WLC 5508 Conflicted IP

[dagoma999]

Hi,

 I have a problem whit WLC 5508. On this device are configurated 4 Wlan and function normally, but some times the connection lost just for one moment. Not is a very problem, but i want know why?

I have see in my log some times this conflict:

*dtlArpTask: (time): %LOG-1-Q_IND: dtl_net.c:3987 Network device with mac addr a4:93:4c:fb:a1:ef using IP address of local interface 'management'. 10.161.54.4 - Received ARP Reply on interface 13 with vlan ID 115. IP conflict is detected

I have see on my device:

the mac addres of my inventory it is much same, only the last caracter is different

And the ip mentioned on Log is ip of WLC management:

you Have idea? how to resolve this question?

Many thanks for all reply

What is means is another device on your network is using the same IP address as the WLC.

Uhmm, i think have found, but is ever this device, on the interface management:

I can shift this interfaces on another ip? or this is a good configuration?

Hey. Did you found a resolution for this?

Did you configure on every WLC and interface a different IP Address?
