View Fiber SFP details in Mikoritk RouterOS

Quick and simple way to check the details on a fiber SFP on a Mikrotik router. Replace sfp1_name with the SFP name or leave out the name and select a number.

/interface ethernet monitor "sfp1_name"


                      name: sfp1
                    status: link-ok

        sfp-module-present: yes
               sfp-rx-loss: no
                  sfp-type: SFP-or-SFP+
        sfp-connector-type: LC
       sfp-link-length-9um: 3000m

Configure SNMPv3 on Cisco Router

How to configure SNMP v3 on Cisco Switch, Router, ASA, Nexus (

Enter configuration mode

conf t

Everything in bold you should look at changing.

snmp-server view ViewDefault iso include
snmp-server group GroupName v3 priv read ViewDefault
snmp-server location address
snmp-server user MyUsername GroupName v3 auth sha AuthPass1 priv aes 128 PrivPass

Exit and save changes


Now we can verify the snmp details with

show snmp

Simple OSPF between Mikrotik Routers

Setting up OSPF between Mikrotik routers is not too difficult. The following commands should work with RouterOS version 7+. Run these commands on each Mikrotik changing out the router-id.

Create a Loop-back interface

First it would be a good idea to create an loopback interface that will stay up. We’ll use this address as the router-id. This should be unique per router.

/interface/bridge/add name=loopback
/ip/address/add address= interface=loopback

Now lets setup OSPF.

Create OSPF Instance

First we’ll create the instance. Use the address from the above loopback address. Technically you can use whatever id you want as long as it is a 32 bit “address” and is unique.

/routing/ospf/instance/add name=default router-id=

IMPORTANT NOTE: If this router is also the default gateway, you’ll need to specify the “originate-default=always” option to share the default gateway over OSPF to the other routers. You don’t have to do this if you don’t want to share the default route.

Create OSPF Area

Now we can create an OSPF area. For a simple OSPF setup, we’ll just use the default area.

routing/ospf/area/ add name=default area-id= instance=default

Create Instance

Now we can add an instance. This is responsible for what networks get shared with OSPF. If you want to do all the addresses on the router, then use If you only want to do specific networks, run an entry for every network, changing to the network of interest.

/routing/ospf/interface-template/add networks= area=default

Wrapping Up

After that we can check to make sure things worked.


You should see at a neighbor. It can take a little bit for the neighbors to show up.

You can also check the routes on the router.


OSPF has a default distance of 110, so checking the routes is a quick way to verify the routes are getting updated. Do note that if you have a static route in with a lower distance, that will take precedence over OSPF.
