Data-Fill - HP MSR1003-8S Command Reference Manual

Usage guidelines
Execute this command to specify the community name on the NQA client if the SNMP agent runs
SNMPv1 or SNMPv2c. The specified community name must be the read-only community name that has
been configured on the SNMP agent.
If the SNMP agent runs SNMPv3, you do not need to specify the community name on the NQA client.
For security purposes, the community name configured in plain text or cipher text is saved in cipher text.
Examples
# Specify readaccess as the community name for SNMPv1 and SNMPv2c probe packets.
<Sysname> system-view
[Sysname] nqa entry admin test
[Sysname-nqa-admin-test] type snmp
[Sysname-nqa-admin-test-snmp] community read simple readaccess

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 set the payload size to 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 depends on the operation type.
• 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. The string fills the remaining part of payload.
