Upgrade or Downgrade MPCs (MPC8E and JNP10K-LC2101)

You can upgrade MPC8E to provide an increased bandwidth of 1600 Gbps (1.6 Tbps). Similarly, you can downgrade the JNP10K-LC2101 MPC to provide a decreased bandwidth of 1.44Tbps.

Upgrade MPC8E to Provide Increased Bandwidth

In Junos OS Release 16.1R1 and later, you can upgrade MPC8E to provide an increased bandwidth of 1600 Gbps (1.6 Tbps) by using an add-on license. After you purchase the license and perform the upgrade, MPC8E provides a bandwidth of 1.6 Tbps, which is equivalent to the bandwidth that MPC9E provides. However, the MPC continues to be identified as MPC8E.

Note:

  • To check whether your platform supports the MPC8E line card, see MX2K-MPC8E.

  • After you upgrade MPC8E to provide a bandwidth of 1.6 Tbps, the power consumption by MPC8E increases and is equivalent to the power that MPC9E consumes. See MPC8E for more information.

After you purchase the add-on license, you upgrade the bandwidth by using the set chassis fpc slot bandwidth 1.6T command. You can disable this feature by using the delete chassis fpc slot bandwidth 1.6T command.

Note:

When you modify the bandwidth of MPC8E and commit the configuration, the MPC automatically reboots. For instance, if you upgrade MPC8E to provide a bandwidth of 1.6 Tbps and commit the configuration, the MPC automatically reboots. Also, if you disable the feature on MPC8E (to provide a bandwidth of 960 Gbps) and commit the configuration, the MPC automatically reboots.

Downgrade JNP10K-LC2101 to Provide Decreased Bandwidth

You can downgrade the JNP10K-LC2101 MPC to provide a decreased bandwidth of 1.44Tbps. After you perform the downgrade, JNP10K-LC2101 provides a bandwidth of 1.44Tbps. Each of the six Packet Forwarding Engines now provide a maximum bandwidth of up to 240 Gbps, which you cannot oversubscribe.

To downgrade the bandwidth, use the set chassis fpc slot bandwidth 1.44T command. You can disable this feature by using the delete chassis fpc slot bandwidth 1.44T command.

Note:

  • To check whether your platform supports the JNP10K-LC2101 line card, see JNP10K-LC2101.

  • When you modify the bandwidth of JNP10K-LC2101 and commit the configuration, the MPC automatically reboots . For instance, if you downgrade JNP10K-LC2101 to provide a bandwidth of 1.44 Tbps and commit the configuration, the MPC automatically reboots. Also, if you disable the feature on JNP10K-LC2101 (to provide a bandwidth of 2.4Tbps) and commit the configuration, the MPC automatically reboots.
