This RouterOS script will check the existing vlans, check to see which vlans are missing, and then add those specific vlans to the interface required.

I used this to deploy vlans to our CCR routers for our 12 site enterprise. It uses key:value arrays for the vlans.


Code: Select all

###This Script will auto create vlans that are missing 
###Add the vlans you need to have in the newVlanArray variable by using "vlanid"="vlanName" and the script will do the rest
###BOF###
##Initialize variables

:global "physInterface" ether1;
:global "newVlanArray" {"104"="104-MGMT";"116"="116-security";"152"="152-pcdata";"160"="160-printers";"168"="168-voice";"176"="176-wireless"};
:global "oldVlanArray" [/interface vlan find];
:global "COUNTER1" 0;

##DO NOT CHANGE ANYTHING ELSE BELOW##
###
###
#Functions
#Create function to add all the vlans to the router

##
#Create Function to add a single vlan
:global "AddSingleVlan" do={
    /interface vlan add interface=$1 name=$2 vlan-id=$3;
    :put "VLAN $2 has been added";
}
###
:global "AddAllVlans" do={
    :foreach k,v in=$newVlanArray do={
    $AddSingleVlan $physInterface $v $k
    }

}

#Backup Router using Binary Backup
#Check to see if there are any vlans on router.  If not, add all vlans
#If vlans exists, check to see if each one exists and create the ones that do not
system backup save dont-encrypt=yes name=BeforeVlans
:delay 5

:if ([:len $oldVlanArray] < 1) do={
    :put "No Vlans are on this router";
    $AddAllVlans;
    :put "All New Vlans are now added";
} else={
    :put "VLANS exist, checking each one"
    :foreach k,v in=$newVlanArray do={
        :global newvlanid $k
        :global newvlanname $v
        :set "COUNTER1" 0
        :foreach item in=$oldVlanArray do={
            :global oldvlanname [/interface vlan get value-name=name number=$item]
            :global oldvlanid [/interface vlan get value-name=vlan-id number=$item]
            :if ($oldvlanid !=$k) do={:set "COUNTER1" ($COUNTER1 +1)}}
        :if ($COUNTER1 = [:len $oldVlanArray]) do={$AddSingleVlan $physInterface $newvlanname $newvlanid}
    }
}
:put "FINISHED ADDING VLANS"
