Configuring Hyper Mode on Enhanced MPCs to Speed Up Packet Processing

Starting with Junos OS Release 15.1, enhanced MPCs can be configured to support increased packet processing rates. Enhanced MPCs include these models: MPC3E, MPC4E, MPC5E, MPC6E,MPC7E-MRATE, MPC7E-10G, MX2K-MPC8E, and MX2K-MPC9E.

Starting with Junos OS Release 18.2R1, JNP10K-LC2101 MPC can be configured to support increased packet processing rates.A higher rate of processing of data packets results in the optimization of the lifetime of a data packet. Optimization of the data packet lifetime enables the network device (a router or a switch) to provide better performance and throughput.

To configure the device to support increased packet processing rates, you must configure the hyper mode feature. After configuring the hyper mode feature, you must reboot the device for the changes to take effect. If the hyper mode feature is not configured, the device processes data packets in normal mode.

Note:

You can enable the hyper mode feature only if the network-service mode on the device is configured as either enhanced-ip or enhanced-ethernet.

To configure hyper mode on enhanced MPCs to speed up packet processing:

  1. Configure hyper mode by including the forwarding-options hyper-mode statement at the [edit] hierarchy level.
  2. After configuring hyper mode, commit the configuration.
    Note:

    After configuring hyper mode and committing the configuration, the configured mode changes to hyper-mode but the current mode remains as normal mode. The device displays the following warning message after you commit the configuration:[edit forwarding-options] ’hyper-mode’ WARNING: forwarding-options hyper-mode configuration changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete

    When hyper-mode configuration is enabled on MX960 devices and reboot is performed, the backup routing engine might not come back up in correct mode.

    To recover the backup RE, perform commit force, to get the same configuration as the master routing engine. However, to get the enhanced IP configuration on the backup routing engine for the network services, after syncing the script, perform reboot using the command request routing-engine login other-routing-engine. Now both the routing engines will come up in enhanced IP mode.

  3. Reboot the device for the configuration to take effect.
