DIP switches? Frank -----Original Message----- From: NANOG [mailto:nanog-bounces () nanog org] On Behalf Of Saku Ytti Sent: Tuesday, June 24, 2014 3:21 AM To: nanog () nanog org Subject: Re: MACsec SFP On (2014-06-24 09:59 +0200), Pieter Hulshoff wrote: Hi Pieter,
I've seen this request from others as well. Do you have any proposal/preference to limit the data rate from the switch?
For this solution to be marketable, it needs to be extremely cheap, as you're essentially competing against cheapest consumer grade switches to subrate a port. These ports would not be revenue generating, but almost invariably MGMT ports to legacy equipment, issues like QoS are not relevant, price point is. From switch POV, packets would be lost on-link when rate exceeds, and TCP would then decrease rate. So SFP would need to implement rudimentary buffering and packet dropping. And as always, it's best if there is some way for these to work without any configuration, as the moment you need to configure 1 thing, you need to develop provisioning system and potentially also configuration backups, which may in some organizations make solution prohibitively expensive compared to using small switch from existing vendor, which is already supported by systems. -- ++ytti
