The command "debug packet capture" is available in EXOS 15.4 and later to capture packets to/from the CPU in the CLI.
* It doesn't require to enable the debug mode. However, it is the hidden debug command that needs to be manually typed in the CLI as shown below.

 
# debug packet capture {ports <port_list>} {on|off} {file-name <file_name>} {count <number of packets>}

Use the following command to start capturing all packets to/from the CPU.
# debug packet capture on

Use the following command to stop the packet capture.
# debug packet capture off

Use the following command to capture 100 packets and automatically stop the packet capture (after 100 packets are captured).
# debug packet capture on count 100

Use the following command to capture 100 packets from the ports 1:1-1:2.
# debug packet capture port 1:1-2 on count 100

Use the following command to capture 100 packets from the ports 1:1 and 1:2, and save the capture in the "pktcapt001.pcap" file. 
# debug packet capture port 1:1-2 on file-name pktcapt001 count 100

The packet capture files are saved to internal memory. Use "ls /usr/local/tmp" or "ls internal-memory" to view the capture files:

 
# ls /usr/local/tmp
-rwxr-xr-x    1 root     0             352 Aug 20 22:16 2014-08-20_22-16-20_rx_tx.pcap
-rwxr-xr-x    1 root     0              67 Aug 20 22:17 2014-08-20_22-17-41_rx_tx.pcap
-rwxr-xr-x    1 root     0               5 Aug 20 22:25 2014-08-20_22-25-30_rx_tx.pcap
* Filenames will be autonamed if no filename is given. The capture files can be sent to a TFTP server for analysis.
