3.2(2) 3.3(0) 3.3(1)

Description (partial)

Symptom:

Upon importing the config from FWSM, if the maximum packet length for dns
inspection was not specified, CSM would try to push value 0 (inspect dns
maximum-length 0) even thought the default value is 512. This will result in a
failed deployment as value 0 is not supported by FWSM.

Conditions:

Not specifying maximum packet length for dns inspection.
Example:

policy-map global_policy
 class inspection_default
  inspect dns
