Hierarchy Level


Specify the amount of time before the last active port block is released. This option is used with the active-block-timeout option at [edit security nat source pool port block-allocation] hierarchy level. When the active-block-timeout option is set to 0 (zero), port blocks are filled completely before a new port block is allocated. However, the last port block remains active indefinitely. The last-block-recycle-timeout option allows you to release the last active block when there are no live sessions remaining. If the active-block-timeout option is set to anything but 0, the last-block-recycle-timeout option is not necessary.


timeout-interval—Number of seconds before the active block is released.
