Upgrading or Downgrading 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.

Upgrading MPC8E to Provide Increased Bandwidth

In Junos OS Release 15.1F5 and later, MX2020 and MX2010 routers support MPC8E (model number: MX2K-MPC8E), a new Modular Port Concentrator (MPC) with two Modular Interface Card (MIC) slots that provide a maximum bandwidth of 960 Gbps. . Each MIC slot on MPC8E supports a 12-port rate selectable MIC (MIC-MRATE). MPC8E has four Packet Forwarding Engines, each providing a maximum bandwidth of 240 Gbps.

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

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.

Downgrading JNP10K-LC2101 to Provide Decreased Bandwidth

In Junos OS Release 18.2R1 and later, MX10008 routers support the JNP10K-LC2101 line card. The JNP10K-LC2101 is a fixed-configuration MPC that provides increased port density and performance to the MX10008 routers. JNP10K-LC2101 does not contain separate slots for Modular Interface Cards (MICs). MX10008 routers support eight JNP10K-LC2101 MPCs. By default, each JNP10K-LC2101 MPC provides a maximum bandwidth of 2.4Tbps. JNP10K-LC2101 has six Packet Forwarding Engines, each providing a maximum bandwidth of up to 400 Gbps, which cannot be oversubscribed.

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 cannot be oversubscribed.

You can downgrade the bandwidth by using 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

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.
