Single wireless network(SSID) to broadcast on 2.4Ghz and 5Ghz radio

[uuganbat.a]

Hi, I have CISCO 1602 standalone access point, which has 2.4 and 5 radio and support to run on both radios. And I am trying to setup the two SSID, but first SSID to operate on both 2.4Ghz and 5Ghz radio, and second SSID to operate only on 2.4Ghz radio.

Is it possible to setup an SSID to operate on both 2.4Ghz and 5Ghz radio? Following are the config that I can think of, but not sure if it correct or not? Thank you.

Dot11 ssid one
Vlan 1
authentication open 
authentication key-management wpa
guest-mode
wpa-psk ascii 7
Mbssid Guest-mode
End
 
 
Dot11 ssid two
Vlan 2
authentication open 
authentication key-management wpa
guest-mode
wpa-psk ascii 7


Mbssid Guest-mode
End

Int dot11 0
Mbssid
ssid one
ssid two
encryption vlan 1 mode ciphers aes-ccm 
encryption vlan 2 mode ciphers aes-ccm 



Int dot11 1
Mbssid
ssid one

encryption vlan 1 mode ciphers aes-ccm 


interface Dot11Radio0.1

encapsulation dot1Q 1 native
bridge group 1

interface Dot11Radio1.1
encapsulation dot1Q 1 native
bridge group 1
 
interface FastEthernet0.1
bridge group 1
encapsulation dot1Q 1 native

 
interface Dot11Radio0.2
encapsulation dot1Q 2
bridge group 2
 
interface FastEthernet0.2
bridge group 2
encapsulation dot1Q 2

Hi Stephen, Basically following command will turn on the SSID on 5Ghz radio? Is there any issues if you ran same SSID on both radio?

interface Dot11Radio1.1
encapsulation dot1Q 1 native
bridge group 1

How 802.11a/b/g/n capable wireless clients choose the band, will they flap between 2.4 and 5 band?

[Stephen Rodriguez]

the bridging commands just allow the traffic to flow in the appropriate VLAN.

What allows the SSID under the Dot11Radio 1 is

ssid < blah >

that is what tells the radio what SSID to service.

As for how the client, it will choose by RSSI/SNR and what ever magic the vendor has used to determine which frequency to join.

HTH,
Steve
