Important Considerations
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
system prompts you to choose the setting and then applies it to all of
the ports.
You can determine when a monitored port is in error and has been
disabled by these port statistics:
The
status
display reports
The
portState
ethernet detail displays reports
The
linkStatus
ethernet detail displays reports
When the monitoring feature reenables the port, port statistics
resume normal values.
The Ethernet monitoring feature in enabled by default, and performs
these functions:
1 Monitors 10/100Mbps Ethernet ports for excessive collisions,
multiple collisions, late collisions, runts, and FCS errors
2 Compares these error counters against user-defined thresholds
3 Disables a port that reaches an error threshold
4 Reports the reason that a port is disabled to the Administration
Console, MIB databases, and SNMP traps
5 Reenables the port after an initial backoff time interval
6 Continues monitoring
