Flexible Queuing Mode Overview

 

The queuing component on non-HQoS MPCs is disabled by default to save power. When flexible queuing is enabled on a non-HQoS MPC, the MPC is restarted with the queuing component enabled. The MPC is powered on only if the PEM has sufficient power to bring up the MPC with the queuing component enabled. The MPC remains offline if the required power is not available.

You can enable flexible queuing on the non-HQoS MPCs by including the flexible-queuing-mode statement at the [edit chassis fpc] hierarchy level. When queuing is configured, the power consumed by the queuing components at the configured ambient temperature is considered when power is allocated for the MPC.

Note

The following MICs are supported on non-HQoS MPCs only when flexible queuing is enabled:

  • MIC-3D-8CHOC3-4CHOC12

  • MIC-3D-4CHOC3-2CHOC12

  • MIC-4COC3-2COC12-G

  • MIC-2COC3-1COC12-G

Table 1 lists the MPCs that support flexible queueing and the supported Junos OS release for these MPCs.
