STATUS current
DESCRIPTION
"Maximum bandwidth allowed for this interface as a
whole, typically used to shape the outbound
transmission rate. The value is specified in terms
of percentage of overall link speed for the port in
1% increments. A value of 0 means there is no
maximum bandwidth limit in effect and that the
interface is allowed to transmit up to its maximum
line rate (i.e., work conserving method).
The default value is 0.
When set to a non-zero value, the interface is
restricted to using at most the bandwidth specified
in this object for the outbound transmission rate
(i.e., non-work-conserving method). This bandwidth
value is independent of any per-queue maximum
bandwidth value(s) in effect for the interface, as
specified in the agentCosQueueMaxBandwidth ohject,
and should be considered as a second-level
transmission rate control mechanism that regulates
the output of the entire interface regardless of
which queues originate the outbound traffic.
Valid value ranges depend on the value returned by
object agentCosQueueIntfShapingRateUnits. If that
object returns percent(1), agentCosQueueIntfShapingRate
accepts values 0..100. If that object returns kbps(2),
agentCosQueueIntfShapingRate accepts values
0,64..4294967295."

"The management technique used for all queues on this

active queue management scheme is employed whereby
packet drop precedence is considered during times of
queue congestion using WRED parameters. The
necessary queue management parameters are specified
in the agentCosQueueMgmtTable for the corresponding
agentCosQueueIntfIndex value. The default for this
object is taildrop(1).
Implementations that support this object but do not
support weighted RED must return taildrop(1) for this

agentCosQueueWredDecayExponent OBJECT-TYPE
SYNTAX Unsigned32 (0..15)
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The decay exponent value used with the weighted
random early discard (WRED) algorithm to determine
how quickly the average queue length calculation
reacts to the current length of the queue. A higher
value produces a slower response, meaning previously
sampled queue length values are factored into the
calculation for a longer period of time. The default
value is 9.
Use caution when changing this value from its
default. If set too low, short traffic bursts can
cause WRED to drop too many packets. If set too
high, WRED might not detect queue congestion in a
timely manner and becomes ineffective. The default
value should be sufficient for most users.
This object value is only used when the
agentCosQueueMgmtType is set to wred(2) and is
otherwise ignored."

This object always reads as disable(2). This object may

DESCRIPTION
"A scaling factor used for the WRED calculation to
determine the packet drop probability for the current
drop precedence level. The value is specified as a
number S from 1-15 and is used in the formula: 1/(2**
S), meaning one packet is dropped out of every (2**
S). Packet dropping begins when
agentCosQueueMgmtWredMinThreshold is reached and
proceeds linearly up to the (2**S) value specified by
this object until the
agentCosQueueMgmtWredMaxThreshold is reached, beyond
which all packets are dropped. Smaller values of S
produce a steeper slope, hence a higher incidence of
randomly dropped packets.
The default value is 10, which corresponds to a drop
rate of 1 out of every (2**10)=1024 packets.
This object is only used when agentCosQueueMgmtType
is set to wred(2)."

STATUS current
DESCRIPTION
"Tail drop queue threshold above which all packets
are dropped for the current drop precedence level.
The value specifies the threshold based on a percentage
of the overall device queue size. Since device
implementations vary, the actual value deployed may
be rounded up or down accordingly.
The default value, for all queues, is 100% for drop
precedence 1 and non-TCP traffic, 90% and 80% for
drop precedences 2 and 3.
This object is only used when agentCosQueueMgmtType
is set to taildrop(1)."

DESCRIPTION
"Weighted RED minimum queue threshold, below which no
packets are dropped for the current drop precedence
level. The value specifies the threshold based on a
percentage of the overall device queue size. Since device
implementations vary, the actual value deployed may
be rounded up or down accordingly.
The default value, for all queues, is 100% for non-TCP
traffic, 40%, 30% and 20% for TCP drop precedences 1, 2
and 3.
This object is only used when agentCosQueueMgmtType
is set to wred(2). Any value set for this object must
be equal to or less than the value of
agentCosQueueMgmtPercentWredMaxThreshold."
