WORD <1-1536> <1-3600> {absolute|delta} [falling-threshold <-2147483647-2147483647> event <1-65535> ] [owner WORD<1-127> ] [rising-threshold <–2147483647-2147483647> event <1-65535>]
|
Creates an alarm interface.
<1-65535>— Specifies the interface index number from 1 to 65535. Each entry
defines a diagnostics sample at a particular interval for an object
on the device. The default is 1.
WORD <1-1536>— Specifies the variable name or OID. The entry is case sensitive
and can have a string length of 1 to 1536.
{absolute | delta} — Specifies the sample type.
rising-threshold <-2147483648-2147483647> [<event:1-65535>] — Specifies the rising threshold from -2147483648 to 2147483647,
which is a threshold for the sampled statistic. After the current
sampled value is greater than or equal to this threshold, and the
value at the last sampling interval was less than this threshold,
the system generates a single event. The system also generates a single
event if the first sample after this entry that becomes valid is greater
than or equal to the rising alarm, or the rising or falling alarm.
After the system generates a rising event, the system does not generate
another such event until the sampled value falls below this threshold
and reaches the alarm falling threshold. You cannot modify this object
if the associated alarm status is equal to valid.
<1-65535>— Specifies the rising event index, which the system uses after the
system crosses a rising threshold. The event entry identified by a
particular value of this index is the same as identified by the same
value of the event index object. If no corresponding entry exists
in the event table, no association exists. In particular, if this
value is zero, the system does not generate an associated event, as
zero is not a valid event index. You cannot modify this object if
the associated alarm status is equal to valid.
falling-threshold <-2147483648-2147483647>
[<event:1-65535>] — Specifies the falling threshold
from -2147483648 to 2147483647, which specifies a threshold for the
sampled statistic. If the current sampled value is less than or equal
to this threshold, and the value at the last sampling interval was
greater than this threshold, the system generates a single event.
The system also generates a single event if the first sample after
this entry that becomes valid is less than or equal to this threshold
and the associated alarm startup alarm is equal to falling alarm or
rising or falling alarm. After the system generates a falling event,
the system does not generate another such event until the sampled
value rises above this threshold, and reaches the alarm rising threshold.
You cannot modify this object if the associated alarm status is equal
to valid.
<1-65535> – Specifies the index of the event entry that
the system uses after a falling threshold is crossed. The event entry
identified by a particular value of this index is the same as identified
by the same value of the event index object. If no corresponding entry
in the event table exists, no association exists. In particular, if
this value is zero, the system does not generate an event, as zero
is not a valid event index. You cannot modify this object if the associated
alarm status is equal to valid. The default is 60535.
owner WORD<1-127> — Specifies the name of the owner, with a string length 1 to 127.
Use the default operator to reset
the RMON alarms to their default configuration: default rmon
alarm <65535>
Note:
When configuring from CLI, the default owner is cli; when configuring with SNMP, the
default owner is snmp. The default command only sets the
owner to default. No other parameters can be changed
after you create the alarm.
Use the no operator to disable RMON alarms: no rmon alarm [<1-65535>]

event <1-65535> [community WORD<1-127>] [description WORD<0-127>] [log]
[owner WORD<1-127> ] [trap]
|
Create an event.
<1-65535>— Specifies the event index number. Each entry defines one event
that the system generates after the appropriate conditions occur.
The default is 1.
log — Specifies
if this event stores a log when the event is triggered by the alarm.
trap — Specifies
if this event sends a trap when the event is triggered by the alarm.
The trap will be sent to all the snmp-server hosts configured in the
snmp table.
description WORD<0-127>— Specifies the event description, with a string length of 0 to 127.
owner WORD<1-127> — Specifies the name of the owner, with a string length of 1 to
127.
community WORD<1-127> — Specifies the SNMP community where you can send SNMP traps, with
a string length 1 to 127.
You can set the community, but the
trap is not filtered out. The trap is sent to all configured snmp-server
hosts, regardless of the value of this field.
Use the no operator to delete a RMON event: no rmon event [<1-65535>]

<1–65535>][interval
<1–3600>][owner
WORD<1–127>]
|
Configures RMON history.
-
<1-65535> — Specifies the
history index number that uniquely identifies an entry
in the history control table. Each entry defines a set
of samples at a particular interval for an interface on
the default. The default value is 1.
-
{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}
— Specifies the single port interface. Identifies the
source for which the system collects and places
historical data in a media-specific table on behalf of
this history control entry. The source is an interface
on this device. The statistics in this group reflect all
packets on the local network segment that attaches to
the identified interface.
-
buckets
<1–65535>— Specifies the requested
number of discrete time intervals where the system saves
data in the part of the media-specific table associated
with this history control entry. The default value is
50.
-
interval
<1–3600>— Specifies the time
interval in seconds over which the system samples the
data for each bucket in the part of the media-specific
table associated with this history control entry.
Because the counters in a bucket can overflow at their
maximum value with no indication, you must take into
account the possibility of overflow in all the
associated counters. Consider the minimum time in which
a counter can overflow on a particular media type, and
then set the history control interval to a value less
than this interval, which is typically most important
for the octets counter in a media-specific table. The
default value is 1800.
-
owner
WORD<1–127>— Specifies the name of
the owner.

stats
<1-65535>
{sub-port]][,...][slot/all][all]}owner WORD<1–127>
|
Configures RMON statistics.
-
<1-65535>— Specifies the
control Ether statistics entry index number.
-
{slot/port
[/sub-port][-slot/port[/sub-port][,...]}—
Specifies the single port interface.
-
owner
WORD<1–127> — Specifies the name of
the owner.

util-method
[half|full]
|
Configures whether port utilization is calculated in half or full
duplex to calculate port usage.
After you select half for half duplex, RMON uses InOctets and the
speed of the port to calculate port usage (this is the standard RMON
RFC 1271 convention). After you select full for full duplex, RMON
uses InOctets and OutOctets, and 2X the speed of the port to calculate
port usage. If you select full, but the port operates in half-duplex
mode, the calculation defaults to the RFC1271 convention. The default
is half.
