Important Considerations
■You can use this command to configure the same setting on m ultiple
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 value shown in the ethernet monitoring summary
display reports partitioned.
■The portState value shown in the ethernet summary and
ethernet detail displays reports partitioned.
■The linkStatus value shown in the ethernet summary and
ethernet detail displays reports disabled.
When the monitoring feature reenables the port, port statistics
resume normal values.
■The Ethernet monitoring feature in enabled by default, and performs
these functions:
1Monitors 10/100Mbps Ethernet ports for e xcessive collisions,
multiple collisions, late collisions, runts, and FCS errors
2Compares these error counters against user-defined thresholds
3Disables a port that reach es an error threshold
4Reports the reason that a port is disabled to the Administration
Console, MIB databases, and SNMP traps
5Reenables the port after an initial backoff time interval
6Continues monitoring
