• The max buffer size is reduced. (This may cause PDUs to be cleared depending on the buffer space consumed and the new limit.) Examples of Capturing PDUs To change the maximum buffer size, use the capture bgp-pdu max-buffer-size command. To view the captured PDUs, use the show capture bgp-pdu neighbor command.
