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. Be sure you have an active DHCP server available on the VLAN/subnet with the connected AP. If the AP still fails to get a valid IP address, you can reboot it to resolve the issue.
Unable to connect to the server.
  • Be sure you have an active server and reachable by the connected. If a firewall or a router has Access Control Lists (ACLs) enabled between the AP and the server, allow traffic on UDP port 3851.
  • Use the IP-based server discovery method and be sure you correctly entered the DNS name, wifi-security-server, on the DNS server.
  • Be sure the DNS server has correctly configured the IP addresses, or provided by the DHCP server.
  • The AP might fail to authenticate with the server. In this case, an 'Authentication failed ' event logs to 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, contact This email address is being protected from spambots. You need JavaScript enabled to view it..

Connecting the Access Point to the Network

To connect the AP to the network, perform the following steps:
  1. Be sure to install the AP on a network with a DHCP-enabled serve
  2. Set up a DNS entry for wifi-security-server on all DNS servers. This entry should point to the server IP address. By default, the AP looks for the DNS entry, wifi-security-server. 
  3. Verify the AP LED status as ON.
  4. Log on to the server using SSH and run the get sensor list command.

    The command returns a list of all Arista devices recognized by the server. Single Sign-On users can go to the Monitor tab in CloudVision Cognitive Unified Edge and check if the access point became visible on the tab.

Note:If zero configuration fails, the AP must be configured manually.

 

Important: If the subnet does not have DHCP enabled, the AP cannot connect to that subnet with zero-configuration. If no DNS entry exists on the DNS servers, or if you do not have a DHCP server running on the subnet, you must manually configure the AP. For details on configuring an AP manually, refer to the Access Point Configuration guide at Arista Product Documentation.

Connecting the Access Point using PoE

If using a PoE injector, be sure to plug the data connection into a suitable switch port with proper network connectivity.

For PoE port details, see the Rear Panel section.

Powering On the Access Point

Power the access point (AP) on by plugging one end of the Ethernet cable into the PoE++ switch or injector and the other end into the Ethernet/PoE++ port on the AP. Be sure to turn on the PoE ++ source.

As an alternative to PoE++, you can insert a compatible power adaptor plug into an AC power outlet and the other end into the power input port on the AP.

Note: If not using PoE++, ensure that you use only an AC power adaptor supported by the AP.

Using the Access Point with Power Adapter

Use a compatible power adapter (Arista SKU: PWR-AP-W5) to power the AP.

Warning:

Install the C-460E AP with a UL-listed PoE power source suitable for operation at 40ºC and output that meets LPS requirements or PS2, with a 48V DC (0.5A minimum) rating. If you do not use PoE+, install the AP with an AC power adapter with a Listed Direct Plug-In Power Unit marked “Class 2”, Listed Power Adapter, or DC power source marked “L.P.S.” (or “Limited Power Source”) and rated from 12 V DC, 2.5A minimum.

The maximum altitude of operation for the power adapter is 5000m.

To power up the device with power adapter, perform the following steps:
  1. Plug the power cable into the DC power receptacle on the back of the AP.
  2. Plug the other end of the power cable into an 110V~240V 50/60 Hz AC power source.
  3. Wait until the AP becomes ready. Refer to the LED status table.

Installing the Access Point

This chapter contains the procedure to install the access point (AP).

Zero-Configuration of the Access Point

The AP supports zero-configuration under the following conditions:

  • The device must be in AP mode with background scanning on and without a configured SSID.
  • Set up a DNS entry for wifi-security-server on all the DNS servers. This entry should point to the IP address of the server. By default, the AP looks for the DNS entry wifi-security-server.
  • Place the AP on a subnet with DHCP-enabled.

     

Refer to these articles to understand how APs communicate with the server, and the network ports to open for enabling the communication:
Important: If placing the device on a network segment separated from the server by a firewall, you must first open port 3851 for User Datagram Protocol (UDP) and Transport Control Protocol (TCP) bidirectional traffic on the firewall. This port number is assigned to Arista Networks. Zero-configuration does not support setting up multiple devices to connect to multiple servers. In this case, you must manually configure the APs. See the Access Point Configuration Guide on the Arista website at Arista Product Documentation.

 

Assign a static IP to the AP or change the settings to DHCP. Make a note of the MAC address and the IP address of the AP in a safe place before installing it in a hard-to-reach location. Locate the MAC address of the AP on a label at the bottom of the product.

Use the following steps to install the devices:
  1. Ceiling Mounting the Access Point or Wall Mounting the Access Point
  2. Connecting the Access Point to the Network
  3. Powering On the Access Point

Ceiling Mounting the Access Point

Mounting the access point (AP) on the ceiling consists of the following steps:

  1. Attach the bracket to the T-grid: Use the mounting bracket to install the AP on the ceiling. Attach the bracket to the T-grid and rotate the bracket so that it snaps on the T-grid. The bracket becomes parallel to an arm of the T-grid. Be sure the bracket properly snaps to the T-grid, as shown below.

     

  2. Mounting the AP on the bracket: Place the first mounting post on the rear-side of the AP on to the lower notch of the bracket. Rotate the AP so the center mounting post fits in to the center notch on the bracket. Be sure all the mounting posts on the rear-side of the AP snap into the respective notches on the bracket. The mounting posts now properly fit in the respective notches of the bracket and the AP mounts properly.

     

    Mounting Instructions using the Silhouette/Interlude Bracket Mount: The standard package does not include the Silhouette/Interlude mounting bracket and must be procured separately. The mounting instructions for the Silhouette/Interlude Bracket Mount contain steps similar to the Standard Package Content mounting instructions.
    Note: As a best practice, label the APs using MAC addresses or your own convention. For example, use AP serial numbers so that you can easily identify the APs.

Wall Mounting the Access Point

Note: The wall mounting accessory SKU (MNT-AP-FLAT-14CM) can be ordered and purchased separately.

 

For instructions on wall mounting the access point, refer to Wall Mount the Access Point article.

Connecting External Antennas to Access Point

Connect the external antennas to antenna ports available on the left and right of the AP. Use RP-SMA type connectors for the antennas. All the ports support multi-band connectivity - 2.4, 5, and 6 GHz.
