[Dhikra Marghli]

Hello

I have VLAN 0 vlan managment in wlc. vlan untagged ..

so i want vlan 0 to be vlan 1 managment in wlc ...?? when i put command

config interface vlan managment 1 ===> wlc blocked and not allow me to save config !!

i need all cammand that allow vlan 0 to vlan 1 managment like the previous configuration

so  wait a reply from expert wirless that give me a answer 

thanks in advance

Vlan 1 is always untagged.  You need to define a different vlan.  

[Dhikra Marghli]

NO  , because the configuration initial is vlan 1 : vlan mangement not vlan 0 !! 

so I want vlan 1 as vlan mangment !!

how i can make it as before !!  

So please ,  i want a help for  vlan managment wlc cisco ::

thanks in advance

If you want vlan 1 as management, then your management vlan is tagged for 0.

[Dhikra Marghli]

First i configure in switch : 

interface g1/0/3  :**** conncted to wlc )

switchport trunk native vlan 0 ??? that allow me configuration vlan 1 in wlc !! or not !!  VLAN 1 : vlan for access point 

Please , Scott can you explain me to understand !!

thanks in advance

Here is how it works.... if you are using vlan 1 in your switch infrastructure, then that vlan is always untagged by default within the software.  So that would mean that your controller if using vlan 1 for management just need to add the vlan to the trunk as by default it knows vlan 1 is untagged.

If you are using an AireOS controller, then the management is 0. A 9800, is like a switch so it knows that vlan 1 is always untagged.

interface GigabitEthernet1/0/43

switchport trunk allowed vlan 1,7
switchport mode trunk

thsi configuration in switch 9200 but      when i put in wlc this command :   config interface vlan managment 1 

the wlc not allow me to save this command and is bloked !!!

it is my problem about vlan 0 to vlan 1 !!!

so if i  changed  this configuration in switch that allow me configure vlan 1 in wlc !!!??  this configuration in switch is correct or not !!! 

i wait a reply and a solution for this problem 

thanks in advance

Post your controller interface config also.

This switch port config basically means that vlan 1 is untagged and vlan 7 is tagged

interface GigabitEthernet1/0/43

switchport trunk allowed vlan 1,7
switchport mode trunk

Well it seems like the management interface can not be untagged:

Management interface VLAN tag

Cisco recommends using VLAN tagging for the management interface of the WLC. To configure the wireless management traffic to be tagged, just make sure there is no native VLAN command under the trunk configuration on the port/LAG. For example:

interface GigabitEthernet2

 switchport trunk allowed vlan 201,210,211

 switchport mode trunk

where 201 is the wireless management interface VLAN and 210 and 211 are the client VLANs. Ensure that the corresponding VLAN is allowed on the switch port as well and is tagged by the trunk (nonnative VLAN). In the above configuration, the assumption is that the native VLAN (by default this is VLAN 1) is not used.

Ok i unterstand You ... thanks to reply me

But  i want a command that i can configure in controller Cisco   interface management to be vlan 1 not vlan 0 ...!!!???

2) because before i configure in  wlc vlan 0 untagged ...it was vlan 1 

3 ) before this configuration in Switch (now )

Switchport trunk allowed vlan 1 7 

It was this configuration ( previous)

Switchport trunk allowed vlan 1 7

Switchport trunk native vlan 7

Hi,

Here is the command to configure vlan on mgmt interface: config interface vlan management 1

!

Switchport config should look like:

interface Gig x
Switchport mode trunk
Switchport trunk allowed vlan 1, 7

But above config will not work because vlan 1 is untagged.

Best case would be: Plan a different vlan for wlc mgmt and assign to WLC and swicthport.

 ok i understand   your reply ...BUT

initial state controller was connected before with Switch SMC:

config Switch SMC
interface ethernet 1/34
switchport allowed vlan add 1 untagged
switchport native vlan 1
switchport mode trunk
switchport allowed vlan add 1,7 tagged

configin  wlc with vlan 1 as vlan managment that allow pc laptop access to wlc 172.16.0.210 and  everything is fine ...

So  now , then customer wants wlc to connect to switch 9200. when I switch config SMC to switch 9200 .. wifi internet does not work either vlan 1 or vlan 0( wlc ) and you know they FW and router 

so if the permutation does not work  , he wants wlc configuration  return as start

=====>  this is problem for permutation switch SMC with switch 9200 (  the goal of working ... in the permutation all switch to switch 9200, it is necessary that all works  fine .. but unfortunately  allow internet  wifi  wifi don't work !!!

[Dhikra Marghli]

NOW  :

Vlan 0  : addres ip : 172.16.0.210 with gatway 172.16.0.1/20  : 255.255.255.240

if you assign VLAN 0 on mgmt interface of the wlc then it should work.

Switch config will look like this:

interface ethernet 1/34

switchport mode trunk
switchport trunk allowed vlan 1,7

Regarding Internet issue:

check if you can get connectivity between switch and firewall ? if not then resolve it first. 

Looks to me is alike a routing issue not wireless.
