dhcpdwrap[1839]: <202513> <DBUG> |dhcpdwrap| |dhcp| Could not find interface and/or vlan for ip

Hi,

       I recently configured a new SSID for 802.1x with wpa2-AES and have intermittent connectivity issues across the premises. Enabled the network log and my logs are flooded with similar messages below.

 

Jan 30 16:16:24  dhcpdwrap[1839]: <202513> <DBUG> |dhcpdwrap| |dhcp| Could not find interface and/or vlan for ip=192.168.5.155, could be reply to mobility message.

 

May the cause for the message and will this be the root cause for the intermittent root cause issues.

Are you using the Aruba Controller to provide DHCP?

Re: dhcpdwrap[1839]: <202513> <DBUG> |dhcpdwrap| |dhcp| Could not find interface and/or

yes I am using the DHCP on the controller.

Please find the dhcp pool configured for the SSID ,

 

ip dhcp pool GCC_Secure
 default-router 192.168.1.254
 dns-server 24.97.221.139 199.29.211.1
 lease 0 3 0 0
 network 192.168.0.0 255.255.252.0

What is the output of show ip dhcp statistics?

It is not recommended to have more than 512 addresses on the internal dhcp server. More than that and an external dhcp server is required.

Hi Please find the output

 

show ip dhcp statistics  


Network Name           192.168.4/22
    Free leases        551
    Active leases      395
    Expired leases     0
    Abandoned leases   0
                          
Network Name           192.168.0/22
    Free leases        869
    Active leases      70
    Expired leases     0
    Abandoned leases   0
                          

 

May i know what the error or log message meant for? Is this will create intermittent connectivity issues, that is an user has to try three to four times before he gets connected . this issue is seen randomly.

The truth is that the internal DHCP server is not meant to serve anything more than a small guest network.  You should use an external DHCP server for better performance and to ensure you do not have any interruptions.  The DHCP daemon simply does not run at a high priority in the controller and that will not change any time soon.

 

Get that external DHCP server as soon as possible.
