Advanced Performance Monitoring overview

Restrictions for installing monitors
• Advanced Performance Monitoring is not supported on VE_Ports and EX_Ports. If you issue
commands for any Advanced Performance Monitoring on VE_Ports or EX_Ports, you will receive
error messages.
• For the Brocade 8000, Advanced Performance Monitoring is supported only on the FC ports
and not on the CEE ports.
• All monitor types are allowed only on physical ports.
• Top Talker monitors and EE monitors on E_Ports should be installed only in the ingress
direction.
Virtual Fabrics considerations for Advanced Performance Monitoring
In a fabric with Virtual Fabrics enabled, the number of logical switches that can be configured with
monitors is restricted. Table 73 lists the platforms that support logical switches and, for each
platform, the maximum number of logical switches that can support performance monitors.
Each logical switch can have its own set of performance monitors. The installation of monitors is
restricted to the ports that are present in the respective logical switch.
• Top Talker monitors and EE monitors are supported on the default logical switch, the base
switch, and user-defined logical switches.
• Frame monitors are not supported on logical ISLs (LISLs) in user-defined logical switches.
If a port is moved from one logical switch to another, the behavior of monitors installed on that port
is as follows:
• Frame monitor: Any frame monitors on the port are deleted. To keep the frame monitor, the
monitor must be manually installed on the port after the move.
• Top Talker (fabric mode): If the fabric-mode Top Talkers feature is enabled on the logical switch,
a fabric mode Top Talker monitor is automatically installed on the port after it is moved to the
logical switch.
• Top Talker (port mode): Any port mode Top Talker monitors on the port are deleted. To keep the
port mode Top Talker monitor, the monitor must be manually installed on the port after the
move.
