    Release Information

    Statement introduced in Junos OS Mobility Release 11.2W.


    Specify the size of the reserved wired process memory (Big Translation Lookaside Buffer [BTLB]) to be used by service applications. Currently, stateful firewall and mobility are the service applications supported. You can also configure object cache. If this setting is changed, the PIC reboots.

    The wired process memory, or BTLB, is memory used by the operating system that is pretty much "off limits" to another application. If wired process memory is exhausted, the processes use unwired memory.

    • BTLB is supported only on 16-GB cards. In addition, BTLB is supported only with total-wired-memory of 14,336 MB.
    • To use wired memory, you need to configure both wired-max-processes and wired-process-mem-size.

      Note: For mobility, we support only a wired-max-processes value of 8, and a wired-process-mem-size value of 1024.


    memory-size—Total wired process memory to be reserved.

    Range: 0 through 2048 MB
    Default: 0, which indicates that no memory is reserved by service applications.
