Configuring Port Group Monitor

• We recommend that you use the delta threshold type for all the counters except the tx-slowport-oper-delay
Note
counter which uses absolute threshold type.
• The rx-datarate and tx-datarate are calculated using the inoctets and outoctets on an interface.
• You must activate the err-pkt-from-port, err-pkt-from-xbar, and err-pkt-to-xbar counters using the
monitor counter name command, before specifying the counter parameters.
• Counters err-pkt-from-xbar, err-pkt-from-port, and err-pkt-to-xbar support delta threshold type only.
• Counter tx-slowport-oper-delay supports absolute threshold type only.
• Counter tx-slowport-oper-delay does not support portguard action.
• You must first enable ER_RDY flow-control mode using the system fc flow-control er_rdy command
and then enable congestion isolation using the feature congestion-isolation command before setting the
portguard action as congestion isolate (cong-isolate). For more information, see
Port-Monitor Portguard Action for Congestion Isolation, on page
• The cong-isolate port monitor portguard action is used only for configuring the credit-loss-reco,
tx-credit-not-available, tx-slowport-oper-delay, and txwait counters.
