Tailf:alt-name "aes 128" add '\' to the inputs CLI

Hi All,

The CLI “rekey algorithm aes\ 128” works but “rekey algorithm aes 128” doesn’t work.
The same behavior is seen for ‘aes 128’, ‘aes 192’, ‘aes 256’ which has a white space in the string. The show run O/P displays without ‘\’ in the display.

How do I correct the below behavior so that the input also works for “rekey algorithm aes 128” also. The IOS parser accepts only “rekey algorithm aes 128” as input, what change shld i do that “rekey algorithm aes 128” is accepted in confd input also. As i need to have the same CLI work on both confd & IOS parser. Kindly let me your feedback

Regards,
Karthik. R
