For AS PICs, MultiServices PICs, and the internal Adaptive Services Module (ASM) in the M7i platform, there are two service packages: Layer 2 and Layer 3. Both service packages are supported on all adaptive services interfaces, but you can enable only one service package per PIC, with the exception of a combined package supported on the ASM. On a single routing platform, you can enable both service packages by installing two or more PICs on the platform.
You enable service packages per PIC, not per port. For example, if you configure the Layer 2 service package, the entire PIC uses the configured package. To enable a service package, include the service-package statement at the [edit chassis fpc slot-number pic pic-number adaptive-services] hierarchy level, and specify layer-2 or layer-3:
[edit chassis fpcslot-numberpicpic-numberadaptive-services]
service-package (layer-2 | layer-3);
To determine which package an AS PIC supports, issue the show chassis hardware command: if the PIC supports the Layer 2 package, it is listed as Link Services II, and if it supports the Layer 3 package, it is listed as Adaptive Services II. To determine which package a MultiServices PIC supports, issue the show chassis pic fpc-slot slot-number pic-slot slot-number command. The Package field displays the value Layer-2 or Layer-3.

NOTE: The ASM has a default option that combines the features available in the Layer 2 and Layer 3 service packages. |
After you commit a change in the service package, the PIC is taken offline and then brought back online immediately. You do not need to manually take the PIC offline and online.
The services supported in each package differ by PIC and platform type. Table 5 lists the services supported within each service package for each PIC and platform. Some of these services are also available on J-series Services Routers, but they are implemented in a different way and do not use the Layer 2 and Layer 3 service packages. For more information, see the J-series Services Router Advanced WAN Access Configuration Guide.
On the AS and MultiServices PICs, link services support includes JUNOS software CoS components, LFI (FRF.12), MLFR end-to-end (FRF.15), MLFR UNI NNI (FRF.16), MLPPP (RFC 1990), and multiclass MLPPP. For more information, see Layer 2 Service Package Capabilities and Interfaces and Link Services IQ Interfaces Configuration Guidelines.

NOTE: The AS PIC II for Layer 2 Service is dedicated to supporting the Layer 2 service package only. |
For additional information about Layer 3 services, see the JUNOS Feature Guide.
