and saved into the RAM. Capturing packets can be stopped manually before 128 packets have been captured using the monitor capture stop command to halt packet capture. If capturing is in progress, the show monitor capture packets command displays only captured packets that have not yet been displayed during capturing session. If capturing is stopped, the first (after stopping) show monitor capture packets command displays packets which have not yet been displayed during capturing session. The next show monitor capture packets command displays all saved packets. If the capturing session is stopped automatically during the period packet display is in progress, the packets display continues until all saved packets are shown and then the buffer is cleared. The next invocation of the show capture packets command will not display any packets. Please note that this behavior is observed only if the capturing session is stopped automatically when the packet displaying is in progress. The in-memory capture can also be configured to wrap. This makes it possible to display more than 128 packets per capture session if the command show capture packets is periodically executed while capture is in progress. Saved packets that have been already displayed during the capturing session are overwritten in RAM by new captured packets if capturing is still in progress. In this manner, the limit of displaying 128 packets per session can be overcome (but only in monitor capture line wrap mode). Packets that have not been displayed are not overwritten. Capturing packets is stopped automatically when 128 packets are captured and have not yet been displayed during capturing session. It is guaranteed that no one packet will be lost (not be displayed or not be saved) when capturing is in progress. In this case, the last 128 packets are saved into the RAM and can be displayed many number of times by executing the command show monitor capture packets. If capturing is in progress and more than 128 packets are captured and the user configures no monitor capture line wrap mode, capturing is stopped automatically. No packets are lost when capturing is in progress. All captured packets can be displayed. No captured and not yet displayed packets are lost. Captured packets can be displayed when capturing is in progress or after the moment when capturing is stopped. Only packets saved in RAM (up to 128) can be displayed when capturing is stopped.
