Do you have a good link. I would like to know more. Thanks. Why such a change from the PFC1/MSFC1. The concept you describe below seems to be a big change. I knew there were intergrating but I could still define the seperation between router and switch with the PFC1/MSFC1. GOTTA BE ON YOUR Ps and Qs or you get left behind.
Thats why I love this job! -----Original Message----- From: Bob Sinclair [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 18, 2003 9:17 AM To: Newell Ryan D SrA 18 CS/SCBT; [EMAIL PROTECTED] Subject: Re: CEF on 6500 and ACLs [7:63175] Some comments in-line. It is becoming (has become?) very difficult if not impossible to tease out the "switch" from the "router" with PFC2/MSFC2. This box has the functions of both, and they are integrated in the hardware. For example, the Layer 2 switching engine, the Qos engine and the ACL engine are combined in the Lyra ASIC. > With CEF (PFC 2) if there is an adjacency for the destination host, to my > understanding, that packet will never be routed.
