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
