Suggestions to Correct
If Encryption is being used, verify that the encryption settings on the MU and the switch
match.
If WEP Encryption is being used with non-Symbol or Motorola MUs, ensure that the key
being entered is in HEX format and not a Passphrase.
If the switch is configured to use RADIUS authentication, check the RADIUS log file for
any failure information.
If you are using Authentication and/or Encryption on the switch, and the previous
troubleshooting steps have not fixed the problem, try temporarily disabling
Authentication and Encryption to see if that fixes the problem.
Suggestions to Correct
• Maintain voice and data traffic on separate WLANs.
• Use a QoS Classifier to provide dedicated bandwidth if data and voice traffic are
running on the same WLAN.
Verify that a long preamble is used with Spectralink phones.
Suggestions to Correct
Verify the Primary and Secondary switches are Standby enabled and have the correct
MAC address configured for the correct Primary/Secondary switch.
Mismatch configurations are not allowed. Verify that the Primary and Secondary
switches have the same software versions running.
Verify that the Primary and Secondary switch are configured properly and attempt to
ping each switch (using the ping command) from each switch.
