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

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

First step for all integrations¶

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

Use case 1: coworking network¶

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