7.4.18 perfquery
perfquery usesPerfMgt GMPs to obtain the PortCounters (basic performance and error coun-
ters), PortExtendedCounters, PortXmitDataSL, PortR-cvDataSL, PortRcvErrorDetails,PortX-
mitDiscardDetails, PortExtended- SpeedsCounters, or PortSamplesControl from the PMA atthe
node/port specified. Optionally shows aggregated counters for all ports of node. In addition, you
may reset after read, or only reset counters.
• In PortCounters, PortCountersExtended, PortXmitDataSL, and PortR-cvDataSL,
components that represent Data (e.g. PortXmitData and PortR- cvData) indicate octets
divided by 4 rather than just octets.
• Inputting a port of 255 indicates an operation be performed on all ports.
