Make Roaming In Office with E400

Hi,
I have router and 2 E400

Need create one LAN for office.

 

So I put each E400 in different places and connect via wire to router.

 

Router has DHCP network 192.168.1.0/255.255.255.0 (With own IP 192.168.1.1)
E400 - 1 has static IP( based on MAC) 192.168.1.2
E400 - 2 has static IP( based on MAC) 192.168.1.3

 

Both AP has same settings except
Hostname
Wireless ridio channel (E400 - 1 has 1 on 2GHz and 36 on 5GHz, E400 - 2 has 6 on 2GHz and 48 on 5GHz)

 

But when I transfer device from one AP to another ping drop 3 - 4 packet.

Both AP in the same network 192.168.1.0/255.255.255.0

Wireles wlan has same name and password

Also roaming is enabled:

fast-roaming okc

fast-roaming 802.11r

fast-roaming 802.11r reassociation-timeout 20

band both

band-steer normal

 

Also i have question - How I can make acces from devices on AP1 to devices on AP2?

(For example printers is availeble only for devices on the same AP)

Re: Make Roaming In Office with E400

1) Devices form AP2 on VLAN 20 (WiFi - WORK with 192.168.2.1 and DHCP 192.168.2.2-254) can't access

the device (in my case it is Printer with static IP 192.168.2.100) on AP1 on VLAN 20 (WiFi - WORK with 192.168.2.1 and DHCP 192.168.2.2-254) . What setting I need change for working fine?

 

2) When device transfer from AP1 to AP2 - what IP it will get (Same as on prev AP or new)?

If the same - what about situation When device on AP1 get IP ..2.10 and another device on AP2 got same IP.

After Device transfer to another AP - IP used.

 

3) About roaming fail - I'll try on another device and if issue present - will send you techsupport file.

Hi Sindar,

Below is the idle 802.11r roaming/OKC setup and configuration

1) Configuration on AP's in the network should be same

2) Access points should be in same VLAN / Network

3) If you are using external DHCP server then clients will retain the same IP address after roaming to new AP

4) It is not recommended to use internal DHCP server(DHCP server configured on AP)

5) All clients doesn't support 802.11r roaming, so please enable OKC based roaming if you are using 11r not supported clients


Thanks,

Re: Make Roaming In Office with E400

So If I need few VLAN (Work guest etc)

I need buy head router with VLAN support and make DHCP and VLAN settings on it, not on E400 AP?

Re: Make Roaming In Office with E400

Hi,

What type of router do you have? You can run dhcp server on one of the ap.

The set up should be below if you want multiple Vlan support. Below is the set up if you need routing between two separate vlans

 

 

router(gateway ip for Vlan 10,20)- trunk------switch (manage switch which supports mutiple vlan)--------ap1(running dhcp server)                                                             |-----------------------------------------------------------ap2                                                                        

                                                                                     

 

1) Configure L3 interfaces for those VLANs that you want. Suppose  Vlans are 10, 20 , 30

2) Configure dhcp  pool for those VLANs on ap1. keep gateway in those pool as router ip. 

3) Configure eth1 as trunk port and allow VLANs 

4) Configure trunk port in switch and allow VLANs there as well. 

5) Connect your router to the switch.

If you have L2/L3 switch then you don't need any separate router .You can configure your switch to do intervlan routing.

Re: Make Roaming In Office with E400

Thank you, now it's ok with external DHCP.

 

I have connect devices to cnMaestro.

Create AP Groups an WiFi template.

 

How I can manage different AP name or different channels for different AP  in Group Template?

I can put custom values in User Difined Overrides but I can't found if-else logic in documentation

 

for example

{%if %{MSN} == 'SOME_SERIAL_NUMBER' %}

hostname = MYHOSTNAME

{% endif %}

Re: Make Roaming In Office with E400

Hi Sindar, 

 

Group template configuration will not change the AP name.

Ex:- Before group template config push AP name was "E400-001122" after config push also AP retains the same name. 

If you want to assign different name for different AP's you have a option to do that, below are the steps to change AP name from CnMaestro

1)  Goto CnMaestro and select the device 

2) Click On Configuration and change the AP name under "Device Details" and do "Apply Configuration" to take configuration effect.

Re: Make Roaming In Office with E400

Hi Sindar, 

 

Thanks for sharing the logs. From the logs i can see many clients are connected to this AP and client(34-36-3B-5C-08-16) is disconnected due to Inactivity timer,by default inactivity timer is 1800sec means when there is no any data from the client for 1800sec the AP will sent the deauth. 

 

Thanks,
