To display the configuration of an IP policy list that contains inactive references to the interface to which it is attached:

    host1#show policy-list pv4

                                     Policy Table
                                      ------ -----

#### Meaning

Table 42 lists the show policy-list command output fields.

Table 42: show policy-list Output Fields

Field Name | Field Description
--- | ---
Policy | Name of the policy list.
Administrative state | For SNMP use; state is enabled when the policy list is created. Users modifying the policy list commands via telnet see the state as disabled. Modifications of a policy are not applied to an interface until the administrative state is first disabled and then reenabled.
Reference count | Number of attachments to interfaces or profiles. An asterisk enclosed in parenthesis (*), if displayed, denotes that the policy contains inactive references to interfaces. The absence of an asterisk denotes that all the attachments of this policy to the specified number of interfaces are active.
Atm cell mode | State of mode for ATM cell tax used in rate calculations.
Referenced by interfaces | List of interfaces to which policy is attached and is active; indicates whether the attachment is at input or output of interface.
Referenced by profiles | List of profiles to which policy is attached; indicates whether the attachment is at input, secondary-input, or output of interface created by the profile.
Referenced by merge policies | List of merged policies.
Referenced by component policies | List of component policies.
Classifier control list | Name of the classifier control list containing policy rules and the precedence assigned to the classifier control list.
Statistics | Enabled, disabled
Parent group | Name of the parent group.
Rule types are: |
filter | Filter policy action
exception http-redirect | HTTP redirect policy action
forward | Forward policy action
next-interface | Next-interface policy action
next-hop | Next-hop policy action
rate-limit-profile | Rate-limit-profile policy action
color | Color of a packet; green, yellow, or red
traffic-class | Traffic class in a policy list
log | Log policy action
mark tos | ToS byte in the IP header to a specified value
mark DS field | DS field value in the IP header to a specified value
mark TC precedence | Traffic class value in the IPv6 header to a specified value
mark EXP | Value assigned to EXP bits action
mark user priority | Value assigned to 802.1p VLAN user priority bit
mark DE | DE bit action
Rule status | Indicates whether the rule is suspended.
