Enabling Inline Service Interfaces
The inline service interface is a virtual physical interface that resides on the Packet Forwarding Engine. This si interface, referred to as an anchor interface, makes it possible to provide L2TP services without a special services PIC. The inline service interface is supported only by MPCs on MX Series routers. Four inline service interfaces are configurable per MPC-occupied chassis slot.
 | Note: On MX80 routers, you can configure only four inline services physical interfaces as anchor interfaces for L2TP LNS sessions: si-1/0/0, si-1/1/0, si-1/2/0, and si-1/3/0. You cannot configure si-0/0/0 for this purpose on MX80 routers. |
To enable inline service interfaces:
- Access an MPC-occupied slot and the PIC where the interface
is to be enabled.[edit chassis]user@host# edit fpc slot-number pic number
- Enable the interface and specify the amount of bandwidth
reserved on each Packet Forwarding Engine for tunnel traffic using
inline services.[edit chassis fpc slot-number pic number]user@host# set inline-services bandwidth (1g | 10g)
