ACE software version A5(3.0) supports configuring of send-data and expect regex CLI commands to 
accommodate the configuration of Hex data. If Hex data configured is “ae5530”(6 bytes) then the 
converted value will be Hex ae,55,30 (3 bytes). 

The first two bytes of the Hex string are taken and converted to one byte actual Hex value (For example- 
‘a’ & ‘e’ from the string would be combined to form hex value ‘ae’). This conversion model is based on 
the existing hash value config under HTTP/HTTPS probe. The same CLI command modification can be 
covered under TCP and UDP probes.

The following new commands have been added to configure hex data and hex regex under TCP and UDP 
probes:

switch/Admin(config-probe-tcp)# ?

Configure tcp probe params:

connection     Configure probe connection parameters

description    Configure description string for probe

do             EXEC command

end            Exit from configure mode

exit           Exit from this submode

expect         Configure expected probe result code

faildetect     Configure parameters to detect probe failure on servers

interval       Configure interval between probes

ip             Configure probe IP parameters

no             Negate a command or set its defaults

open           Configure maximum time to wait for TCP connection to open

passdetect     Configure params needed to pass the servers in fail state

port           Configure port number for this probe

receive        Configure max time to wait inorder to receive reply from server

send-data      Configure data to be sent for probe

send-hex-data  Configure hex data to be sent for probe

switch/Admin(config-probe-tcp)# send-hex-data  

<WORD>  Enter the data in hex format to be sent as part of probe request (Max Size - 254)

You can use the keyword send-hex-data to configure the probe for allowing hex data.

switch/Admin(config-probe-tcp)# expect ? 

hex-regex Configure Hex data expected as response 

regex Configure probe expected   response

switch/Admin(config-probe-tcp)# expect hex-regex ? 

<WORD> Enter the expected response data in Hex format (Max Size - 254)

You can use the keyword hex-regex to configure the probe for allowing hex in expect regex CLI 
commands.

The following conditions should be taken care while configuring hex data:

Enter Hex data in an even numbered length and a maximum size of 254
