I am attempting to apply a display filter based on the ISAKMP Intiator SPI, which is f64e30753a4a41b6.

I have used the filter builder (expression) and as soon as I paste in either f6 4e 30 75 3a 4a 41 b6 or f64e30753a4a41b6 then the filter is shown as being invalid.

I have tried "f64e30753a4a41b6" and "f6 4e 30 75 3a 4a 41 b6" which works for the filter checker, but does not output any data even though I can see packets with ISAMP SPI set to f64e30753a4a41b6.

Any ideas?
