Graceful Routing Engine Switchover PIC Support

Graceful Routing Engine switchover is supported on most PICs, except for the services PICs listed in this section. The PIC must be on a supported routing platform running the appropriate version of JUNOS software. For information about FPC types, FPC/PIC compatibility, and the initial JUNOS software release in which an FPC supported a particular PIC, see the PIC guide for your router platform.

The following constraints apply to graceful Routing Engine switchover support for services PICs:

• You can include the graceful-switchover statement at the [edit chassis redundancy] hierarchy level on a router with Adaptive Services and MultiServices PICs configured on it and issue the commit command. The commit does succeed. However, all services on these PICs are reset during a switchover.
• Graceful Routing Engine switchover is not supported on any Monitoring Services PICs or Multilink Services PICs. If you include the graceful-switchover statement at the [edit chassis redundancy] hierarchy level on a router with either of these PIC types configured on it and issue the commit command, the commit fails.
• Graceful Routing Engine switchover is not supported on Multiservices 400 PICs configured for monitoring services applications. If you include the graceful-switchover statement, the commit fails.

Note: When an unsupported PIC is online, you cannot enable graceful Routing Engine switchover. If graceful Routing Engine switchover is already enabled, an unsupported PIC cannot come online.
