System logging mechanism
The Brocade Mobility RFS7000-GR Controller provides subsystem logging to a Syslog server. There
are two Syslog systems, local and remote. Local Syslog records system information locally, on the
switch. The remote Syslog sends messages to a remote host. All Syslog messages conform to the
RFC 3164 message format.
Troubleshooting SNMP issues
The following SNMP-releated issued could require troubleshooting as SNMP issues are
experienced with the Brocade Mobility RFS7000-GR Controller.

All else... Contact Brocade Support.
Possible Problem Suggestions to Correct
Memory leak 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.
Too many concurrent Telnet or
SSH sessions Keep the maximum number of Telnet or SSH sessions low (6 or less), even though
up to 8 sessions are allowed.
