Configuring Chassis FPC (NSM Procedure)

For MX Series routers, there is a one-to-one mapping of the Packet Forwarding Engines and the PICs. Therefore, you can override the port-mirroring instance properties configured at the DPC level and configure a PIC-level port-mirroring instance. To bind a port-mirroring instance to a specific Packet Forwarding Engine and its associated ports, you can use this option.

You can also configure aggregate ports, maximum queue per interface, and tunneling services for PICs.

To configure chassis FPC in NSM:

  1. In the NSM navigation tree, select Device Manager > Devices.
  2. Click the Device Tree tab, and then double-click the device to select it.
  3. Click the Configuration tab. In the configuration tree, expand Chassis > Fpc.
  4. Add or modify settings as specified in Table 1.
  5. Click one:
    • OK—Saves the changes.
    • Cancel—Cancels the modifications.
