Hello.
Can you help me please.
I have in the same switch WS-C2960S-24PS-L (12.2(55)SE5) one WLC with 3 EP like that :
* Port Gi1/0/24 : WLC 2406 (7.0.220.0) port1
* Port Gi1/0/4 : EP AIR-LAP1142N-E-K9
* Port Gi1/0/7 : EP AIR-LAP1142N-E-K9
* Port Gi1/0/17 : EP AIR-LAP1142N-E-K9
* Port Gi1/0/11 : EP AIR-LAP1142N-E-K9
When I do the command show log | include flap I have that :
May 2 16:34:36.840: %SW_MATM-4-MACFLAP_NOTIF: Host 843a.4b4c.edc4 in vlan 1 is flapping between port Gi1/0/7 and port Gi1/0/11

I have flapping between my WLC and EP or between 2 EP also.
I don't know where is my error.
I have 2 networks (corp vlan 1 and guest vlan 20 ) it's why I have in my switch port 24, 4, 7 ,17 and 11 this configure :
Configure swith |
---|
interface GigabitEthernetx/0/4 switchport mode trunk ! |
In WLC :
* I have configure theses 3 EP in HREP mode.
* I have check the box in my WLAN : H-REAP Local Switching
When I enter the command
(Cisco Controller) >show interface summary
Interface Name Port Vlan Id IP Address Type Ap Mgr Guest
-------------------------------- ---- -------- --------------- ------- ------ -----
ap-manager 1 untagged 172.16.39.219 Static Yes No
guest 1 20 10.149.2.247 Dynamic No No
management 1 untagged 172.16.39.218 Static No No
virtual N/A N/A 1.1.1.1 Static No No
Do you have idea?
Best regards

Hello.
When I remove trunk in APs my network guest not working. The step "Authenfication" not working. I have enable web authentification in my WLC.
When I enter swithport mode access I don't arrive to ping my endpoint it's normal?
Thank you.

then there might be a layer 2 issue in then network, because as shown in this link http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a0080665cdf.shtml?referring_site=bodynav#aps
the required configuration on the switch which the APs connect to is to assign the ports to the management VLANs (AP-Manager)
can you provide the configuration of the switch

and provide show vlan brief

Hello.
I must separate the network "AP-Manager/management" and my Prod Network ? I don't understand this documentation.
I insert my network diagramm. Do you see my problem?
Thank you for your help.
Best regards
Stéphane
