1) A policy that has been applied to a segment cannot be deleted. If you delete a policy on the
bandwidth management policy displaying page, you just delete the policy application.
2) The system-defined bandwidth management policy and rule cannot be deleted.
3) On a segment, one packet can match only one bandwidth management policy. If multiple
bandwidth management policies are applied to a segment, the system matches packets against
segment policies in the descending order of precision of IP address ranges specified in the policies;
for segment polices with the same IP address range precision, the policy configured first is
preferentially matched.
4) In the rule list of the bandwidth management policy, if the service referenced by a rule does not
exist, the service name of the rule is displayed as “! Unknown”.
5) To import a user-defined protocol file to the device successfully, you must write the user-defined
protocol file in a certain format, as shown in the following example:
Protocol_begin
Protocol_name=protocol
Protocol_description=the description of the protocol
Protocol_type=TCP
Protocol_status=enable
Protocol_port=457-666,45
Protocol_string=test protocol string
Protocol_regex=test protocol regex
Protocol_end
Table 18-8 Description on the parameters in a user-defined protocol file
Parameter Description Required/optional
Protocol_begin
Start line of the user-defined protocol.
Each user-defined protocol must begin with Protocol_begin.
Required
Protocol_name
Name of the user-defined protocol.
The parameter is a string of 1 to 255 characters, excluding the
space before or after the string. Required
Protocol_description
Description of the user-defined protocol.
The parameter is a string of 1 to 255 characters, excluding the
space before or after the string. Optional
Protocol_type
Type of the user-defined protocol.
This parameter can be TCP or UDP.
Required
Protocol_status
Status of the user-defined protocol.
This parameter can be enable or disable.
Required
Protocol_port
Port range of the user-defined protocol.
A port number ranges from 0 to 65535; use a hyphen (-) to
specify a port number range; you can specify up to eight port
ranges, which are separated by commas (,). For example,
“0,2,5,10,1021-30,8080,9000-9005,9010”.
Protocol_string
Signature string of the user-defined protocol.
The parameter is a string of 8 to 255 characters, excluding the
space before or after the string.
Use either approach
