Agreed! All switch/FW/routers have the ability/feature in either CLI or GUI, so I guess that I was just wondering why it wasn't part of pfS.
I agree on most point you make and there are "those" out there that have and will continue to bungle connectivity with setting S/D incorrectly, but why not make it available (wo/ editing the XML) for those of us that know how and when to use it? Every single Cisco, Juniper, Foundry engineer I know (or I've taken advanced seminars from) has stringently recommended the use of static S/D settings on edge routers and core switching. Given that I did some asking around and googling and it seems that Cisco at least has changed their view in recent years on their S/D philosophy .... ==SNIP== Recommended Port Configuration (Autonegotiation or Manual Configuration) There are many opinions on the subject of autonegotiation. Previously, many engineers advised customers not to use autonegotiation with any switch-connected device. However, improvements in the interoperation of autonegotiation and the maturity of the technology has recently changed the view of autonegotiation and its use. In addition, performance issues due to duplex mismatches, caused by the manual setting of speed and duplex on only one link partner, are more common. Because of these recent issues, the use of autonegotiation is regarded as a valid practice. ==SNIP== Source -> http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00800a7af0.shtml I totally understand that it presents many, many threads of list chatter when it comes to bite someone who doesn't understand the ramifications of the settings, but none the less, I feel it is a valuable configuration setting for the great "enterprise ready" product you've all put forth, and for those among us that use this setup and know it!!!!
