Aruba Instant AP | Troubleshooting Guide

Run the
show ap arm history
command in the CLI of the AP to view the channel change history of the
radios. Frequent channel changes by the AP radio may affect the ability of client devices to discover and
connect to the SSID. This is commonly observed in clients with a limited channel range.
Check the Authentication Message Exchange Between the AP and
Client
Check the authentication logs in the AP to identify any association issues between the client and the AP.
Run the
show ap debug mgmt-frames <MAC address>
command to view authentication messages
exchanged between the client and the AP. Use the client MAC address in the MAC address parameter to
filter management messages specific to the client. Any authentication errors in the client association process
will be displayed in the output.
Wireless Client Unable to Get an IP Address
The following procedure describes how to troubleshoot issues, if the client fails to get an IP address:
1.
Check the VLAN Settings of the Network
2.
Debug the DHCP Packets of the Client
Before troubleshooting, ensure that the client is connected to the AP.
Check the VLAN Settings of the Network
Incorrect VLAN settings can stop the client from getting an IP address. Perform the following checks
depending on the VLAN configuration of your network:
VLAN Assignment Type
Action
Virtual Controller Managed
Ensure that the custom DHCP scope defined is valid and supported in the
subnet.
Network Managed
Ensure that the VLAN defined is allowed in the wired port profile.
For trunked VLANs, ensure that the VLAN is allowed in the uplink switch.
Ensure that a DHCP server is available in the uplink switch to supply
IP addresses to clients.
Debug the DHCP Packets of the Client
Run the
debug pkt match mac <mac address> type dhcp
in the CLI to view the dhcp packets
exchanged between the client and the AP for more information. Use the MAC address of the client in the
match
parameter to filter packets specific to a client.
The following command syntax is used to view the dhcp packets specific to a client:
(Instant AP)#debug pkt match <MAC address> type dhcp
(Instant AP)#debug pkt dump
Wireless Client Unable to Pass Traffic
