This command displays all configuration information for the specified policy. The policyname is the name of an existing DiffServ policy.
| Format | show policy-map [policyname] |
| Mode | Privileged EXEC |
If the Policy Name is specified the following fields are displayed:
| Policy Name | The name of this policy. |
| Policy Type | The policy type (only inbound policy definitions are supported for this platform.) |
| Class Members | The class that is a member of the policy. |
The following information is repeated for each class associated with this policy (only those policy attributes actually configured are displayed):
| Assign Queue | Directs traffic stream to the specified QoS (Quality of Service) queue. This allows a traffic classifier to specify which one of the supported hardware queues are used for handling packets belonging to the class. |
| Class Name | The name of this class. |
| Committed Burst Size (KB) | The committed burst size, used in simple policing. |
| Committed Rate (Kbps) | The committed rate, used in simple policing. |
| Conform Action | The current setting for the action taken on a packet considered to conform to the policing parameters. This is not displayed if policing is not in use for the class under this policy. |
| Conform Color Mode | The current setting for the color mode. Policing uses either color blind or color aware mode. Color blind mode ignores the coloration (marking) of the incoming packet. Color aware mode takes into consideration the current packet marking when determining the policing outcome. |
| Conform COS | The CoS (Class of Service) mark value if the conform action is set-cos-transmit. |
| Conform DSCP Value | The DSCP mark value if the conform action is set-dscp-transmit. |
| Conform IP Precedence Value | The IP Precedence mark value if the conform action is set-prec-transmit. |
| Drop | Drop a packet upon arrival. This is useful for emulating access control list operation using DiffServ, especially when DiffServ and ACL (Access Control List) cannot co-exist on the same interface. |
| Exceed Action | The action taken on traffic that exceeds settings that the network administrator specifies. |
| Exceed Color Mode | The current setting for the color of exceeding traffic that you can optionally specify. |
| Mark CoS | The class of service value that is set in the 802.1p header of inbound packets. This is not displayed if the mark cos was not specified. |
| Mark CoS as Secondary CoS | The secondary 802.1p priority value (second/inner VLAN tag. Same as CoS (802.1p) marking, but the dot1p value used for remarking is picked from the dot1p value in the secondary (that is, inner) tag of a double-tagged packet. |
| Mark IP DSCP | The mark/re-mark value used as the DSCP for traffic matching this class. This is not displayed if mark ip description is not specified. |
| Mark IP Precedence | The mark/re-mark value used as the IP Precedence for traffic matching this class. This is not displayed if mark ip precedence is not specified. |
| Non-Conform Action | The current setting for the action taken on a packet considered to not conform to the policing parameters. This is not displayed if policing not in use for the class under this policy. |
| Non-Conform COS | The CoS mark value if the non-conform action is set-cos-transmit. |
| Non-Conform DSCP Value | The DSCP mark value if the non-conform action is set-dscp-transmit. |
| Non-Conform IP Precedence Value | The IP Precedence mark value if the non-conform action is set-prec-transmit. |
| Peak Rate | Guarantees a committed rate for transmission, but also transmits excess traffic bursts up to a user-specified peak rate, with the understanding that a downstream network element (such as the next hop‘s policer) might drop this excess traffic. Traffic is held in queue until it is transmitted or dropped (per type of queue depth management.) Peak rate shaping can be configured for the outgoing transmission stream for an AF (Assured Forwarding) traffic class (although average rate shaping could also be used.) |
| Peak Burst Size | (PBS). The network administrator can set the PBS as a means to limit the damage expedited forwarding traffic could inflict on other traffic (for example, a token bucket rate limiter) Traffic that exceeds this limit is discarded. |
| Policing Style | The style of policing, if any, used (simple). |
If the Policy Name is not specified this command displays a list of all defined DiffServ policies. The following fields are displayed:
| Policy Name | The name of this policy. (The order in which the policies are displayed is not necessarily the same order in which they were created.) |
| Policy Type | The policy type (Only inbound is supported). |
| Class Members | List of all class names associated with this policy. |
The following example shows CLI display output including the mark-cos-as-sec-cos option specified in the policy action.
