Aruba Central offline devices after creating DHCP-Server

Hello,

 

today I have a question about offline IAP AccessPoints in Aruba Central. Yesterday I configured in the Central Webinterface a new local DHCP Server for the MGMT-Network.

 

After creating all APs are offline in Central but the function of Wireless Network is working well.

 

HTTPS://ARUBA-VC is not answering, SSH is OK

 

so first test was 

ping www.google.de
no host www.google.de found

IP-Address same story

Routing-Table

AP-09# sh ip route
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface

10.49.0.0       0.0.0.0         255.255.255.0   U         0 0          0 br0
10.49.3.0       0.0.0.0         255.255.255.0   U         0 0          0 br0
172.31.98.0     0.0.0.0         255.255.254.0   U         0 0          0 br0

 

I don´t know what is wrong in my configuration, at last creating dhcp-server

 

so for testing, I want to delete the dhcp-server but I can only connect via ssh.

 

my question is how can I delete the dhcp-server for my mgmt-network?

 

I don´t understand why I cannot ping internet clients. on my switches on the same subnet is ping www.google.de oder IP-Address OK

 

Greetings from Germany

documentation on https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c05320370 you can find

 

DHCP-Server

 

Local—In this mode, the Virtual Controller acts as both the DHCP Server and the default gateway. The
configured subnet and the corresponding DHCP scope are independent of subnets configured in other IAP
clusters. The Virtual Controller assigns an IP address from a local subnet and forwards traffic to both
corporate and non-corporate destinations. The network address is translated appropriately and the
packet is forwarded through the IPSec tunnel or through the uplink. This DHCP assignment mode is used
for the NAT forwarding mode.

I don´t understand how can i delete the dhcp-server on cli

you can delete DHCP Scope with

no ip dhcp "profile name"

my mistake was that the profile name was not correct

 

the profile name is given with

 

show running-config

.......

ip dhcp profile name
 server-type Local
 server-vlan xxx
 subnet xxx
 subnet-mask xxx
 default-router xxx
 dns-server xxx
