Resolve Network Problems

If a network loop occurs, make sure that you did not connect a GBIC and the Ethernet port on
the wireless controller (or two GBICs on the wireless controller) to the same network switch.
Make only a single connection from a wireless controller to a network switch.

Resolve Problems With Access Points

If you encounter access point discovery or connection problems, the information in this
section might help you to resolve these problems.

Resolve Discovery Problems

If the wireless controller does not discover any or all access points, check the configuration of
the wireless controller and access points.
For all access points, check the following:
• Make sure that the wireless controller is connected to the LAN (see
Are Not Lit on page 361).
• Make sure that you enter the correct IP range if the access points function in different
VLANs, are behind an IP subnet, or are already installed and working in standalone mode
(see Access Point Discovery Guidelines
• Make sure that the access points run at least their initial firmware release or a newer
version. For firmware requirements, see
page 27.
For local access points that are installed across a Layer 3 network, check the following:
• Enable SNMP and SSH on all standalone access points. (This is the default setting for
access points.)
• Unblock UDP port number 7890 in the firewall.
• Assign each access point a unique IP address. (This requirement does not apply to
access points in the factory default state that are in the same Layer 2 network.) If two or
more access points are assigned the same IP address, only one of them is discovered at
a time. You must add the access point to the managed list, change its IP address, and
run discovery again to discover the next access point with that IP address.
• Enable DHCP option 43 (vendor-specific information) on an external DHCP server.
Specifying an internal DHCP server on the wireless controller automatically enables
DHCP option 43 with the IP address of the wireless controller.
