Port-pipes

A port pipe is a Dell Force10 specific term for the hardware path that packets follow through a system. Port

pipes travel through a collection of circuits (ASICs) built into line cards and RPMs on which various

processing events for the packets occur. One or two port pipes process traffic for a given set of physical

interfaces or a port-set. The E300 only supports one port pipe per slot. On the E1200 and E600, each slot

has two port pipes with following specifications:

48 port line rate cards have two port pipes on the line card

48 port high density cards have only one port pipe on the line card

Note: All references to the E1200 in this section include the E1200i-AC and E1200i-DC. References to

E600 include the E600i.

For the purposes of diagnostics, the major difference between the E-Series platforms is the number of port

pipes per slot.

E1200 and E600—Each slot has two port-pipes. Each portpipe has nine 3.125Gbps channels to the

backplane, one to each SFM.

E300—Each slot has one portpipe. Each port-pipe has eight 3.125Gbps channels to the backplane,

with four channels to each SFM.
