Displaying Monitor Counters
14
End-to-end monitors are not supported for ISLs.
SilkWorm 3016, 3250, 3850, 3900, 12000, 24000, and 48000 models support eight filter-based
monitors for trunks.
The SilkWorm 200E, 4012, and 4100 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.
The command format is:
perfmonitorshow --class monitor_class [slotnumber/]portnumber [interval]
N
ote
SilkWorm 200E, 4012, and 4100 outputs do not include CRC counts.
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.
slotnumber Specifies the slot number for a SilkWorm 12000, 24000, or 48000 director. For all
other switches, this operand is not required. The slot number must be followed by a
slash ( / ) and the port number, so that each port is represented by both slot number
(1 through 4 or 7 through 10) and port number (0 through 15).
The SilkWorm director has a total of 10 slots. Slot numbers 5 and 6 are control
processor blades; slots 1 through 4 and 7 through 10 are port blades. For 16-port
blades, there are 16 ports, counted from the bottom, numbered 0 to 15. For 32-port
blades, there are 32 ports numbered 0 to 31.
portnumber Specifies a port number. Valid values for port number vary, depending on the switch
type. This operand is required.
interval Specifies an interval in seconds. The interval must be greater than or equal to five
seconds. For end-to-end monitoring, the Tx and Rx counts are measured in bytes.
This operand is optional.
