Limitations of Top Talker monitors
• Top Talker monitors cannot detect transient surges in traffic through a given flow.
• You cannot install a Top Talker monitor on a mirrored port.
• Top Talker can monitor only 10,000 flows at a time.
• Top Talker is not supported on VE_Ports, EX_Ports, and VEX_Ports.
Monitoring trunks
For trunked ISLs on Fabric OS 4.x or later switches, monitoring is set only on the master ISL, which
communicates with the associated slave ISLs. Note the following:
• For Fabric OS 3.x switches, monitoring can be set on slave ISLs.
• End-to-end monitors are not supported for ISLs.
• 4/8 SAN Switch, 4/16 SAN Switch models support 8 filter-based monitors for trunks.
• The SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B, 400 Multi-protocol Router, 4/256 SAN
Director and DC Director switches support 12 filter-based monitors for trunks.
Displaying monitor counters
Use the perfMonitorShow command to display the monitors on a specified port. For end-to-end
counters, you can display either the cumulative count of the traffic detected by the monitors or a snapshot
of the traffic at specified intervals.
NOTE: 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B,
400 Multi-protocol Router, 4/256 SAN Director, and DC Director output does not include CRC counts.
The command format is:
perfmonitorshow --class monitor_class [slotnumber/]portnumber [interval]
monitor_class The monitor class, which can be one of EE (end-to-end), FLT (filter-based), or
ISL (inter-switch link). The
--class monitor_class operand is required.
