Static IP Assignment on a Cisco Meraki MX100 ports

Greetings;

I have MX100 installed and unfortunately I failed to assign a static IP to a its port.

Bellow is the topology:

How should I assign this IP 10.10.254.1 to port 3 of my Meraki MX100?

Regards;

choose under per port vlan settings the according port and push edit...in the menu you can define the vlan it should be in and if it is an access port or a trunk

Hi @rwiesmann 

 

Thank you for the quick reply;

For more information, I need to replace the existing Cisco ASA firewall by new purchase Meraki MX100.

This Cisco ASA firewall is connected to the switch with the following configs

 

FOR ASA:

 

interface GigabitEthernet0/2
  nameif inside-c1
  security-level 100
  ip address 10.10.254.1 255.255.255.248

 

 

 

FOR SWITCH

 

interface FastEthernet0/1
  description LINK TO FIREWALL
  no switchport
  ip address 10.10.254.3 255.255.255.248

 

 

Will I need to change some configs on the switch? Probably changing switchport to trunk

You dont  need a trunk. Create the  vlan and assign  the ip. Set the port to access  and assign the vlan you just created

depends on how your setup looks like...

but if you only have one vlan to the switch.

assign the vlan, the according ip address and use access

that's it

Hi @mugrene .

If you have some VLANs and you want route it from MX you need trunk, if you route the vlan from switch you don't need trunk.

 

If you have only one vlan you can use 10.10.254.1 as default gateway and use the port in the switch as switchport.

Re: Static IP Assignment on a Cisco Meraki MX100 ports

Since you are replacing an ASA with an MX, I'll just have to say this.

 

A Meraki MX100 is not a Cisco ASA firewall.

 

So don't be surprised if there is some functionality in an ASA that isn't present on an MX. I've had my fair share of rogue Sales persons, thinking an MX can simply replace an ASA, without having looked into the running configuration.

 

You can not assign an IP address to an physical interface of an MX (or any other Meraki product). So in order to obtain what you are depicting, you'll have to create a VLAN on the MX, and assign it an IP, and a SVI interface on your core switch. Just as others already have mentioned. 

 

Basically, what you are doing is, a Layer 3 topology as described in https://documentation.meraki.com/Architectures_and_Best_Practices/MX_and_MS_Basic_Recommended_Layer_...

 

Assuming you are handling DHCP somewhere else, then creating the VLAN on the MX, remember to disable the DHCP server, that is created by default.
