Usage guidelines
You can repeat this command to configure multiple signatures of different match patterns in a
user-defined NBAR rule, and all signatures take effect. The logical relation of these signatures is OR,
which indicates that a packet that matches any signature matches the NBAR rule.
Examples
# Configure user-defined NBAR rule abcd to match packets with signature 1 which defines match
string abcdegf.
