topic in the platform-specific SPA software configuration guide for subslot information.
|
|
port
|
(CMTS and ATM shared port adapter only) Port or interface number. See the appropriate hardware manual for port information.
For SPAs, see the corresponding “Specifying the Interface Address” topics in the platform-specific SPA software configuration
guide.
|
|
.subinterface
|
(ATM shared port adapter only—Optional) Subinterface number. The number that precedes the period must match the number to
which this subinterface belongs. The range is 1 to 4,294,967,293.
|
|
type
|
Type of interface or subinterface whose policy configuration is to be displayed.
|
|
type-parameter
|
Port, connector, interface card number, class-map name or other parameter associated with the interface or subinterface type.
|
|
vc
|
(Optional) For ATM interfaces only, shows the policy configuration for a specified PVC.

vpi
/
|
(Optional) ATM network virtual path identifier (VPI) for this permanent virtual circuit (PVC). On the Cisco 7200 and 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.
The absence of both the forward slash (/ ) and a

[OAM], switched virtual circuit [SVC] signaling, 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.

Usage Guidelines
Cisco 3660, 3845, 7200, 7400, 7500, Cisco ASR 903 Series Routers, 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.
Examples
This section provides sample output from typical
show policy-map interface commands. Depending upon the interface or platform in use and the options enabled, the output you see may vary slightly from
the ones shown below.
Examples
The following sample output of the
show policy-map interface command displays the statistics for the serial 3/1 interface, to which a service policy called mypolicy (configured as shown
below) is attached. Weighted fair queueing (WFQ) has been enabled on this interface. See the table below for an explanation
of the significant fields that commonly appear in the command output.

The table below describes significant fields commonly shown in the displays. The fields in the table are grouped according
to the relevant QoS feature. A number in parentheses may appear next to the service-policy output name, class-map name, and
match criteria information. The number is for Cisco internal use only and can be disregarded.
Table 27. show policy-map interface Field Descriptions
|
Field
|
Description
|
|
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.
|
Examples
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 the table below for an explanation of the significant fields
that commonly appear in the command output.

Field
|
Description
|
|
exponential weight
|
Exponent used in the average queue size calculation for a Weighted Random Early Detection (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.
|
| Note
|
When Aggregate Weighted Random Early Detection (WRED) is enabled, the following WRED statistics will be aggregated based
on their subclass (either their IP precedence or differentiated services code point (DSCP) value).
|
|
|
class
|
IP precedence level or differentiated services code point (DSCP) value.
|
|
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 or DSCP value.
|
|
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 or DSCP value.
|
|
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.
|
Examples
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.

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.

|
|
Sent total
|
Count of every packet sent, both compressed packets and full-header packets.

|
|
bytes sent
|
Total number of bytes sent for both compressed and full-header packets.
|
|
efficiency improvement factor
|

|
The actual traffic rate (in bits per second) after the packets are compressed.
|
Note |
A number in parentheses may appear next to the service-policy output name and the class-map name. The number is for Cisco
internal use only and can be disregarded.

Field
|
Description
|
|
Service-policy input
|
Name of the input 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.

|
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.

Examples
The following is sample output from the
show policy-map interface command. This sample displays the statistics for the serial 2/0 interface on which traffic policing has been enabled. The
committed (conform) burst (bc) and excess (peak) burst (be) are specified in milliseconds (ms).
Router# show policy-map interface serial2/0

0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any (1055)
0 packets, 0 bytes
5 minute rate 0 bps
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.
Examples
When calculating the CIR, the following formula is used:
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
Examples
When calculating the PIR, the following formula is used:
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.
|
Examples
When calculating the bc, the following formula is used:
The following values are used for calculating the bc:
300 ms * 409600 bps = 15360 bytes
Examples
When calculating the bc and the be, the following formula is used:
The following values are used for calculating the be:
400 ms * 819200 bps = 40960 bytes
