NQA commands data-fill Use data-fill to configure the string to be filled in the payload of each probe packet. Use undo data-fill to restore the default. Syntax data-fill string undo data-fill Default The string is the hexadecimal number 00010203040506070809. Views ICMP echo operation view, UDP echo operation view Predefined user roles network-admin Parameters string: Specifies a case-sensitive string of 1 to 200 characters. Usage guidelines If the payload length is smaller than the string length, only the first part of the string is filled. For example, if you configure the string as abcd and the payload size as 3 bytes, abc is filled. If the payload length is greater than the string length, the system fills the payload with the string cyclically until the payload is full. For example, if you configure the string as abcd and the payload size as 6 bytes, abcdab is filled. How the string is filled varies with operation types: • For the ICMP echo operation, the string fills the whole payload of an ICMP echo request. • For the UDP echo operation, the first five bytes of the payload of a UDP packet are for special purpose, so the string fills the remaining part of payload. Examples # Configure string abcd to be filled in the payload of an ICMP echo request. system-view [Sysname] nqa entry admin test [Sysname-nqa-admin-test] type icmp-echo [Sysname-nqa-admin-test-icmp-echo] data-fill abcd data-size Use data-size to configure the size of the payload in each ICMP echo request of the ICMP echo, or in each UDP packet of the UDP echo. 115
