MS120-8P switch problem

Hi, have some questions on ms120-8p switch

1. how to set static ip address for a new ms120-8p switch? 

    connect laptop to ms120, cannot get IP address , DHCP seems not working. 

 

2. if configure two VLANs on ms120-8p, 1 VLAN is used for wan connection, and another VLAN used for LAN connection and set management IP same as one LAN VLAN (this VLAN has internet access), then ms120-8p offline in dashboard. For normal Cisco switch, there should be no problem, but ms120-8p seems network looping occurs. 

 

Please advise, thanks in advance.

Re: MS120-8P switch problem

1. The easiest way is through the dashboard. This only works if your switch can connect to the dashboard of course (using an IP address it received from a DHCP server). To do this, just claim the device using the "Organization/Inventory" page. After claiming it will show up in your "Switch/Switches" list. Just click on it and in the page that comes up just click on the small pencil next to the IP. There you'll be able to change the IP.

If it can't connect to the dashboard (for example because it needs a specific DNS server or gateway to be able to get out to the internet) you'll have to do it using the local status page:

https://documentation.meraki.com/zGeneral_Administration/Tools_and_Troubleshooting/Using_the_Cisco_M...

 

2. Not sure what you mean. The IP you set in the previous step is only relevant on the Management VLAN, which by default has id 1. Are you talking about the "Addressing & VLANs" setting in the "Security & SD-WAN" menu by any chance? That is for the MX, not for the switch. The switch can have a trunk to the MX, but it's a layer 2 switch so it will not have an IP address of its own on the VLANs.

Kind of a big deal

Re: MS120-8P switch problem

For the sake of curiosity, why do you want to use a static IP?

 

If you are trying to do it via local access, you will need to follow the guide here:

 

https://documentation.meraki.com/zGeneral_Administration/Tools_and_Troubleshooting/Using_the_Cisco_M...

 

Either go to http://switch.meraki.com

 

Or you will need to configure your computer with the following:

 

1.1.1.99

255.255.255.0

 

Then you should be able to access 1.1.1.100 (switch IP)

 

If the switch is able to reach the cloud, then you can configure it here:

What device is the MS120 connecting to? Does that device have the same VLANs?

Re: MS120-8P switch problem

Thanks for both of you kind reply. 

The MS120-8p  works as wan switch, port 1 is configured as vlan 100, and  connected to HP msa router. MS120-p port 2 is also configured to vlan 100, and connect to mx84. MS120 port 8 is configured to VLAN 200, and connected to LAN core switch one port, which is also VLAN 200. LAN vlan 200 can access internet. MS120-8p vlan 200 ip address is used to register on dashboard, but this actually not working, dashboard displays MS120-8p offline. Please advise what the possible cause. Thanks.

Re: MS120-8P switch problem

Does your VLAN200 have internet access? And if so, is the IP address for the Meraki switch behind something doing NAT?

Re: MS120-8P switch problem

In what subnet did you put the switch's IP?

 

If it's an IP in the VLAN 200 subnet, and the management VLAN on the switch is set to 1 (the default) and you don't allow VLAN 1 to cross the link to your MX (which from your description only allows VLAN 100) then the switch will not ba able to access the internet via MX84 NATing. It simply won't reach the VLAN. So change the port configuration on the MS (port 8) to allow VLAN 1 (and VLAN 1 should also be defined on the MX, which it by default is).

 

If it is in a subnet that gets NATed by the HP Router then that might work too, but then you'll have to change the management VLAN on the switch to VLAN 200.

Re: MS120-8P switch problem

yes, the core switch is behind MX84, and vlan 200 can access internet. This means that MS120 use vlan 200 as management vlan, but this configuration doesn't work properly. MS120 cannot reach internet, don't know why

Re: MS120-8P switch problem

Can you provide screenshots of how you have the local status page configured. Assuming its never actually connected to the cloud yet?

Re: MS120-8P switch problem

From the tools page of the MX, can you ping the MS? I would also look through the logs of the MX and see if you can see anything in the logs. You can filter by types or filter by the MAC address of the MS switch port.
