Important Considerations
■
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
module prompts you to choose the setting and then applies it to all of
the ports.
■
The Ethernet monitoring feature in enabled by default, and performs
these functions:
■
Monitors 10/100Mbps Ethernet ports for excessive collisions,
multiple collisions, late collisions, runts, and FCS errors
■
Compares these error counters against user-defined thresholds
■
Disables a port that reaches an error threshold
■
Reports the reason that a port is disabled to the Administration
Console, MIB databases, and SNMP traps
■
Reenables the port after an initial backoff time interval
■
Continues monitoring
■
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.
