- If you include the promiscuous-mode statement in the configuration of an ATM2 interface, you must also include the pic-type atm2 statement.
