Usage Guidelines
Aggregate policing works independently on each Distributed Forwarding Card (DFC)-equipped switching module and independently on the Policy Feature Card 2 (PFC2), which supports any non-DFC-equipped switching modules. Aggregate policing does not combine flow statistics from different DFC-equipped switching modules. You can display aggregate-policing statistics for each DFC-equipped switching module, the PFC2, and any non-DFC-equipped switching modules that are supported by the PFC2.
Examples
This example shows how to display information about the aggregate policer for MLS QoS:
Router# show mls qos aggregate-policer
ag2 64000 64000 conform-action set-dscp-transmit 56 exceed-action drop
ag3 32000 32000 conform-action set-dscp-transmit 34 exceed-action drop
In the output, the following applies:
•
The AgId parameter displays the hardware-policer ID and is nonzero if assigned.
•
The policy maps using the policer, if any, are listed in the square brackets ([]).
•
If there are no policies using the policer, no AgId line is displayed.
•
If the policer is referred to in policy maps, but has not been defined, [undefined] is displayed.

12.2SX |
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware. |
Usage Guidelines
Use the show mls qos interface command without keywords to display parameters for all interfaces.
Use the show mls qos interface interface-id command to display the parameters for a specific interface.
On most Cisco switch platforms, the global command, "(no) mls qos", is used to toggle the MLS QoS state to be enabled or disabled. When MLS QoS is disabled globally, the CoS/IP Precidence/DSCP values for all traffic passing through the switch will not be modified. On the other hand, if MLS QoS is enabled, then by default all interfaces will be in an untrusted state, which means all incoming CoS/IP Prec/DSCP values will be remarked down to 0.
Cisco 2600 and Cisco 3600 Series Switches
Becuase the (no) mls qos global command is not supported for the Cisco_2600 or Csico_3600 series switches, this presents a unique situationregarding the default trust state for the interface.
By default, when there is no "mls qos" related commands configured under an interface on the Cisco_2600 or Cisco_3600 series switches, the CoS/IP Prec/DSCP value of all incoming traffic will not be remarked as it passes through the switch. This has the same result as when MLS QoS is disabled on other Cisco switches.
Examples
The following is sample output from the show mls qos interface fastethernet0/1 command:
Router# show mls qos interface fastethernet0/1
The following example shows that there is no mls QoS command configured on the interface. the CoS/IP Precidence/DSCP values of incoming traffic will not be remarked as it passes through the switch.
Router# show mls qos interface f1/1

In the policed DSCP and DSCP-CoS map displays, the new DSCP or CoS values are shown in the body of the table. The decade of the original DSCP value is shown in the left-side vertical column, and the units digit is in the top row. For example, the DSCP-CoS map indicates that if the original DSCP value is between 32 and 39, the CoS will be set to 4.
The CoS-DSCP and IP precedence-DSCP maps display the DSCP values to which each CoS or IP precedence value will be mapped. For example, the IP precedence-DSCP map indicates that if the original IP precedence value is 3, the DSCP will be set to 24.
This example shows how to verify the configuration of DSCP-mutation mapping:
Router# show mls qos maps | begin DSCP mutation
DSCP mutation map mutmap1: (dscp= d1d2)
d1 : d2 0 1 2 3 4 5 6 7 8 9
-------------------------------------

4 : 40 41 42 43 44 45 46 47 48 49
In the DSCP mutation map display, the marked-down DSCP values are shown in the body of the table. The first digit (d1) of the original DSCP value is in the left-side vertical column labeled d1, and the second digit (d2) is in the top row. For example, a DSCP value of 30 maps to a new DSCP value of 08.

12.2XJC |
This command was introduced. |
Usage Guidelines
Cisco IOS-based switches support the wire-rate ACL and QoS feature with use of the TCAM. Enabling ACLs and policies does not decrease the switching or routing performance of the switch as long as the ACLs are fully loaded in the TCAM.
To implement the various types of ACLs and QoS policies in hardware, the Cisco IOS-based switches use hardware lookup tables (TCAM) and various hardware registers in the Supervisor Engine. When a packet arrives, the switch performs a hardware table lookup (TCAM lookup) and decides to either permit or deny the packet.
Examples
The following sample output from the show platform hardware acl entry global-qos command displays one result for inbound Address Resolution Protocol entries:
Switch# show platform hardware acl entry global-qos in arp
0x0000000000000003 arp ip any any mac any

12.2(18)SXE |
This command was introduced for Cisco Catalyst 6500 series switches and Cisco 7600 series routers. |
12.2(33)SRA |
This command was integrated into Cisco IOS Release 12.2(33)SRA. |
Usage Guidelines
On Cisco Catalyst 6500 series switches and Cisco 7600 series routers, you cannot attach a quality of service (QoS) policy map with match input vlan to an interface if you have already attached a QoS policy map to a VLAN interface (a logical interface that has been created with the interface vlan command). If you attempt to use both types of service policies, you must remove both types of service policies before you can add the policy maps.
The show platform qos policy-map command shows whether the router is currently configured for interface vlan and match input vlan service policies. It also shows the number of policy maps for each type.
Examples
The following example shows a router that has service policies configured only on VLAN interfaces:
Router# show platform qos policy-map
service policy configured on int vlan: TRUE
# of int vlan service policy instances: 3
match input vlan service policy configured: FALSE
# of match input vlan service policy instances: 0
The following example shows a router that has service policies configured on VLAN interfaces and that has a service policy configured with match input vlan. In this configuration, you must remove all service policies from their interfaces, and then configure only one type or another.
Router# show platform qos policy-map
service policy configured on int vlan: TRUE
# of int vlan service policy instances: 1
match input vlan service policy configured: TRUE
# of match input vlan service policy instances: 1
Table 176 describes each field shown in the show platform qos policy-map command:
Table 176 show platform qos policy-map Field Descriptions
|
|
service policy configured on int vlan |
Indicates whether any QoS policy maps are configured on VLAN interfaces. |
# of int vlan service policy instances |
Number of QoS policy maps that are configured on VLAN interfaces. |
match input vlan service policy configured |
Indicates whether any QoS policy maps that use the match input vlan command are configured on interfaces. |
# of match input vlan service policy instances |

Usage Guidelines
Cisco 3660, 3845, 7200, 7400, 7500, and Cisco ASR 1000 Series Routers
The show policy-map interface command displays the packet statistics for classes on the specified interface or the specified PVC only if a service policy has been attached to the interface or the PVC.
The counters displayed after the show policy-map interface command is entered are updated only if congestion is present on the interface.
The show policy-map interface command displays policy information about Frame Relay PVCs only if Frame Relay Traffic Shaping (FRTS) is enabled on the interface.
The show policy-map interface command displays ECN marking information only if ECN is enabled on the interface.
To determine if shaping is active with HQF, check the queue depth field of the "(queue depth/total drops/no-buffer drops)" line in the show policy-map interface command output.
In HQF images for Cisco IOS Releases 12.4(20)T and later, the packets delayed and the bytes delayed counters were removed for traffic shaping classes.
Cisco 7600 Series Routers and Catalyst 6500 Series Switches
The pos, atm, and ge-wan interfaces are not supported on Cisco 7600 series routers or Catalyst 6500 series switches that are configured with a Supervisor Engine 720.
Cisco 7600 series routers and Catalyst 6500 series switches that are configured with a Supervisor Engine 2 display packet counters.
Cisco 7600 series routers and Catalyst 6500 series switches that are configured with a Supervisor Engine 720 display byte counters.
The output does not display policed-counter information; 0 is displayed in its place (for example, 0 packets, 0 bytes). To display dropped and forwarded policed-counter information, enter the show mls qos command.
On the Cisco 7600 series router, for OSM WAN interfaces only, if you configure policing within a policy map, the hardware counters are displayed and the class-default counters are not displayed. If you do not configure policing within a policy map, the class-default counters are displayed.
On the Catalyst 6500 series switch, the show policy-map interface command displays the strict level in the priority feature and the counts per level.
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 1 to 13 and valid values for the port number are from 1 to 48.
HQF
When you configure HQF, the show policy-map interface command displays additional fields that include the differentiated services code point (DSCP) value, WRED statistics in bytes, transmitted packets by WRED, and a counter that displays packets output/bytes output in each class.

Table 193 describes significant fields commonly shown in the displays. The fields in the table are grouped according to the relevant QoS feature.
Table 193 show policy-map interface Field Descriptions1
|
|
Fields Associated with Classes or Service Policies
|
Service-policy output |
Name of the output service policy applied to the specified interface or VC. |
Class-map |
Class of traffic being displayed. Output is displayed for each configured class in the policy. The choice for implementing class matches (for example, match-all or match-any) can also appear next to the traffic class. |
packets and bytes |
Number of packets (also shown in bytes) identified as belonging to the class of traffic being displayed. |
offered rate |
Rate, in kbps, of packets coming in to the class. Note If the packets are compressed over an outgoing interface, the improved packet rate achieved by packet compression is not reflected in the offered rate. Also, if the packets are classified before they enter a combination of tunnels (for example, a generic routing encapsulation (GRE) tunnel and an IP Security (IPSec) tunnel), the offered rate does not include all the extra overhead associated with tunnel encapsulation in general. Depending on the configuration, the offered rate may include no overhead, may include the overhead for only one tunnel encapsulation, or may include the overhead for all tunnel encapsulations. In most of the GRE and IPSec tunnel configurations, the offered rate includes the overhead for GRE tunnel encapsulation only. |
drop rate |
Rate, in kbps, at which packets are dropped from the class. The drop rate is calculated by subtracting the number of successfully transmitted packets from the offered rate. |
Note In distributed architecture platforms (such as the Cisco 7500 series platform), the value of the transfer rate, calculated as the difference between the offered rate and the drop rate counters, can sporadically deviate from the average by up to 20 percent or more. This can occur while no corresponding burst is registered by independent traffic analyser equipment. |
Match |
Match criteria specified for the class of traffic. Choices include criteria such as IP precedence, IP differentiated services code point (DSCP) value, Multiprotocol Label Switching (MPLS) experimental (EXP) value, access groups, and QoS groups. For more information about the variety of match criteria that are available, see the "Classifying Network Traffic" module in the Cisco IOS Quality of Service Solutions Configuration Guide. |
Fields Associated with Queueing (if Enabled)
|
Output Queue |
The weighted fair queueing (WFQ) conversation to which this class of traffic is allocated. |
Bandwidth |
Bandwidth, in either kbps or percentage, configured for this class and the burst size. |
pkts matched/bytes matched |
Number of packets (also shown in bytes) matching this class that were placed in the queue. This number reflects the total number of matching packets queued at any time. Packets matching this class are queued only when congestion exists. If packets match the class but are never queued because the network was not congested, those packets are not included in this total. However, if process switching is in use, the number of packets is always incremented even if the network is not congested. |
depth/total drops/no-buffer drops |
Number of packets discarded for this class. No-buffer indicates that no memory buffer exists to service the packet. |
Fields Associated with Weighted Random Early Detection (WRED) (if Enabled)
|
exponential weight |
Exponent used in the average queue size calculation for a WRED parameter group. |
mean queue depth |
Average queue depth based on the actual queue depth on the interface and the exponential weighting constant. It is a fluctuating average. The minimum and maximum thresholds are compared against this value to determine drop decisions. |
class |
IP precedence level. |
Transmitted pkts/bytes |
Number of packets (also shown in bytes) passed through WRED and not dropped by WRED. Note If there is insufficient memory in the buffer to accommodate the packet, the packet can be dropped after the packet passes through WRED. Packets dropped because of insufficient memory in the buffer (sometimes referred to as "no-buffer drops") are not taken into account by the WRED packet counter. |
Random drop pkts/bytes |
Number of packets (also shown in bytes) randomly dropped when the mean queue depth is between the minimum threshold value and the maximum threshold value for the specified IP precedence level. |
Tail drop pkts/bytes |
Number of packets dropped when the mean queue depth is greater than the maximum threshold value for the specified IP precedence level. |
Minimum thresh |
Minimum threshold. Minimum WRED threshold in number of packets. |
Maximum thresh |
Maximum threshold. Maximum WRED threshold in number of packets. |
Mark prob |
Mark probability. Fraction of packets dropped when the average queue depth is at the maximum threshold. |
Fields Associated with Traffic Shaping (if Enabled)
|
Target Rate |
Rate used for shaping traffic. |
Byte Limit |
Maximum number of bytes that can be transmitted per interval. Calculated as follows: ((Bc+Be) /8) x 1 |
Sustain bits/int |
Committed burst (Bc) rate. |
Excess bits/int |
Excess burst (Be) rate. |
Interval (ms) |
Time interval value in milliseconds (ms). |
Increment (bytes) |
Number of credits (in bytes) received in the token bucket of the traffic shaper during each time interval. |
Queue Depth |
Current queue depth of the traffic shaper. |
Packets |
Total number of packets that have entered the traffic shaper system. |
Bytes |
Total number of bytes that have entered the traffic shaper system. |
Packets Delayed |
Total number of packets delayed in the queue of the traffic shaper before being transmitted. |
Bytes Delayed |
Total number of bytes delayed in the queue of the traffic shaper before being transmitted. |
Shaping Active |
Indicates whether the traffic shaper is active. For example, if a traffic shaper is active, and the traffic being sent exceeds the traffic shaping rate, a "yes" appears in this field. |
Precedence-Based Aggregate WRED on ATM Shared Port Adapter: Example
The following sample output of the show policy-map interface command displays the statistics for the ATM shared port adapter interface 4/1/0.10, to which a service policy called prec-aggr-wred (configured as shown below) is attached. Because aggregate WRED has been enabled on this interface, the class through Mark Prob statistics are aggregated by subclasses. See Table 194 for an explanation of the significant fields that commonly appear in the command output.

Frame Relay Voice-Adaptive Traffic-Shaping: Example
The following sample output shows that Frame Relay voice-adaptive traffic shaping is currently active and has 29 seconds left on the deactivation timer. With traffic shaping active and the deactivation time set, this means that the current sending rate on DLCI 201 is minCIR, but if no voice packets are detected for 29 seconds, the sending rate will increase to CIR.
Note
In HQF images for Cisco IOS Releases 12.4(20)T and later, the packets delayed and bytes delayed counters were removed for traffic shaping classes.

The sample output from show policy-map interface command shows the following:
•
59679 packets were marked as conforming packets (that is, packets conforming to the CIR) and were transmitted unaltered.
•
59549 packets were marked as exceeding packets (that is, packets exceeding the CIR but not exceeding the PIR). Therefore, the IP Precedence value of these packets was changed to an IP Precedence level of 4, the discard eligibility (DE) bit was set to 1, and the packets were transmitted with these changes.
•
53758 packets were marked as violating packets (that is, exceeding the PIR). Therefore, the IP Precedence value of these packets was changed to an IP Precedence level of 2, the DE bit was set to 1, and the packets were transmitted with these changes.
Note
Actions are specified by using the action argument of the police command. For more information about the available actions, see the police command reference page.

In this example, the CIR and PIR are displayed in bps, and both the committed burst (bc) and excess burst (be) are displayed in bits.
The CIR, PIR bc, and be are calculated on the basis of the formulas described below.
Formula for Calculating the CIR: Example
When calculating the CIR, the following formula is used:
•
CIR percentage specified (as shown in the output from the show policy-map command) * bandwidth (BW) of the interface (as shown in the output from the show interfaces command) = total bits per second
According to the output from the show interfaces command for the serial 2/0 interface, the interface has a bandwidth (BW) of 2048 kbps.
Router# show interfaces serial2/0
Serial2/0 is administratively down, line protocol is down
Hardware is M4T
MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec, rely 255/255, load 1/255
The following values are used for calculating the CIR:
20 % * 2048 kbps = 409600 bps
Formula for Calculating the PIR: Example
When calculating the PIR, the following formula is used:
•
PIR percentage specified (as shown in the output from the show policy-map command) * bandwidth (BW) of the interface (as shown in the output from the show interfaces command) = total bits per second
According to the output from the show interfaces command for the serial 2/0 interface, the interface has a bandwidth (BW) of 2048 kbps.
Router# show interfaces serial2/0
Serial2/0 is administratively down, line protocol is down
Hardware is M4T
MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec, rely 255/255, load 1/255
The following values are used for calculating the PIR:
40 % * 2048 kbps = 819200 bps
Note
Discrepancies between this total and the total shown in the output from the show policy-map interface command can be attributed to a rounding calculation or to differences associated with the specific interface configuration.
Formula for Calculating the Committed Burst (bc): Example
When calculating the bc, the following formula is used:
•
The bc in milliseconds (as shown in the show policy-map command) * the CIR in bits per seconds = total number bytes
The following values are used for calculating the bc:
300 ms * 409600 bps = 15360 bytes
Formula for Calculating the Excess Burst (be): Example
When calculating the bc and the be, the following formula is used:
•
The be in milliseconds (as shown in the show policy-map command) * the PIR in bits per seconds = total number bytes
The following values are used for calculating the be:
400 ms * 819200 bps = 40960 bytes

Bandwidth Estimation: Example
The following sample output from the show policy-map interface command displays statistics for the Fast Ethernet 0/1 interface on which bandwidth estimates for quality of service (QoS) targets have been generated.
The Bandwidth Estimation section indicates that bandwidth estimates for QoS targets have been defined. These targets include the packet loss rate, the packet delay rate, and the timeframe in milliseconds. Confidence refers to the drop-one-in value (as a percentage) of the targets. Corvil Bandwidth means the bandwidth estimate in kilobits per second.
When no drop or delay targets are specified, "none specified, falling back to drop no more than one packet in 500" appears in the output.

Packets Matched on the Basis of VLAN ID Number: Example
Note
As of Cisco IOS Release 12.2(31)SB2, matching packets on the basis of VLAN ID numbers is supported on the Catalyst 1000 platform only.
The following is a sample configuration in which packets are matched and classified on the basis of the VLAN ID number. In this sample configuration, packets that match VLAN ID number 150 are placed in a class called "class1."
Class Map match-all class1 (id 3)
Class1 is then configured as part of the policy map called "policy1." The policy map is attached to Fast Ethernet subinterface 0/0.1.
The following sample output of the show policy-map interface command displays the packet statistics for the policy maps attached to Fast Ethernet subinterface 0/0.1. It displays the statistics for policy1, in which class1 has been configured.

Command History
|
|
12.2(28)SB |
This command was introduced. |
12.2(33)SRB |
This command was integrated into Cisco IOS Release 12.2(33)SRB. |
12.2(33)SXH |
This command was integrated into Cisco IOS Release 12.2(33)SXH. |
12.4(20)T |
This command was integrated into Cisco IOS Release 12.4(20)T. |
Usage Guidelines
The show policy-map interface brief command displays the name of the active policy maps and the interfaces to which those policy maps are attached. An active policy map is one that is attached to an interface.
The optional keywords and arguments allow you to tailor the information displayed about VPNs, time stamps, and user IDs.
If you do not specify any optional keywords or arguments, all policy maps (even those that are not active) are displayed.
VPN Information Reported
The show policy-map interface brief command can be used for VRF interfaces in applications that use VPNs. To specify VRF interfaces, use the vrf keyword with the vrf-id argument.
Time-stamp and User ID Information Reported
If the optional timestamp keyword is used with the show policy-map interface brief command, the time and date when a policy map was attached to an interface appear in the display. In addition to the time and date information, the name (that is, the user ID) of the person who attached the policy map to the interface will be displayed.
Note
If the network software is reloaded (reinstalled), the time-stamp information (the time and date information) obtained will not be retained for any of the policy maps attached to interfaces on the network. Instead, the time and date information displayed will be the time and date when the software was reloaded.
Method for Obtaining User Information
The user information included in the display is obtained from the information that you enter when you log in to the router. For example, if you are using the SSH Secure Shell utility to log in to a router, you would typically enter your username and password. However, it is not always possible to obtain the user information. Instances where user information cannot be obtained include the following:
•
Not all routers require user information when you log in. Therefore, you may not be prompted to enter your username when you log in to a router.
•
If you are connecting to a console port using the Telnet utility in a DOS environment, you do not need to enter user information.
•
The user information cannot be retrieved because of system constraints or other factors.
If the user information cannot be obtained, the words "by unknown" will be displayed.
Hierarchical Policy Map Information
For a hierarchical policy map structure, only the information about the parent policy maps is displayed. Information about child policy maps is not displayed.
ATM PVCs
For ATM permanent virtual circuits (PVCs), policy maps do not remain associated with the interface if the ATM PVC is not working properly (that is, the ATM PVC is "down"). Therefore, if an ATM PVC is down, and a policy map is attached to an interface, the show policy-map interface brief command does not include information about the policy maps in the command output.

In some network configurations, the policy map may be attached to the interface initially, and then at a later time, the interface can be configured to act as a VRF interface. In this kind of network configuration, the time-stamp information displays the time when the policy map was attached to the interface. The display does not include the time when the interface was configured to act as a VRF interface. Displaying only the time when the policy map is attached to the interface also applies to the scenarios that are described in the following paragraph for other network configurations.
In other network configurations, a VRF may be attached to multiple interfaces as described in the following scenarios:
•
The policy map is also attached to both the interfaces and the VRFs. In this network configuration, all the interfaces should be shown in the display for the VRF, under the policy map name, as follows:
Service-policy input: policyname1

Fields Associated with Classes or Service Policies
|
Service-policy output |
Name of the output service policy applied to the specified interface or VC. |
Class-map |
Class of traffic being displayed. Output is displayed for each configured class in the policy. The choice for implementing class matches (for example, match-all or match-any) can also appear next to the traffic class. |
packets and bytes |
Number of packets (also shown in bytes) identified as belonging to the class of traffic being displayed. |
offered rate |
Rate, in kbps, of packets coming in to the class. Note If the packets are compressed over an outgoing interface, the improved packet rate achieved by packet compression is not reflected in the offered rate. Also, if the packets are classified before they enter a combination of tunnels (for example, a generic routing encapsulation (GRE) tunnel and an IP Security (IPSec) tunnel), the offered rate does not include all the extra overhead associated with tunnel encapsulation in general. Depending on the configuration, the offered rate may include no overhead, may include the overhead for only one tunnel encapsulation, or may include the overhead for all tunnel encapsulations. In most of the GRE and IPSec tunnel configurations, the offered rate includes the overhead for GRE tunnel encapsulation only. |
drop rate |
Rate, in kbps, at which packets are dropped from the class. The drop rate is calculated by subtracting the number of successfully transmitted packets from the offered rate. |
Match |
Match criteria specified for the class of traffic. Choices include criteria such as IP precedence, IP differentiated services code point (DSCP) value, Multiprotocol Label Switching (MPLS) experimental (EXP) value, access groups, and QoS groups. For more information about the variety of match criteria that are available, see the "Classifying Network Traffic" module in the Cisco IOS Quality of Service Solutions Configuration Guide. |
Fields Associated with Queueing (if Enabled)
|
Output Queue |
The weighted fair queueing (WFQ) conversation to which this class of traffic is allocated. |
Bandwidth |
Bandwidth, in either kbps or percentage, configured for this class and the burst size. |
pkts matched/bytes matched |
Number of packets (also shown in bytes) matching this class that were placed in the queue. This number reflects the total number of matching packets queued at any time. Packets matching this class are queued only when congestion exists. If packets match the class but are never queued because the network was not congested, those packets are not included in this total. However, if process switching is in use, the number of packets is always incremented even if the network is not congested. |
depth/total drops/no-buffer drops |
Number of packets discarded for this class. No-buffer indicates that no memory buffer exists to service the packet. |
Fields Associated with Weighted Random Early Detection (WRED) (if Enabled)
|
exponential weight |
Exponent used in the average queue size calculation for a WRED parameter group. |
mean queue depth |
Average queue depth based on the actual queue depth on the interface and the exponential weighting constant. It is a fluctuating average. The minimum and maximum thresholds are compared against this value to determine drop decisions. |
class |
IP precedence level. |
Transmitted pkts/bytes |
Number of packets (also shown in bytes) passed through WRED and not dropped by WRED. Note If there is insufficient memory in the buffer to accommodate the packet, the packet can be dropped after the packet passes through WRED. Packets dropped because of insufficient memory in the buffer (sometimes referred to as "no-buffer drops") are not taken into account by the WRED packet counter. |
Random drop pkts/bytes |
Number of packets (also shown in bytes) randomly dropped when the mean queue depth is between the minimum threshold value and the maximum threshold value for the specified IP precedence level. |
Tail drop pkts/bytes |
Number of packets dropped when the mean queue depth is greater than the maximum threshold value for the specified IP precedence level. |
Minimum thresh |
Minimum threshold. Minimum WRED threshold in number of packets. |
Maximum thresh |
Maximum threshold. Maximum WRED threshold in number of packets. |
Mark prob |
Mark probability. Fraction of packets dropped when the average queue depth is at the maximum threshold. |
Fields Associated with Traffic Shaping (if Enabled)
|
Target Rate |
Rate used for shaping traffic. |
Byte Limit |
Maximum number of bytes that can be transmitted per interval. Calculated as follows: ((Bc+Be) /8) x 1 |
Sustain bits/int |
Committed burst (Bc) rate. |
Excess bits/int |
Excess burst (Be) rate. |
Interval (ms) |
Time interval value in milliseconds (ms). |
Increment (bytes) |
Number of credits (in bytes) received in the token bucket of the traffic shaper during each time interval. |
Queue Depth |
Current queue depth of the traffic shaper. |
Packets |
Total number of packets that have entered the traffic shaper system. |
Bytes |
Total number of bytes that have entered the traffic shaper system. |
Packets Delayed |
Total number of packets delayed in the queue of the traffic shaper before being transmitted. |
Bytes Delayed |
Total number of bytes delayed in the queue of the traffic shaper before being transmitted. |
Shaping Active |
Indicates whether the traffic shaper is active. For example, if a traffic shaper is active, and the traffic being sent exceeds the traffic shaping rate, a "yes" appears in this field. |

|
SSS session identifier |
Unique session identifier. |
Service-policy output |
Name of the output service policy applied to the specified interface or virtual circuit (VC). |
Class-map |
Class of traffic being displayed. Output is displayed for each configured class in the policy. The choice for implementing class matches (for example, match-all or match-any) can also appear next to the traffic class. |
packets and bytes |
Number of packets (also shown in bytes) identified as belonging to the class of traffic being displayed. |
offered rate |
Rate, in bps, of packets coming in to the class. Note If the packets are compressed over an outgoing interface, the improved packet rate achieved by packet compression is not reflected in the offered rate. Also, if the packets are classified before they enter a combination of tunnels (for example, a generic routing encapsulation [GRE] tunnel and an IP Security [IPsec] tunnel), the offered rate does not include all the extra overhead associated with tunnel encapsulation in general. Depending on the configuration, the offered rate may include no overhead, may include the overhead for only one tunnel encapsulation, or may include the overhead for all tunnel encapsulations. In most of the GRE and IPsec tunnel configurations, the offered rate includes the overhead for GRE tunnel encapsulation only. |
drop rate |
Rate, in bps, at which packets are dropped from the class. The drop rate is calculated by subtracting the number of successfully transmitted packets from the offered rate. |
Match |
Match criteria specified for the class of traffic. Choices include criteria such as IP precedence, IP differentiated services code point (DSCP) value, Multiprotocol Label Switching (MPLS) experimental (EXP) value, access groups, and QoS groups. For more information about the variety of availablematch criteria options, see the "Applying QoS Features Using the MQC" module of the Cisco IOS Quality of Service Solutions Configuration Guide. |
QoS Set |
Indicates that packet marking is in place. |
dscp |
Value used in packet marking. |

The application (or client) associated with the QBM pool. This string is provided by the client and as a result, the client chooses the string, not QBM. For example, RSVP 3175 AggResv 192.168.40.1->192.168.50.1_ef(46) means the QBM pool is associated with the RSVP aggregate reservation with source endpoint (aggregator) having IP address 192.168.40.1, destination endpoint (deaggregator) having IP address 192.168.50.1, and differentiated services code point (DSCP) expedited forwarding (EF). |
Minimum |
The pool's minimum bandwidth guarantee. (Units may vary.) |
Oper Status |
Status of the application. Values are the following: • OPERATIONAL—Application is enabled. • NON-OPERATIONAL—Application is disabled. |
Oper Minimum |
Defines the minimum bandwidth guarantee that the pool is able to enforce. This value may differ from the pool's minimum bandwidth guarantee because of operational conditions. For example, if the pool is associated with an interface and the interface is down, its Oper Status is NON-OPERATIONAL, then the operational minimum is N/A. |
Used Bandwidth |
The bandwidth reserved by applications/clients using this pool. N/A displays instead of 0 when the pool's Oper Status is NON-OPERATIONAL. |
The following sample output is from the show qbm pool command with a specified pool ID:
Router# show qbm pool id 0x000000006
Associated object: 'RSVP 3175 AggResv 192.168.40.1->192.168.50.1_ef(46)'

show queue
Note
Effective with Cisco IOS XE Release 2.6, Cisco IOS Release 15.0(1)S, and Cisco IOS Release 15.1(3)T, the show queue command is hidden. Although this command is still available in Cisco IOS software, the CLI interactive Help does not display it if you attempt to view it by entering a question mark at the command line.
This command will be completely removed in a future release, which means that you will need to use the appropriate replacement command (or sequence of commands). For more information (including a list of replacement commands), see the Legacy QoS Command Deprecation feature document in the Cisco IOS XE Quality of Service Solutions Configuration Guide or the Legacy QoS Command Deprecation feature document in the Cisco IOS Quality of Service Solutions Configuration Guide.
Note
Effective with Cisco IOS XE Release 3.2S, the show queue command is replaced by a modular QoS CLI (MQC) command (or sequence of MQC commands). For the appropriate replacement command (or sequence of commands), see the Legacy QoS Command Deprecation feature document in the Cisco IOS XE Quality of Service Solutions Configuration Guide.
To display the contents of packets inside a queue for a particular interface or virtual circuit (VC), use the show queue command in user EXEC or privileged EXEC mode.
show queue interface-name interface-number [queue-number] [vc [vpi/] vci]
Syntax Description
interface-name |
The name of the interface. |
interface-number |
The number of the interface. |
queue-number |
(Optional) The number of the queue. The queue number is a number from 1 to 16. |
vc |
(Optional) For ATM interfaces only, shows the fair queueing configuration for a specified permanent virtual circuit (PVC). The name can be up to 16 characters long. |
vpi/ |
(Optional) ATM network virtual path identifier (VPI) for this PVC. The absence of the "/" and a vpi value defaults the vpi value to 0. On the Cisco 7200 and Cisco 7500 series routers, this value ranges from 0 to 255. The vpi and vci arguments cannot both be set to 0; if one is 0, the other cannot be 0. If this value is omitted, information for all VCs on the specified ATM interface or subinterface is displayed. |
vci |
(Optional) ATM network virtual channel identifier (VCI) for this PVC. This value ranges from 0 to 1 less than the maximum value set for this interface by the atm vc-per-vp command. Typically, lower values 0 to 31 are reserved for specific traffic (F4 Operation, Administration, and Maintenance (OAM), switched virtual circuit (SVC) signalling, Integrated Local Management Interface (ILMI), and so on) and should not be used. The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single link, not throughout the ATM network, because it has local significance only. The vpi and vci arguments cannot both be set to 0; if one is 0, the other cannot be 0. |

Flow-Based WRED: Example
The following is sample output from the show queueing random-detect command. The output shows that the interface is configured for flow-based WRED to ensure fair packet drop among flows. The random-detect flow average-depth-factor command was used to configure a scaling factor of 8 for this interface. The scaling factor is used to scale the number of buffers available per flow and to determine the number of packets allowed in the output queue of each active flow before the queue is susceptible to packet drop. The maximum flow count for this interface was set to 16 by the random-detect flow count command.

Usage Guidelines
Cisco 7600 Series Routers
The pos, atm, and ge-wan interfaces are supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2 only.
The type number argument used with the interface keyword designates the module and port number. Valid values depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 1 to 13 and valid values for the port number are from 1 to 48.
The show queueing interface command does not display the absolute values that are programmed in the hardware. Use the show qm-sp port-data command to verify the values that are programmed in the hardware.
Catalyst 6500 Series Switches
In Cisco IOS Release 12.2(33)SXI and later releases, the optional detailed keyword is available. The show queueing interface detailed command output includes the following information:
•
Display of the last 30-second counters.
•
Display of the peak 30-second counters over the last 5 minutes.
•
Display of the 5-minute average and peak bps rates.
•

Note
Effective with Cisco IOS Release 15.0(1)S and Cisco IOS Release 15.1(3)T, the show random-detect-group command is hidden. Although this command is still available in Cisco IOS software, the CLI interactive Help does not display it if you attempt to view it by entering a question mark at the command line.
This command will be completely removed in a future release, which means that you will need to use the appropriate replacement command (or sequence of commands). For more information (including a list of replacement commands), see the Legacy QoS Command Deprecation feature document in the Cisco IOS Quality of Service Solutions Configuration Guide.
To display the Weighted Random Early Detection (WRED) or distributed WRED (DWRED) parameter group, use the show random-detect-group command in privileged EXEC mode.

Usage Guidelines
WRED is a congestion avoidance mechanism that slows traffic by randomly dropping packets when there is congestion. DWRED is similar to WRED but uses the Versatile Interface Processor (VIP) instead of the Route Switch Processor (RSP). WRED and DWRED are most useful when the traffic uses protocols such as TCP that respond to dropped packets by decreasing the transmission rate.
Examples
The following example displays the current settings of the DWRED group called group-name:
Router# show random-detect-group group-name
class min-threshold max-threshold mark-probablity

|
|
exponential weight |
Exponential weight factor for the average queue size calculation for a WRED parameter group. |
class |
Policy map class name. |
min-threshold |
Minimum threshold in number of packets. The value range of this argument is from 1 to 4096. When the average queue length reaches the minimum threshold, WRED randomly drops some packets with the specified IP Precedence. |
max-threshold |
Maximum threshold in number of packets. The value range of this argument is from the value of the min-threshold argument to 4096. When the average queue length exceeds the maximum threshold, WRED drops all packets with the specified IP Precedence. |
mark-probability |
Denominator for the fraction of packets dropped when the average queue depth is at the minimum threshold. For example, if the denominator is 512, 1 out of every 512 packets is dropped when the average queue is at the minimum threshold. The value range is from 1 to 65536. The default is 10; 1 out of every 10 packets is dropped at the minimum threshold. |
rsvp |
Indicates Resource Reservation Protocol (RSVP) traffic. |
