Suggestions to Correct
Using the CLI or Web UI's Diagnostics section to check the available virtual
memory. If any one process displays an excessive amount of memory usage, that
process could be one of the possible causes of the problem.
Keep the maximum number of Telnet or SSH sessions low (6 or less), even though
up to 8 sessions are allowed.
Contact Brocade Support.
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.
Do not allow VoIP traffic when operating on a flat network (no routers or
smart switches).
Move to a trunked Ethernet port.
Move to a different configuration.
