- LTM/DNS monitors created via tmsh batch/transactions improperly escape newline characters. - Expected escaping: \r\n - Actual escaping: \\r\\n - Impact: The URI sent is not correct,
Cannot use batch/transaction mode in TMSH to create LTM or DNS monitors. Cannot use LTM or DNS monitors created using batch/transaction mode in tmsh.
When creating LTM or DNS monitors through batch/transaction mode when strings contain newline characters. For example, using the following commands to batch-create: create gtm monitor http one_test_mon { send "GET / HTTP/1.0\r\nHost: abc.example.com\r\nUser-Agent: slb-healthcheck\r\nConnection: Close\r\n\r\n" recv "200"} submit cli transaction list gtm monitor http one_test_mon The system creates the following monitor: gtm monitor http one_test_mon { defaults-from http destination *:* interval 30 probe-timeout 5 recv 200 send "GET / HTTP/1.0\\r\\nHost: abc.example.com\\r\\nUser-Agent: slb-healthcheck\\r\\nConnection: Close\\r\\n\\r\\n"
Create the monitor directly in tmsh without using batch/transaction mode.
When creating LTM or DNS monitors through batch/transaction mode newlines are now properly escaped.
