      I point my Linksys switches to pfSense and it just works.

        That seems to work, apparently for IPv4 only though. Still better than nothing, though it seems strange on a box that otherwise supports IPv6. Is that a bug in SNTP or the switch?

          You do see he is syncing via IPv6.. You can clearly setup IPv6 sntp in the switch firmware... What firmware are you using for sg200?

          1.4.10.06
          Is the latest that is the same as my sg300, does your switch have an IPv6 address?

            Mine's 1.0.6.2. When I provide my NTP server (pfSense) host name, it resolves to the IPv4 address. The manual IP config only allows IPv4. I'll have to see about the update. Yes, it does use IPv6 for the management interface. It even has an IPv6 neighbours table.

              I don't even see that listed on the cisco site... got to be ancient...
              edit: Oh I found it 27-Feb-2013, so 6 years old ;)
              Did they even have any ipv6 in those old firmwares?

              Yeah I would update... current for sg200 is 1.4.10.06, just recently came out... I have both my sg300 running it.

              edit: Here I just added ipv6 to my sg300, bing bang zoom he syncing sntp with ntp running on pfsense via ipv6

              He is going to use the pi on 3.32 since that is stratum 1, but wanted to point to pfsense ntp which is stratum 2.. But as you can see talking just fine to it.. And getting time.

                Is there some incantation to the network gods needed to update? I've downloaded the latest from April 29, and select the file, click on apply and nothing happens. The help(?) seems to imply a TFTP or HTTP server may be needed, but there's no way to enter a URL for HTTP. I guess I'll have to set up a TFTP server. It's been a while since I've done that.

                        So you don't have the gui eanbled? To update the firmware you can just use the gui.

                          I do have the GUI enabled, but that method doesn't work. It also doesn't support HTTPS or SCP. I'm slowing getting there. I've had to do 3 updates to get this far. Apparently, there are different file types for different versions. It you don't have the correct version to upload the next it will fail. You'd think they might have an upgrade path described somewhere. Right now I'm at 1.0.8.3 and when trying to update to 1.4.10.06 it fails with "Firmware Image download through TFTP failed." Those are the two versions listed on the update page I'm looking at now.

                            I did some more digging and found 1.0.8.3 is the latest version for the 8 port model. ☹

                            It does not support IPv6 for SNTP.

                              Bring it back to the National Museum of Ancient Technologies. It was probably 'borrowed' from there anyway.

                                    On one of the support forums. I saw that link with the 2 packages. 1.0.8.3 installs, 1.4.10.06 doesn't. Apparently the issue has to do with memory size and the fact that the package now includes the boot code. If you check the downloads, you'll see they have a different file type and my switch will not accept the new file type. I have the SG200-08.

                                      Yeah I think that is E switch, because its not listed on the release notes for the 1.4.10.6 or even previous models..

                                      That firmware is quite old

                                      When did you buy this switch? Can you return it? There are much better deals out there I am sure..

                                        I bought it yesterday. I got it at a consumer level store that's known for low prices, likely because the stock tends to be older.

                                          Well if you want ipv6 and firmware that is not 5 years old.. You prob want to look for different model ;)

                                            I'm not too worried about IPv6 vs IPv4 for SNTP. Even with pfSense, the NTP servers I use support IPv4 only. However, I bought it so that I would have a managed Gb switch and that's what it does. I have the same situation with my TP-Link access point. The management is IPv4 only, but it passes IPv6 as needed, other than the previously mentioned issue that prevents me from running a 2nd SSID.
