h2. Setting up a newly arrived Mikrotik switch

This part is specific for mikrotik-crs326 devices and should

After arriving within 1 work day do:

* Unpack

* Find out which name the switch should have

** go to https://netbox.ungleich.ch

** search for crs326

** identify the last used number

** Create a new device

*** go to devices 

*** devices

*** add

**** name: "mikrotik-crs326-XX"

**** device-role: a device role

**** device-type: CRS326

**** serial-number: <from the device>

**** site: placeX -

**** create

* Add a physical label with its name

** Do not continue before you have done that!

* configure your notebook with the ipv4 address 192.168.88.23/24 

* connect to the crs326: @ssh admin@192.168.88.1@

* Configure the switch

** Set identity: @/system identity set name=mikrotik-crs326-XX@ # use the correct name

** Set password: @/user set admin password=@ # use the password for mikrotik in the place that you are, use password store

** Enable IPv6: @/system package enable ipv6@

** Reboot so that IPv6 is enabled: @/system reboot@

** Add a place indendent, unrouted IPv6 address: @/ipv6 address add eui-64=yes advertise=no interface=bridge address=2a0a:e5c0:1:c::/64@

** Get the assigned IPv6 address: @/ipv6 address print@

** Disconnect from the switch

* Assign your notebook the IPv6 address *2a0a:e5c0:1:c::23/64*

* Connect to the switch via IPv6

** Remove the IPv4 address 192.168.88.1 to avoid collisions with other switches: @/ip address remove numbers=0@

*** Verify: @/ip address print@

* Verify / update entries in netbox:

** Verify that the serial number is correct: @:put [ /system routerboard get serial-number ]@

** Netbox

*** go to the ipv6 prefix https://netbox.ungleich.ch/ipam/prefixes/216/

**** create a new ipv6 address

**** set the DNS name to *mikrotik-crs326-XX*

**** role = loopback

* Ensure all steps are taken correctly

* Move the device to our inventory / stock if not directly used

h2. Configuring a Mikrotik switch for integration into the network

Depending on the usage scenario, we will define a variety of bridges and assign ports to it.

* In almost all cases the uplink port will be the *sfp-sfpplus1* port.

* In almost all cases we want to apply vlan tagging to that port

* For server networks, we configure the MTU to the highest value the switch supports

** Devices are configured with a 9200 MTU

** So the MTU on the switch ports needs to be at least 9200

h3. First step for all integrations

* Setup MTU of the *sfp-sfpplus* ports (plural)

h3. Use case 1: coworking network

To use the switch in a coworking network, we keep the MTU
