Paraphrased from MikroTik SFP module compatibility table – MikroTik Wiki [WayBack ]:
SFP+ interface compatibility settings with 1G links For MikroTik devices with SFP+ interface that support both 10G and 1G link rate following settings are needed to be set on both linked devices for required interfaces. In order to get them working in 1G link rate.
auto-negotiation disabled
port speed 1G
FD
Devices which SFP+ ports support 1G links :
All SFP+ interfaces can be used in 1G mode if required:
Only SFP+1 supports 1G link speed, SFP+2 is for 10G links only:
Devices which SFP+ interfaces can be used only for 10G links :
Some caveats leading to the above info: CCR1036-8G-2S+ SFP Problems – MikroTik RouterOS [WayBack ]

When you want your Mikrotik DHCP Server handout different gateways (or DNS/WINS/NTP/.. servers and other settings), many of the answers tell you to fiddle with the DHCP networks like DHCP Server different gateways – MikroTik RouterOS [WayBack ] but lack concrete examples, so here we go elaborating a lot on DHCP server with static leases – MikroTik RouterOS [WayBack ]:

The locking tab of RJ45 plugs breaks very easily. Replace it by two nylon cable ties (aka zip ties), in minutes. IMPORTANT NOTES: – This must be regarded as a temporary “Mac Gyver” solution, for home usage. – Definitely not for IT staff! (no crimper? asking for one in the budget won’t get you fired!) – Before the tab breaks, consider protecting the plug.

The RouterOS scripting language you can use on Mikrotik device immediately shows it’s origin: the console.
It is a statement oriented language where statement separators can be both semicolons and new-lines.
You can use the \ at the end-of the line as line-continuation character effectively spreading statements over multiple lines.
As promised some links to questions I asked:

When switching my DHCP to a Mikrotik CCR1009, both the AP7920 and AP7921 failed to get IP addresses. The APC7921 would look bounce between waiting and offered states like this:
The cause is the need of DHCP Option 43 (Vendor Class Identifier ) specified in RFC2132 – based on [WayBack ] RFC 2131 – Dynamic Host Configuration Protocol and [WayBack ] RFC 1533 – DHCP Options and BOOTP Vendor Extensions – which I found first via these links:

The WAN sides of my Mikrotik CCR1009 are partly behind Fritz!Box routers that do NAT and contain a truckload of port-forwards.
A while ago, I wanted the CCR1009 to do PPTP as Fritz!Box 7360 and 7490: static routes over VPN don’t work (so I could only VPN to the WAN side of the CCR1009). However, it would not pass through the Fritz!Box from the outside.
It appears you need to forward both:
Maybe one day I will ditch the Fritz!Box 7490 and directly hookup the Mikrotik to the NTU: xs4all ftth en Mikrotik router – Google Groups .
But preferably I should follow Don’t use PPTP, and don’t use IPSEC-PSK either (via: CloudCracker blog)

Forward both PPTP TCP port 1723 and the GRE protocol
