C.1.4 Miscellaneous Issues
This section describes various miscellaneous issues related to the Motorola RF Series Switch which don't
fall into any of the previous categories. Possible issues include:
• Excessive Fragmented Data or Excessive Broadcast
• Excessive Memory Leak
C.1.4.1 Excessive Fragmented Data or Excessive Broadcast
Excessive fragmented data or excessive broadcast.
Suggestions to Correct
Verify that the preamble type matches between switch and MUs. Try a different
setting.
Verify in Syslog that there is not a high rate of decryption error messages. This
could indicate that a device key is incorrect.
Verify the device is not in the "do not adopt ACL".
Verify Keyguard is set on the client if the Security/WLAN Policy calls for
Keygaurd.
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.
