Configuring 40-Gigabit Ethernet PICs

 

You can learn about the 40-Gigabit Ethernet PICs in this topic.

40-Gigabit Ethernet PIC Overview

The 40-Gigabit Ethernet PIC with CFP (PD-1XLE-CFP) is a 1-port 40-Gigabit Ethernet Type 4 PIC with C form-factor pluggable transceiver (CFP) optics supported on T640, T1600, and T4000 routers. The 40-Gigabit Ethernet PIC occupies FPC slot 0 or 1 in the Type 4 FPC and it is similar to any regular PIC such as the 4-port 10-Gigabit Ethernet LAN/WAN PIC with XFP (PD-4XGE-XFP) PIC. The CFP information appears under the PIC information in the show command output.

The 40-Gigabit Ethernet PIC with CFP supports flexible Ethernet services encapsulation and MAC accounting.

MAC learning, MAC policing, and Layer 2 rewrite features are not supported.

The 40-Gigabit Ethernet PIC with CFP supports the following features:

  • Encapsulation protocols such as:

    • Layer 2 protocols

      • Ethernet CCC, Ethernet TCC, and Ethernet VPLS

      • VLAN CCC

      • Extended VLAN TCC

      • VLAN VPLS

      • Flexible Ethernet service

    • Layer 3 protocols

      • IPv4

      • IPv6

      • MPLS

  • CFP Multi-Source Agreement (MSA)-compliant management data input/output (MDIO) control features (transceiver dependent).

  • Graceful Routing Engine switchover (GRES) (in all PIC and chassis configurations).

  • Interface creation:

    • When the PIC is brought online, the router creates one interface, et-x/y/0, where x represents the FPC slot number and y represents PIC slot number. The physical interface represents internal Ethernet Packet Forwarding Engines.

    • The FPC slot number ranges from 0 through 7 in T640, T1600, and T4000 routers. The PIC slot numbers are 0 and 1.

    • Packet Forwarding Engine 0 is the physical interface 0, and Packet Forwarding Engine 1 is the physical interface 1.

  • 802.3 link aggregation:

    • The configuration of the 40-Gigabit Ethernet PIC with CFP complies with that of the existing 1-Gigabit or 10-Gigabit Ethernet PIC and aggregated Ethernet interfaces.

    • An aggregate bundle that consists purely of 40-Gigabit Ethernet PICs supports a maximum of 40-Gigabit Ethernet links depending on the system implementation.

For Junos OS configuration information about this PIC, see Configuring 40-Gigabit Ethernet PICs. For hardware compatibility information, see the T1600 PICs Supported topic in the T1600 Core Router Hardware Guide hardware guide and the T640 PICs Supported topic in the T640 Core Router Hardware Guide hardware guide, and the T4000 PICs Supported topic in the T4000 Core Router Hardware Guide hardware guide.

Configuring 40-Gigabit Ethernet PICs

You can configure the following features on the 40-Gigabit Ethernet PIC with CFP (PD-1XLE-CFP):

  • Flexible Ethernet services encapsulation

  • Source address MAC filtering

  • Destination address MAC filtering

  • MAC accounting for receive (Rx) and transmit (Tx)

  • Multiple tag protocol ID (TPID) support

  • Channels defined by two stacked VLAN tags

  • Channels defined by flex-vlan-tagging

  • IP service for stacked VLAN tags

  • IP service for nonstandard TPID

The following features are not supported on the 40-Gigabit Ethernet PIC with CFP:

  • MAC learning

  • MAC policing

  • Layer 2 rewrite

Note

Each 40-Gigabit Ethernet PIC with CFP creates a single et- physical interface in the Routing Engine and Packet Forwarding Engine.

The 40-Gigabit Ethernet PIC with CFP supports aggregated Ethernet configuration to achieve higher throughput capability, whereby the configuration is similar to the 1-Gigabit or 10-Gigabit aggregated Ethernet interface configuration. A maximum of 40-Gigabit Ethernet PIC links can be bundled into a single aggregated Ethernet configuration depending on the system implementation.

To configure the 40-Gigabit Ethernet PIC with CFP:

  1. Perform the media configuration.

    The command used to configure the media for the 40-Gigabit Ethernet PIC with CFP is the same as that for other Ethernet PICs, such as the 4-port 10-Gigabit Ethernet PIC.

  2. Specify the logical interfaces.

    A single physical interface is created when the 40-Gigabit Ethernet PIC with CFP is brought online (et-x/y/0, where x represents the FPC slot number and y represents the PIC slot number). For more information, see Configuring Access Mode on a Logical Interface and Configuring a Logical Interface for Trunk Mode.

  3. Configure the 802.3 link aggregation.
  4. Configure the Packet Forwarding Engine features.

    The 40-Gigabit Ethernet PIC with CFP supports all classification, firewall filters, queuing model, and rewrite functionality features of the Gigabit Ethernet PICs. To configure these parameters, see Configuring Gigabit Ethernet Policers, Configuring Gigabit Ethernet Policers, and Stacking and Rewriting Gigabit Ethernet VLAN Tags Overview.
