CLI "expect ?" will show both hex-regex and regex for user to configure, irrespective of type(ASCII
or HEX) of send-data configured. UDP probe is created using CLI with Send-data and Expect hex-regex
data with offset as given below:
switch/Admin(config)# probe udp test1
switch/Admin(config-probe-udp)# send-data "abcde"
switch/Admin(config-probe-udp)# expect ?
hex-regex Configure Hex data expected as response
regex Configure probe expected response
switch/Admin(config-probe-udp)# send-hex-data "abcd"
switch/Admin(config-probe-udp)# expect ?
hex-regex Configure Hex data expected as response
regex Configure probe expected response
switch/Admin(config-probe-udp)# expect
Note If send-hex-data is configured then expect hex-regex should be configured. Similarly, if send-data is
configured, expect regex should be configured.
Expect Hex Regex Enter the expected response data from the probe destination. The Hex data
entered must be of even numbers and must be a single string consisting of
alphanumeric within the range of 0-9,a-f or A-F, and a maximum of 255
characters.
