    Table 1: show pfe tcam usage Output Fields

    Field Name

    Field Description

    App name

    Name of the application with TCAM resource usage errors

    Related-App-Name

    Name of the related applications for an application using the TCAM resource.

    Precedence

    Application priority

    State

    Status of the application. The status can be OK or FAILED.

    Tcam-stage

    Describes the stage (egress, ingress, and pre-ingress)

    Group

    Logical representation of one or more tcam-slices.

    Note: Tcam-slice represents the hardware TCAM block, where the TCAM lookup can happen in parallel.

    Mode

    Defines the matching capability of a given group. The following are the possible values for Mode:

    • SINGLE—TCAM space is single-wide. Single-wide modes is used to configure a TCAM entry from a single TCAM slice.
    • DOUBLE—TCAM space mode is double-wide. Double-wide mode is used to configure two TCAM slices using one TCAM entry from each TCAM slice.
    • DOUBLE(I)—TCAM space mode is double-wide intra-slice. Double-wide intra-slice mode is used to configure a TCAM slice to use two TCAM entries as a single entry.

    Tcam-Entries

    TCAM resource used by an application to achieve the functionality of the application.

    Counters

    Counter resource used by an application.

    Policers

    Policer resource used by an application.

    Free

    Available TCAM space.

    Used

    Number of resources used by application or group.

    Errors

    Number of errors occurred due to shortage of TCAM resources.

    Resource-Shortage

    Shortage of TCAM resources for an application

    Allocated

    Number of TCAM resources allocated for a group.

    Available

    Number of available TCAM resources for a group.

    Hw grps used

    Number of TCAM slices used by the group.

    Tcam apps

    Number of TCAM applications for a group.

    Tcam-slice represents the hardware TCAM block, where the TCAM lookup can happen in parallel. Tcam-group represents the logical representation of one or more tcam-slices.
