    show unified-edge ggsn-pgw ip-reassembly statistics

    Syntax

    show unified-edge ggsn-pgw ip-reassembly statistics<brief | detail><fpc-slot fpc-slot><inet><pic-slot pic-slot>

    Release Information

    Command introduced in Junos OS Mobility Release 11.2W.

    Description

    Display the IP reassembly statistics per services PIC. If the services PIC slot is not specified, then the statistics for all the services PICs are displayed.

    Options

    none

    (Same as brief) Display the IP reassembly statistics in brief.

    brief | detail

    (Optional) Display the specified level of output.

    Note: The brief option displays the aggregated statistics from each services PIC.

    fpc-slot fpc-slot

    (Optional) Display the IP reassembly statistics for the specified Flexible PIC Concentrator (FPC) slot number.

    inet

    (Optional) Display the IP reassembly for IPv4 packets.

    pic-slot pic-slot

    (Optional) Display the IP reassembly statistics for the specified PIC slot number. You must first specify an FPC slot number before specifying the PIC slot number.
