(MAC)s and Physical Layer Controls (PHY)s as well as the physical
interfaces for direct network connections. A single PIM interconnects with
a single DPM to form a Ethernet Routing Switch 8600 module. modules
with DPMs are R modules.
Ethernet Routing Switch 8600 modules which use the BFM are pre-E, E,
or M modules. These modules are described in,
8600 modules (Release 3.x feature set)" (page
Each DPM contains either two or three lanes depending on the module.
Both the 8630GBR and the 8683XLR modules consist of three lanes.
The 8648GTR module consists of two lanes. Each lane is also known as
a Flexible Forwarding Engine (FFE). The FFE lane is the basis for the
Ethernet Routing Switch 8600 R modules. The FFE lane consists of:

The ingress RSP2 executes lookups, performs filtering and classification
operations, and modifies the IP and MAC headers within the body of the
packet to reflect routing and switching decisions.
