# Monitoring a QLLC Port Interface

To monitor a QLLC port interface, from the CiscoView Configure Window, select Interface from the CATEGORY popup menu. The following information is displayed:

Utilization

In Error Pkt%

Out Errors

In BPS Average (5 min)

Out BPS Average (5 min)

Out Collisions

In Queue Drops (locIfInputQueueDrops)

Out Queue Drops (locIfOutputQueueDrops)

# Utilization

Determines the rate of utilization on the specified port. The utilization rate is determined by the following formula:

(ifInOctets + ifOutOctets) / ifSpeed * 800

# In Error Pkt%

Specifies the incoming error rate on the port. The error rate is determined by the following formula:

ifInErrors / (ifInUcastPkts + ifInNUcastPkts) * 100

# Out Errors

Specifies the outgoing traffic rate on the port. The error rate is determined by the following formula:

ifOutErrors / (ifOutUcastPkts + ifOutNUcastPkts) * 100

# In BPS Average (5 min)

Provides a 5-minute exponentially delayed average of CPU input bits-per-second.

# Out BPS Average (5 min)

Displays a 5-minute weighted average of output bits-per-second for the specific protocol.

# Out Collisions

Displays the number of output collisions detected on this interface.

# In Queue Drops (locIfInputQueueDrops)

Displays the number of packets dropped because the input queue was full.

# Out Queue Drops (locIfOutputQueueDrops)

Displays the number of packets dropped because the output queue was full.
