Monitor Protocol

To capture packets on different interfaces (gr-instance aware), use the following command:

monitor protocol [ interface ] (capture-duration) (count) (level) (gr-instance)  

NOTES:

  • interface —Interface on which PCAP is captured.

    Example: sbi, pfcp, gtpu, gtpc, gtp, radius

  • list —Monitor protocol list files.

  • capture-duration —(Optional) Used to specify the duration in secs during which PCAP is captured. Default value is 300 secs.

  • pcap —(Optional) When set to yes, it enables PCAP file generation. By default, the value is "no" (disabled).

  • gr-instance —(Optional) Monitor subscriber for a given gr-instance only.

Example

The following is a configuration example.

monitor protocol interface sbi gr-instance 1
