The CPU SDRAM will serve to hold things such as the Linecard's running microcode datastore and the linecard's FIB (i.e in distributed CEF operation) The Packet SDRAM will provide shared memory for packet buffers to store incoming packets from the interfaces, ready to be forwarded via a switching mechanism by the linecard processors. I believe its also used for some queuing mechanisms. Think of it as: CPU SDRAM = FIB Packet SDRAM = packets Dave. > > > > Regards, > > Masood Ahmad Shah > > > > _______________________________________________ > cisco-nsp mailing list [email protected] > https://puck.nether.net/mailman/listinfo/cisco-nsp > archive at http://puck.nether.net/pipermail/cisco-nsp/ > _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
