forwards the packets to either Packet Forwarding Engine 0 or Packet Forwarding Engine<br />

1. When the PIC sends out a packet, the multicast bit is set based on the egress Packet<br />

Forwarding Engine number (0 or 1).<br />

The default packet steering mode for PD-1CE-CFP-FPC4 is SA multicast bit mode. No<br />

SA multicast configuration is required to enable this mode.<br />

PD-1CE-CFP-FPC4 uses two 50 Gpbs Packet Forwarding Engines to achieve 100 Gbps<br />

throughput. The 50-Gigabit <strong>Ethernet</strong> physical interfaces are created when the 100-Gigabit<br />

<strong>Ethernet</strong> PIC is plugged in. The two physical interfaces are visible and configuration is<br />

allowed on both the physical interfaces. You must configure the physical interfaces on<br />

PD-1CE-CFP-FPC4 in static link aggregation group (LAG) mode without enabling Link<br />

Aggregation Control Protocol (LACP). This ensures that a single 100-Gigabit aggregated<br />

interface is visible on the link connecting to the 100-Gigabit <strong>Ethernet</strong> PIC PF-1CGE-CFP<br />

instead of two independent 50-Gigabit <strong>Ethernet</strong> interfaces.<br />

•<br />

NOTE: If you try to enable the interoperability between the 100-Gigabit<br />

<strong>Ethernet</strong> PICs PD-1CE-CFP-FPC4 and PF-1CGE-CFP without configuring<br />

PD-1CE-CFP-FPC4 (with two 50-Gigabit <strong>Ethernet</strong> interfaces) in static LAG<br />

mode, then there are issues in forwarding or routing protocols. For example,<br />

if you create two untagged logical interfaces—one each on the two 50-Gigabit<br />

<strong>Ethernet</strong> interfaces—on PD-1CE-CFP-FPC4 and one untagged logical interface<br />

on PF-1CGE-CFP, then PF-1CGE-CFP does not learn about one of the<br />

50-Gigabit <strong>Ethernet</strong> interfaces on PD-1CE-CFP-FPC4.<br />

You can enable interoperability between the 100-Gigabit <strong>Ethernet</strong> PICs PD-1CE-CFP-FPC4<br />

and PF-1CGE-CFP by performing the following tasks:<br />

• Configuring SA Multicast Bit Steering Mode on the 100-Gigabit <strong>Ethernet</strong> PIC<br />
