Fortigate

Create a new Interface under a port or an existing virtual switch where the Aruba switch uplinks to 

Enter Vlan ID and Interface IP

 

Next you will need to setup Allow Policies to allow traffic from the Vlan to the normal lan as well as internet

Aruba

Create a New Vlan with the Same ID

Add a trunk to the Uplink

Tag all the Ports with Vlan 2 that will have a phone plugged into them, Including the Trunk

Untag any ports the phone system or VOIP card might use

Attach the “voice” to the Vlan which will assign the right vlans for the phones that use LLDP

Meraki MX Router

Enable Vlans

Go to Security Appliance then Addressing & VLANs

Next setup the Subnet ID ( Number ) for your Vlans and the Address of the Router in each Vlan 

Next Change the Uplink to the Switch to a VLAN and set the Native Vlan ( this is the default usually 1 ) and the other Vlans which will pass down this trunk. The Native VLAN will need to be the same on both sides of Meraki and Cisco Switch

DHCP

Go to Security Appliance then DHCP

What device will be the DHCP on this new Subnet? You can set the Meraki or if its a Windows Network point the IP Helper to your main DHCP server

Cisco Switch

Uplink

On the uplink of your switch to the Meraki set e.g. GigabitEthernet1/0/1

 

conf t
int gi1/0/1
switchport trunk native vlan 1
switchport trunk allowed vlan 1,5
switchport mode trunk
end

You might see the native vlan 1 not showing in the config , this is because 1 is always the native vlan

UnTag Port on new Vlan

This changes the port to use Vlan 5

conf t
int gi1/0/2
switchport acccess vlan 5
switchport mode access
end

Finding issues in wireless networks can be hard , however there are some tools you can use before you get the Spectrum Analyser in! 

Auditing

Download and install inSSIDer Home

Great way to visualise SSID strength and channels, just to note when you run this , your Pings will go up!

Ekahau

Great Heatmapping software and paid for software for scanning

How to check to DeAuths 

Once you identify the channel, launch https://www.wireshark.org/ on that channel and listen for a minute or two.

First, apply this filter:

wlan.fc.type_subtype == 0xc

This will show you all the deauthentication frames that have been sent out.

Deauth Flood

Apply this filter next:

wlan.fc.type_subtype == 0x8 && wlan.sa == <BSSID of the SSID you are inspecting>

This will display beacon frames from your AP. Check the signal strength. In this case, we’ve got a good strong signal because we’re right next to the AP (right around -40 dBm on average).

Our Beacons

Next, apply this filter:

wlan.fc.type_subtype == 0xc && wlan.sa == <BSSID of the SSID you are inspecting>

This shows deauthentication frames from your AP. Note the signal strength on the far right…

Spoofed Deauths

The deauthentication frames are coming in much weaker than the valid beacon frames. This indicates strongly that another AP is spoofing your system.

Connect to http://wired.meraki.com/#configure on a PC/Server connect to the meraki. The default username is the serial number of the device which can be got from the Cloud Dashboard and password is blank

The following will restart the Meraki so make sure you arrange downtime.

Change Port 2 to Internet from LAN and add the IP details and click Save

Make sure all ethernets are set to Auto for Negotiation

By default the Meraki will put the connections on Active / Passive , to enable Active / Active 

Login to your Meraki Cloud Dashboard and Enable Load Balancing : 

This will spread both inbound and outbound via both links

To force one port e.g. to a specific Link , add an Internet Traffic Flow setting

Get Model Number and Serial for Firmware

Login to your switch via SSH and run 

show switch

This will show you the System Type ( Model of the switch ) and if its stacked, now type 

show version

This will show you your current firmware and Also Serial Number ( In Red ) 

Download Firmware

1. Go to Extremenetwork Support and Click Downloads for ExtremeXOS for your switch model
2. Login using your account. You have to register if you don’t have account.
3. Click Accept All.
4. Type the serial number.
5. Click Software Downloads.
6. Click the correct ExtremeXOS image and download to your tftp server.

Setup TFTP

Free tftp tools such as tftp32 will work for the switch upgrade

Make sure Port UDP 69 is allowed through Windows Firewall

Even if your windows Firewall is disabled , make sure its disabled on Guest Networks as this will usually be the network the management speaks on not domain

Make sure the machine you are using does not have WDS enabled , WDS uses TFTP 

Run TFTP and make sure the server is listening on an Network IP ( NOT 172.0.0.1 )

Copy the .xos file to the TFTP Directory 

In SSH make sure you can Ping the IP of the TFTP server from the Switch via

ping %IP OF TFTPServer% 

And you get a reply 

Backup Existing Config

upload config %IP OF TFTPServer% config.xsf VR-Default

Download and install new Image

download image %IP OF TFTPServer%  summitX-22.3.1.4-patch1-8.xos “VR-Default” secondary\

Do you want to install image after downloading? (y – yes, n – no, – cancel) Yes

You will need to reboot the switch and if the switch is in a stack you will need to reboot them both as Stack switches cannot be in different versions
