Advanced Performance Monitoring overview
17
• ISL monitors measure the traffic transmitted through an InterSwitch Link (ISL) to different
destination domains.
• Top Talkers monitors measure the flows that are major consumers of bandwidth on a switch or
port.
The type of monitors supported depends on the switch model, as shown in Table 81 .
NOTE
Advanced Performance Monitoring is not supported on VE_Ports and EX_Ports. If you issue
commands for any Advanced Performance Monitors on VE_Ports or EX_Ports you will receive error
messages.
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 82 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 and end-to-end 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.
• ISL monitors are not supported on any of the platforms listed in Table 82 .
If you move a port 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, you
must manually install it on the port after the move.
