Parameter Description
Firewall
configure network > access-list
[AccessList]
The table defines the device's access list (firewall), which defines
network traffic filtering rules.
The format of the ini file table parameter is:
[AccessList]
FORMAT AccessList_Index = AccessList_Source_IP,
AccessList_Source_Port, AccessList_PrefixLen,
AccessList_Source_Port, AccessList_Start_Port,
AccessList_End_Port, AccessList_Protocol,
AccessList_Use_Specific_Interface, AccessList_Interface_ID,
AccessList_Packet_Size, AccessList_Byte_Rate,
AccessList_Byte_Burst, AccessList_Allow_Type;
[\AccessList]
For example:
AccessList 10 = mgmt.customer.com, , , 32, 0, 80, tcp, 1, OAMP,
0, 0, 0, allow;
AccessList 22 = 10.4.0.0, , , 16, 4000, 9000, any, 0, , 0, 0, 0, block;
In the example above, Rule #10 allows traffic from the host
‘mgmt.customer.com’ destined to TCP ports 0 to 80 on interface
OAMP (OAMP). Rule #22 blocks traffic from the subnet
10.4.xxx.yyy destined to ports 4000 to 9000.

Media Latching
Inbound Media Latch Mode
configure voip > media settings
> inbound-media-latch-mode
[InboundMediaLatchMode]
Enables the Media Latching feature.
[0] Strict = Device latches onto the first original stream (IP
address:port). It does not latch onto any other stream during the
session.
[1] Dynamic = (Default) Device latches onto the first stream. If it
receives at least a minimum number of consecutive packets
(configured by New<media type>StreamPackets) from a
different source(s) and the device has not received packets
from the current stream for a user-defined period
(TimeoutToRelatch<media type>Msec), it latches onto the next
packet received from any other stream. If other packets of a
different media type are received from the new stream, based
on IP address and SSRC for RTCP/RTP and based on IP
address only for T.38, the packet is accepted immediately.
Note: If a packet from the original (first latched onto) IP
address:port is received at any time, the device latches onto
this stream.
[2] Dynamic-Strict = Device latches onto the first stream. If it
receives at least a minimum number of consecutive packets
(configured by New<media type>StreamPackets) all from the
same source which is different to the first stream and the device
has not received packets from the current stream for a user-
defined period (TimeoutToRelatch<media type>Msec), it
latches onto the next packet received from any other stream. If
other packets of different media type are received from the new
stream based on IP address and SSRC for RTCP and based on
IP address only for T.38, the packet is accepted immediately.
Note: If a packet from the original (first latched onto) IP
address:port is received at any time, the device latches onto
