Disable capturing using the no form of this command. The buffer size supports a maximum value between 40 MB (the default) and 100 MB. The capture buffers are cyclic and reaching the limit prompts the system to overwrite the oldest PDUs when new ones are received for a given neighbor or direction. Setting the buffer size to a value lower than the current max, might cause captured PDUs to be freed to set the new limit. Note: Memory on RP1 is not pre-allocated, and is allocated only when a PDU needs to be captured. Use the command capture bgp-pdu max-buffer-size to change the maximum buffer size. View the captured PDUs using the command show capture bgp-pdu neighbor.
