Decoding and Formatting Incorrectly Formatted IEs
If an IE does not contain the required number of mandatory fields, or is
incorrectly encoded so that the IE cannot be properly decoded, an error
message is displayed indicating the bad IE and decoding for the IE is
aborted. The IE is displayed in hexadecimal. The remainder of the
packet is formatted normally.
If an IE contains the required number of fields, but one of the field values
is invalid and cannot be decoded, the field name is displayed as usual in
the resultant trace display. However, the particular field value (only) will
be displayed in hexadecimal format. As long as the remaining field
values are valid, they will be decoded and formatted as usual.
