Configuring the ATM PIC Type
For ATM1 and ATM2 IQ interfaces, the JUNOS software does not determine from the interface name at- fpc/pic/port whether your routing platform 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:
- [edit interfaces interface-name atm-options]
- pic-type (atm1
| atm2);
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, the JUNOS software 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, the JUNOS software assumes you are configuring an ATM2 IQ interface, and sets the PIC type option accordingly.
- If you include the promiscuous-mode statement in the configuration of an ATM2 interface, you must also include the pic-type atm2 statement.
Example: Configuring the ATM PIC Type
Configure the PIC type on an ATM1 and an ATM2 interface.
On an ATM1 Interface
- [edit interfaces]
- at-1/0/0 {
-
- atm-options {
- pic-type atm1;
- vpi 0 maximum-vcs 256;
- vpi 1 maximum-vcs 512;
- }
- ...
- }
On an ATM2 IQ Interface
- [edit interfaces]
- at-1/1/0 {
-
- atm-options {
- pic-type atm2;
- vpi 0;
-
- vpi 2 {
- oam-period 6;
- }
- }
- ...
- }
