Version 6.2 97 February 2011
SIP User's Manual 3. Web-Based Management
Parameter Description
(network mask of 255.0.0.0).
A value of 16 corresponds to IPv4 subnet class B
(network mask of 255.255.0.0).
A value of 24 corresponds to IPv4 subnet class C
(network mask of 255.255.255.0).
The IP address of the sender of the incoming packet is
trimmed in accordance with the prefix length (in bits) and
then compared to the parameter ‘Source IP’.
Local Port Range
[AccessList_Start_Port]
[AccessList_End_Port]
The destination UDP/TCP ports (on this device) to which
packets are sent.
The valid range is 0 to 65535.
Note: When the protocol type isn't TCP or UDP, the entire
range must be provided.
Protocol
[AccessList_Protocol]
The protocol type (e.g., UDP, TCP, ICMP, ESP or 'Any'), or
the IANA protocol number (in the range of 0 (Any) to 255).
Note: This field also accepts the abbreviated strings 'SIP'
and 'HTTP'. Specifying these strings implies selection of the
TCP or UDP protocols, and the appropriate port numbers as
defined on the device.
Use Specific Interface
[AccessList_Use_Specific_Interface]
Determines whether you want to apply the rule to a specific
network interface defined in the Multiple Interface table (i.e.,
packets received from that defined in the Source IP field
and received on this network interface):
[0] Disable (default)
[1] Enable
Notes:
If enabled, then in the 'Interface Name' field (described
below), select the interface to which the rule is applied.
If disabled, then the rule applies to all interfaces.
Interface Name
[AccessList_Interface_ID]
The network interface to which you want to apply the rule.
This is applicable if you enabled the 'Use Specific Interface'
field. The list displays interface names as defined in the
Multiple Interface table (see ''Configuring IP Interface
Settings'' on page 83).
Packet Size
[AccessList_Packet_Size]
Maximum allowed packet size.
The valid range is 0 to 65535.
Note: When filtering fragmented IP packets, this field
relates to the overall (re-assembled) packet size, and not to
the size of each fragment.
Byte Rate
[AccessList_Byte_Rate]
Expected traffic rate (bytes per second). This field defines
the allowed bandwidth for the specified protocol. In addition
to this field, the 'Burst Bytes' field provides additional
allowance such that momentary bursts of data may utilize
more than the defined byte rate, without being interrupted.
For example, if 'Byte Rate' is set to 40000 and 'Burst Bytes'
to 50000, then this implies the following: the allowed
bandwidth is 40000 bytes/sec with extra allowance of 50000
bytes; if, for example, the actual traffic rate is 45000
