Chapter 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,
