This option lets you define a set of rules, which, on deployment, are translated to a single ACL. Because each device supports a finite number of ACLs, you might want to define traffic classifier rules as a single ACL. Click Edit to create traffic classifier rules as a single ACL. See Single ACL Translation Editor Dialog Box; Single ACL Translation Conditions Editor Dialog Box for details.
When you define a Single ACL Translation condition, the Protocol, Source IP, and Destination IP conditions in the Rule Settings page are disabled. If you need to define these elements as part of a traffic classifier rule, define them in the Single ACL Translation condition.
This field is only displayed when Class Based QoS scheduling (Modular QoS CLI) is selected.
Note When you use QoS analysis to monitor policies with traffic classifiers defined as a single ACL, the traffic classifier report only shows matching traffic for the entire ACL. It does not show you the breakdown for elements within the ACL.

SRR Queue In Configurations Page
Use this page to configure SRR features on the ingress queue, so that you can control the rate at which packets are sent to the stack ring of the device on which the policy is deployed.
In this way, you can prioritize traffic by placing packets with particular class of service (CoS) into certain queues, and adjusting the queue thresholds so that packets with lower priorities are dropped
The queues share the bandwidth among them according to the configured weights. The bandwidth is guaranteed at this level but not limited to it.
For example, if a queue is empty and no longer requires a share of the link, the remaining queues can expand into the unused bandwidth and share it among them. With sharing, the ratio of the weights controls the frequency of dequeuing; the absolute values being meaningless.
You have the option to use buffer allocation together with the bandwidth allocation. This helps you to control the data that can be buffered and sent before packets are dropped.
The queues use WTD (weighted tail-drop) to manage the queue lengths and to provide drop precedences for different traffic classifications. You assign the two explicit WTD threshold percentages for threshold ID 1 and ID 2 to the ingress queues. Each threshold value is a percentage of the total number of allocated buffers for the queue.
You can use the priority queue feature for traffic that needs to be expedited (for example, voice traffic, which needs minimum delay and jitter). SRR services the priority queue for its configured weight, before sharing the remaining bandwidth with both the ingress queues.
Using this page, you can set the weighted threshold drop percentages, buffer values, and bandwidth percentages for queues, and set priority queue and weightage. You then map the queue to a particular CoS value, or map the queue and threshold sets to a particular CoS value
To open this page, in the QoS Properties page, click Edit corresponding to Ingress Queue SRR Configurations.

|
Click this checkbox to allocate bandwidth for the two ingress queues. SRR services the queues based on the bandwidth ratio.
|
Queue 1
|
Enter the percentage of buffers/bandwidth (as the case may be) allocated to Queue 1. Enter a value between 0 and 100.
Note In case of buffer values, the sum of the buffer values entered in the Queue 1 and Queue 2 fields should be equal to 100.
|
Queue 2
|
Enter the percentage of buffers/bandwidth (as the case may be) allocated to Queue 2. Enter a value between 0 and 100.
Note In case of buffer values, the sum of the buffer values entered in the Queue 1 and Queue 2 fields should be equal to 100.
|
Set Priority Queuing Weights
|
Click this checkbox to set a specified queue as the priority queue with a weight.
|
Queue Number
|
Enter the queue number (1 or 2) that should be given priority.
|
Weight
|
Enter the bandwidth percentage to guarantee bandwidth for the priority queue on the stack ring, if the ring is congested. The range is 0 to 40.
|
Queue ID
|
Enter a queue ID to which packets with the corresponding CoS (CoS1 to CoS7) should be queued. The range of queue ID is 1 to 2.
|
Threshold ID
|
Enter a threshold ID for the queue ID to which packets with the corresponding CoS (CoS1 to CoS7) should be queued. The range of threshold ID is 1 to 3. The drop-threshold percentage for Threshold ID 3 is predefined and is set to the queue-full state.
|
SRR Queue Out Configurations Page
Use this page to map class of service (CoS) values to an egress queue ID and a threshold ID, or only to an egress queue ID.
In this way, you can prioritize traffic by placing packets with particular CoS into certain queues and adjusting the queue thresholds so that packets with lower priorities are dropped.
To open this page, in the QoS Properties page, click Edit corresponding to Egress Queue SRR Configurations.
Table B-57 SRR Queue Out Configurations Page
Field
|
Description
|
Queue ID
|
Enter a queue ID to map it to any CoS value (CoS1 to CoS7). The range of queue ID is 1 to 4.
|
Threshold ID
|
Enter a queue threshold ID to map it to any CoS value (CoS1 to CoS7). The range of threshold ID is 1 to 3.
|
Egress Queue Configurations Page
Use this page to guarantee the availability of buffers, set drop thresholds, and configure the maximum memory allocation for an egress queue-set.
The buffer space is divided between the common pool and the reserved pool. Based on this configuration, the device detects whether the target queue has not consumed more buffers than its reserved amount (under-limit), whether it has consumed all of its maximum buffers (over limit), and whether the common pool is empty (no free buffers) or not empty (free buffers). If the queue is not over-limit, the device can allocate buffer space from the reserved pool or from the common pool (if it is not empty). If there are no free buffers in the common pool or if the queue is over-limit, the device drops the frame.
The queues use WTD (weighted tail-drop) to support distinct drop percentages for different traffic classes.
Using this page, you configure threshold limits, reserved threshold, and maximum threshold, on different egress queues of two available queue sets. You can also allocate buffers on the queue sets.
To open this page, in the QoS Properties page, click Edit corresponding to Egress Queue Configurations.
Table B-58 Egress Queue Configurations Page
Field
|
Description
|
Threshold 1
|
Enter the first WTD (weighted tail-drop) threshold percentage value, which corresponds to Threshold ID 1, to be assigned to the egress queue. Enter a value between 1 and 3200 (for Cat 3750 Metro only) or 1 and 400 (for all other devices which support SRR configuration).
You will be assigning packets with a particular CoS value to a corresponding egress queue ID and threshold ID 1, and these packets will be dropped if this threshold percentage value is exceeded.
|
Threshold 2
|
Enter the second WTD (weighted tail-drop) threshold percentage value, which corresponds to Threshold ID 2, to be assigned to the egress queue. Enter a value between 1 and 3200 (for Cat 3750 Metro only) or a value between 1 and 400 (for all other devices which support SRR configuration).
You will be assigning packets with a particular CoS value to a corresponding egress queue ID and threshold ID 2, and these packets will be dropped if this threshold percentage value is exceeded.
|
Reserved Threshold
|
Enter the percentage of allocated memory to be guaranteed (reserved) for the queue. Enter a value between 1 and 100.
|
Maximum Threshold
|
Enter a percentage for the maximum memory the queue can have before the packets are dropped. Enter a value between 1 and 400.
|
Allocate Buffer
|
Click this checkbox to allocate buffers to a queue set, after entering the buffer space allocation (percentage) for each queue, in the corresponding fields. Enter values within the following range in the corresponding fields:
• 0 to 99 - for Queue 1, Queue 3, and Queue 4
• 1 to 100 - for Queue 2
Note The sum of buffer values entered for queues 1 to 4 should be equal to 100.
Note Allocate buffers according to the importance of the traffic; for example, give a large percentage of the buffer to the queue with the highest-priority traffic.

|
Packet size (optional)
|
(CQ only) The typical packet size, in bytes, that traverses the interface. QPM uses this value to calculate the byte size of the custom queues, the queues being a multiple of this packet size.
|
Queue limits (optional)
|
(PQ only) The limit for the number of packets allowed in each priority queue. After the limit is reached, packets are dropped.
|
Configure the distributed Weighted Fair Queuing properties (optional)
|
(dWFQ only)
• Aggregate Limit—The limit for the total number of packets allowed in all queues.
• Individual Limit—The limit for the number of packets allowed in each individual queue.
|
Configure the Fair Queuing properties (optional)
|
(FQ only)
• Aggregate Limit—The limit for the total number of packets allowed in all queues.
• Individual Limit—The limit for the number of packets allowed in each individual queue.
|

|
(WFQ only, and only when the device constraints are defined for frame relay interfaces)
Enable FRTS—Select to enable FRTS. The following options are displayed:
• Discard Threshold—The number of messages allowed in a weighted fair queue. For high-bandwidth conversations, once this threshold is met, additional high-bandwidth messages are discarded.
The threshold can be from 1 to 4096.
• Dynamic Conversation—The number of dynamic queues to use for conversations that do not require special network services ("best-effort conversations").
The dynamic conversation can be 16, 32, 64, 128, 256, 512, 1024, 2048, or 4096.
• Reservable Conversation—The number of reservable queues used for RSVP reserved conversations.
The reservable conversation can be from 0 to 100, unless you configure a fragment size for FRTS voice configuration, in which case the value can be from 2 to 100.
• Max Buffer Size [MAX.]—The maximum buffer size for the weighted fair queues, in number of messages. The buffer size can be from 0 to 4096.
|
Configure the transmit 1P2Q2T queues: Configure Transmit Queue/Maximum Threshold Values
|
These properties configure the transmit queues used for outbound traffic based on the IP precedence setting in the packets.
Every interface that is controlled by a particular ASIC uses the same 1P2Q2T configuration. If you configure one interface in an ASIC group, all interfaces are configured.
If you place two interfaces within an ASIC group in different policies with different 1P2Q2T configurations, the configuration used is the last one QPM applies to the device.
See the configuration documentation for your device for more information about ASIC groups.
• Queue Length—The percentage of the port's bandwidth allocated to each queue. The minimum queue percentage is 1. The values for the queues must add up to 100%.
Although all characteristics of these queues have default values, you must configure all values to change any value.
• Weight—The relative weight for the queue. This weight is used to determine how much traffic is transmitted from the queue using the weighted round-robin (WRR) technique before servicing the next queue.
The weight is from 1 to 255. The higher the weight, the more traffic is transmitted from the queue before servicing the next queue.
For 1P2Q2T, Queue 3 does not have an associated weight because it is a strict priority queue that transmits traffic whenever it is detected.
|
Configure the transmit 1P2Q2T queues: Configure Transmit Queue/Maximum Threshold Values
|
Maximum Threshold:
• Threshold1—The percentage of the queue's bandwidth to use as the first threshold limit. In the mapping table, you assign traffic to this limit. Any assigned traffic that exceeds the limit is dropped.
Queue 3 does not have a threshold because it is a strict priority queue. Traffic is only dropped when this queue's buffer is 100% full.
Thresholds 1 and 2 are not exclusive; they do not have to add up to 100%.
• Threshold 2—The percentage of the queue's bandwidth to use as the second threshold limit. In the mapping table, you assign traffic to this limit. Any assigned traffic that exceeds the limit is dropped.
Queue 3 does not have a threshold because it is a strict priority queue. Traffic is only dropped when this queue's buffer is 100% full.
Threshold 2 is typically larger than threshold 1. The difference between threshold 2 and 1 is the amount of the queue's bandwidth that is exclusively reserved for threshold 2 traffic.
For example, if threshold 2 is 100% and threshold 1 is 40%, 60% of the queue's bandwidth can be used only by traffic assigned to threshold 2.

Configure the transmit 2Q2T queues
(Queue Length and Weight)
|
These properties configure the transmit queues used for outbound traffic based on the IP precedence setting in the packets.
Every interface that is controlled by a particular ASIC uses the same 2Q2T configuration. If you configure one interface in an ASIC group, all interfaces are configured.
If you place two interfaces within an ASIC group in different policies with different 2Q2T configurations, the configuration used is the last one QPM applies to the device.
See the configuration documentation for your device for more information about ASIC groups.
• Queue Length—The percentage of the port's bandwidth allocated to each queue. The minimum queue percentage is 1. The values for the queues must add up to 100%.
Although all characteristics of these queues have default values, you must configure all values to change any value.
• Weight—The relative weight for the queue. This weight is used to determine how much traffic is transmitted from the queue using the weighted round-robin (WRR) technique before servicing the next queue.
The weight is from 1 to 255. The higher the weight, the more traffic is transmitted from the queue before servicing the next queue.
For 1P2Q2T, Queue 3 does not have an associated weight because it is a strict priority queue that transmits traffic whenever it is detected.

Configuring queue 3 as priority queue
|
(4Q1T Shape queuing only) Select to define queue 3 as the priority queue.
If queue 3 is the priority queue, packets in queue 3 are transmitted before those in other queues provided that the queue is running below the queue's configured bandwidth.
If shaping is configured for queue 3, the shape rate is honored even if queue 3 is defined as a priority queue.
|
4Q1T Shape Queue Configuration
|
(4Q1T Shape queuing only) Configure each of the four queues.
• Bandwidth
Optionally, enter the minimum bandwidth for each queue, in kilobits per second, or as percentage. The device will service the queue at least at this rate. By default, each queue gets 25% of the interface's bandwidth.
If you leave Bandwidth blank for a queue, that queue shares any excess bandwidth with all other queues. If the combined bandwidths for all queues exceeds the maximum speed of the interface, all queues share the link's bandwidth.
• Shape
Optionally, enter the maximum bandwidth for each queue, in kilobits per second, or as percentage. If no excess bandwidth is available, the device limits the queue to this rate. By default, there are no shaping limits on the queues.
|
Configure the WRR queues
|
(WRR queuing only)
These values configure the weights of the WRR queues used for an interface or pair of interfaces on layer 3 switches.
The weight implies a bandwidth for the queue, although the queue is not given an explicit bandwidth. The higher the weight, the higher the implied bandwidth. You can calculate the implied bandwidth using this equation:
W/S x B = n where:
• W is the weight
• S is the sum of the weight on all active queues on the port
• B is the bandwidth for the port in Mbps
• n is the bandwidth for the queue in Mbps
For example, if the queue weight is 4, the sum of the queue weights is 15, and the bandwidth on the interface is 100 Mbps, then the bandwidth for the queue is 26 Mbps.

Frame Relay Traffic Shaping Properties
(Enable FRTS, Rate, and MinCIR settings)
|
• Enable FRTS—Select this to use the rate control features of Frame Relay traffic shaping (FRTS).
To configure FRTS on subinterfaces and DLCIs, you must also enable FRTS on the parent interfaces, without configuring any FRTS properties. See Configuring FRTS Policies, page 8-32 for more information.
• Rate—The committed information rate (CIR), which is typically the rate you are committed to provide on the circuit. Enter the average kilobits per second (KBit/sec) rate for the virtual circuit or interface. The default is 56.
Instead of specifying the rate in kbps, you can specify a percentage of the interface's rate. For example, to indicate the rate should be the same as the rate of the interface, enter 100 and select Ratio. This makes it possible to use a single policy for interfaces that have different rates.
You can also define a rate below or above the interface speed. To define a rate above the interface speed, enter a value more than 100.
• MinCIR—Optionally, the minimum CIR (minCIR) value to be used when congestion occurs. The default minimum rate is half of the CIR. The actual bandwidth allocation during times of congestion is a percentage of the minimum rate, rather than a percentage of the CIR.
If you specify the rate as a percentage of the interface, you must also specify MinCIR as a percentage (if you specify a value).
|
Frame Relay Traffic Shaping Properties
(Burst and Exceed Burst settings)
|
• Burst Size—Optionally, the sustained number of kilobits that can be transmitted per interval over the virtual circuit. The burst size can be from 0.3 to 16000.
The interval is determined by dividing the burst size by the rate. For example, if the rate is 128 kilobits, and the burst size is 16 kilobits, the interval is 0.125 seconds, or 125 milliseconds (ms).
Instead of specifying the burst size in kilobits, you can specify the size of the interval in milliseconds (ms). This is helpful if you want the policy to apply to interfaces of differing rates. For example, if you want the interval size to be 10 ms (the recommended interval for interfaces that support IP telephony), enter 10 and select ms. QPM calculates the burst size in kbits by multiplying the interval size by the rate.
• Exceed Burst Size—Optionally, the maximum number of kilobits in excess of the burst size that can be transmitted during the first interval when congestion occurs. The exceed burst size can be from 0 to 16000.
If you specify the burst size in milliseconds, the exceed burst size is also in milliseconds. The recommended value for IP telephony interfaces is 0. QPM calculates the exceed burst size in kbits by multiplying the interval size by the rate.
• Configure Traffic Rate—Select this option to configure all the traffic-shaping characteristics of a virtual circuit (VC) in a single command.
Enter the Average kilobits per second (KBit/sec); equivalent to specifying the contracted committed information rate (CIR).
Optionally enter Peak kilobits per second (KBit/sec); equivalent to CIR + Be/Tc = CIR (1 + Be/Bc) = CIR + EIR. If the peak value is not configured, the peak rate will default to the configured average value.
|
Modular Shaping Properties
|
• Enable Modular Shaping—Select to enable shaping on all traffic flows on the interface.
• Shaping type—Choose the type of shaping action:
– Average—The interface sends no more than the committed burst (Bc) for each interval.
– Peak—The interface sends the committed burst (Bc) plus the excess burst (Be) in each interval.
• Rate (kbit/sec or ratio%)—The target average rate for the traffic, in kilobits per second, or as a percentage of the interface's actual rate.
• Burst size (optional) (kbits or ms)—The sustained number of kilobits that can be transmitted per interval over the interface. The interval is determined by dividing the burst size by the rate.
If you specify the burst size in milliseconds (ms), you are specifying the size of the interval. QPM calculates the burst size in kbits by multiplying the interval size by the rate.
• Exceed Burst size (optional) (kbits or ms)—The maximum number of kilobits in excess of the burst size that can be transmitted during the first interval when congestion occurs.
If you specify the burst size in ms, the exceed burst size is also in ms. QPM calculates the exceed burst size in kbits by multiplying the interval size by the rate.
|
Adaptive Shaping Properties
|
• Adaptive Shaping—Select this check box to have the interface reduce the traffic rate when it is notified that congestion is occurring at other interfaces along the path.
• Rate—Specify the traffic rate to be used when the interface is notified about congestion.
• Mark traffic with FECN—Select this check box to use the forward explicit congestion notification (FECN) to adjust the traffic descriptors, to approximate the rate to the available bandwidth along the path.

Description

Configure IP RTP Priority properties
|
IP RTP Priority is mainly useful on interfaces whose speed is less than 1.544 Mbps. Voice typically uses 24 Kbps. However, IP RTP Priority ignores voice compression, so a 12 Kbps stream is treated like a 24 Kbps stream. Because of overhead, ensure that the bandwidth percentage you select accommodates at least 25 Kbps per call.
You can use the max-reserved-bandwidth IOS software command to change the maximum allocatable bandwidth.
• Port Range—The starting and ending RTP port numbers. RTP traffic for these ports is placed in the strict-priority queue. Other traffic is handled by the interface's standard queuing mechanism.
The start port can be 2000 or higher, and the end port can be 65536 or lower. The maximum range is 16383. There is no default port range, but the voice ports range is from 16384 to 32767.
• Bandwidth—The percentage of the interface's bandwidth for the strict-priority queue. All packets in the queue are transmitted before any other queues are handled.
To determine the bandwidth required, estimate the number of concurrent calls that must be supported on the interface, and multiply by 25 Kbps. Then divide by the interface's bandwidth to get the bandwidth percentage.
Do not set the bandwidth too low. Any traffic for the queue that exceeds the bandwidth is dropped. Although voice traffic typically uses 24 kbps, there is occasional overhead requiring 25 kbps service.
If you select a bandwidth percentage that equates to 24 kbps, the interface is likely to drop voice packets occasionally, which will give you poor voice quality. Any unused bandwidth is available to the other queues on the interface.
The bandwidth can be between 0 and 75. There is no default. On interfaces configured with class-based QoS, this bandwidth is added to the combined queue bandwidths, and the total must be 75% or less.
|
IP RTP Header Compression Properties
|
• Enable IP RTP Header Compression—Select this to compress the IP/UDP/RTP header in an RTP data packet from 40 bytes to approximately two to five. This is typically used to help reduce delay for voice traffic.
• Passive—Select this to compress outgoing RTP packets only if incoming RTP packets on the same interface are compressed. Leaving this check box clear when Enable IP RTP Header Compression is selected will compress all RTP headers.
|
Link Fragmentation and Interleaving properties
|
• Enable LFI—Select this check box to reduce delay on slower-speed links for delay-sensitive traffic. Even if you select this field, QPM can only enable LFI on an interface if you have already configured the interface for multilink PPP (MLP), using the device's configuration commands.
• Maximum delay—Enter the maximum fragmentation delay in milliseconds.
|
Voice configuration properties (FRF)
|
• Enable voice configuration—Select this check box to configure the bandwidth and fragmentation for Voice over Frame Relay. These settings help you ensure that real-time, delay-sensitive voice traffic can be carried over Frame Relay links.
• Bandwidth—The percentage of the bandwidth configured for minCIR on the interface to reserve for voice traffic.
• Fragment (optional)—The frame size, in bytes, used when fragmenting data frames, not including Frame Relay headers and fragmentation headers.
Long data frames are fragmented and interleaved with real-time voice frames, so that data and voice can share the link while maintaining the required voice quality. Voice over Frame Relay frames are never fragmented.
The fragment size is in bytes, and can be from 16 to 1600. The default is 53 bytes.
Fragment is only available when you select WFQ or Class Based QoS for scheduling.
|
Configure Signaling Properties
|
• Enable RSVP—Select this to allow applications to make RSVP reservations on the interface. Some applications, such as VoIP, video, or audio broadcasts, use RSVP reservations to ensure that sufficient bandwidth is available at network devices along a traffic flow. This ensures that real-time traffic can flow through the network reliably, without delay and packet loss that can make the traffic flow useless.
When defined on interfaces configured with class-based QoS, RSVP and class-based QoS work independently, as if the other technique were not configured on the interface.
When configured on WFQ interfaces, RSVP provides guaranteed rate service, which is good for delay-sensitive applications like voice over IP.
When configured on WRED interfaces, RSVP provides controlled load service, which is good for adaptive real-time applications like the playback of a recorded conference call.
• UDP Encapsulation—Select this to have the interface produce a UDP-encapsulated multicast packet whenever it receives an IP-encapsulated multicast packet. If you do not select this field, the interface only uses UDP-encapsulated packets if it receives a UDP-encapsulated RSVP message (some hosts depend on the router to initiate UDP-encapsulation). The interface uses the 224.0.0.14 multicast address and UDP port 1699.
– Individual Limit—The percentage of the interface's bandwidth that one traffic flow can reserve. The single flow limit can be from 1 to the aggregate limit. The default is 75.
– Aggregate Limit—The percentage of the interface's bandwidth that all traffic flows combined can reserve. The aggregate limit can be from 1 to 75. The default is 75.
Note You must understand the bandwidth requirements of the RSVP-enabled applications on your network to make reasonable bandwidth settings.
|
Set QoS style
|
• Enable QoS style—Select this to choose the type of QoS configuration, for ports or for VLANs.
• VLAN-based—Select this when you want to configure VLAN-based policies on the ports.
When you choose this option, do not define policies in this policy group. You must create an additional policy group for the VLAN, containing the policies for the VLAN. See Configuring VLAN Policies, page 8-33 for more information.
• Port-based—Select this when you want to configure port-based policies.
|
Configure the Trust state properties
|
Enable Trust state—Select this to enable the trust state for the Catalyst switch port. The trust state affects how frames are marked when they enter the port.
• Untrusted—Change the frame's class of service (CoS) and type of service (ToS) values to the ones defined for the port.
This is the switch's default trust state.
• Trust CoS—Trust the CoS value on the packet and use it to change the packet's ToS value.
• Trust DSCP—Trust the packet's DSCP values without change.
• Trust IP Precedence—Trust the IP precedence value in the ToS byte.
|
Configure the Trust-ext properties
|
• Enable Trust-ext—(Catalyst 6000) Select to enable the trust extension settings for the Catalyst switch ports. These settings effectively extend the trust boundary of the switch to the IP phone and determine how packets at the trust extension boundary are marked.
– Untrusted—Negate the existing CoS settings. This is useful for a VoIP network where you have a PC-IP phone-Catalyst 6000 setup. To ensure that data from the PC gets no priority, you can set the trust extension to untrusted and then change CoS value of VoIP traffic to 5 and data traffic to 0. This ensures highest priority for voice traffic.
– Trust CoS—Trust the packet's existing CoS value.
• Enable Trust-Ext Marking—(Catalyst 4000) Select to have the IP phone port override the CoS priority received from the PC or other attached device and forward the received data with the CoS priority selected in the Mark CoS field.
|
Set TX Ring
|
Enable Tx Ring—Select to configure the size of the transmit rings (Tx-ring), which are buffer control structures for transmitting packets. The primary reason to adjust the transmit ring is to reduce latency caused by queuing.
• Buffer Size—Enter the buffer size of the transmit ring. This value should be small enough to avoid introducing latency due to queuing, but large enough to avoid drops, and a resulting impact to TCP-based flows.
|
Enable CoS Override
|
Click this checkbox to assign the default CoS to all incoming packets on the port. This overrides the CoS values of the incoming packets.
|
Enable QoS PreClassification
|
Click this checkbox to classify the packets before they are encapsulated by tunnel or encryption headers. This avoids the identical treatment of diverse packets in case the physical interface is congested.
|
Change Maximum Reserved Bandwidth
|
Click this checkbox to enable the override of the `75 percent rule' with a value you mention in the Bandwidth Percentage field. This feature helps if your particular traffic conditions and service policies can support to reserve more than 75 percent of the available bandwidth.
|
Bandwidth Percentage
|
Enter a value between 75 and 100 to specify the new percentage of total bandwidth to be used for fancy queing, overriding the `75 percent rule'.
|
Set inline power
|
Enable Inline Power—Select this to implement inline power on power-enabled Ethernet line cards.

Description
|
Value
|
Select the value for which you want to define threshold values—an IP precedence value, DSCP value, or RSVP.
Precedence or DSCP values that do not have settings are handled using default values.
|
Min. Threshold
|
The minimum number of packets held in the queue. When the average queue length falls between the minimum and maximum thresholds, packets are dropped based on the probability denominator. If the average queue size is lower than the minimum threshold, all packets are queued.
The minimum threshold in QPM can be from 1 to 4096. The default minimum threshold for precedence 0 is half the maximum threshold. The default minimums for the remaining values fall at even intervals between this value and the max threshold.
The average queue size is based on the current size of the queue, the last calculated average queue size, and the WRED weighting factor for the interface. See the IOS software documentation for the exact formula.
|
Max. Threshold
|
The maximum threshold for the queue. When the average queue length exceeds the maximum threshold, all new packets for the queue are dropped until the queue drops below the max threshold.
The maximum threshold must be larger than the minimum threshold up to 4096. The default is based on the output buffer capacity of the device and the speed of the interface.
|
Probability Denominator
|
The denominator for the number of packets that are dropped if the queue length reaches the minimum threshold. The higher the denominator, the fewer packets are dropped from the queue.
The probability denominator can be from 1 to 65536. The default is 10, that is, one packet in every 10 is dropped from a queue once the minimum threshold is reached.
The higher you set the probability denominator, the higher the chance that the maximum threshold will be reached.
