5 Access Point Troubleshooting
The table below lists some of the troubleshooting guidelines for the access point (AP).
Problem Solution
The AP did not receive a valid IP address via the
DHCP. Ensure that the DHCP server is on and
available on the VLAN/subnet to which the AP
is connected. If the AP still fails to get a valid IP
address, you can reboot it to see if the problem is
resolved.
Unable to connect to the server.
• Ensure that the server is running and is
reachable from the network to which the AP is
connected. If a firewall or a router has Access
Control Lists (ACLs) enabled between the AP
and the server, ensure that traffic on UDP port
3851 is allowed.
• Use the IP-based server discovery method
and ensure that you have correctly entered
the DNS name, wifi-security-server , on the
DNS server.
• Ensure that the DNS server IP addresses are
either correctly configured, or are provided by
the DHCP server.
• The AP might fail to authenticate with the
server. In this case, an 'Authentication failed
' event is raised on the server. Refer to the
event for recommended action.
The AP has encountered a problem.
• If you are using Arista Cloud Services, then
open the TCP port 443 (SSL). If you have an
on-premises installation, then open UDP port
3851 and port 80.
• If you are using a Proxy, Web Accelerator,
or URL Content Filter between the AP and
the Internet, ensure that the settings allow
communication between the AP and Arista
Cloud Services.
• If your configuration requires you to specify
an exact IP address or IP range for Arista
Cloud Services, please contact support-
wifi@arista.com.
