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:
- 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.
- 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 a Logical Interface for Access Mode and Configuring a Logical Interface for Trunk Mode.
- Configure the 802.3 link aggregation.
- You must explicitly configure an aggregated interface on the 40-Gigabit Ethernet PIC with CFP that includes the 40-Gigabit Ethernet interfaces. For more information, see Configuring an Aggregated Ethernet Interface.
- The configuration of the 40-Gigabit Ethernet PIC with CFP complies with the configuration of the 1-Gigabit Ethernet PIC, 10-Gigabit Ethernet PIC, and the aggregated Ethernet interfaces. In each aggregated bundle, Junos OS supports a maximum of 40-Gigabit Ethernet links. For more information, see Configuring an Aggregated Ethernet Interface and 10-port 10-Gigabit Ethernet LAN/WAN PIC Overview.
- 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 MAC Address Filtering, and Stacking and Rewriting Gigabit Ethernet VLAN Tags Overview.
