Unsupported Functionality

A manually set IDP Series device system clock setting is not preserved after upgrading to 5.1r1.
Workaround: Use NTP to set the IDP Series device system clock. If you do not want to use NTP, you can use
ACM to reset the system clock after you have completed the upgrade.

When you encounter a hung system, you might want to force a core dump. To do this, you type a
combination
IDP600, or IDP200.

Cosmetic issue: when no installed I/O module supports bypass, the ACM Configure Virtual Routers page should
not display the user interface group for NIC State. When no installed I/O module supports bypass, NIC state is
non-configurable.

ACM does not reject poorly formed alias names. In particular, ACM does not reject constructions with incomplete
double-quote strings. For example, "hello (missing end-quote). As a result, the alias name does not appear in
NSM.
To avoid this issue, be careful to use complete double-quote constructions for alias names. For example, "hello".
Detection Accuracy
279408
UDP port scanning works if there is no response from the Victim PC. However, if the response comes in the form
of "UDP Port not reachable," the detection ignores the flow because the response packet is more than 20 bytes
(default value).
To work around this issue:
1.
In the NSM Device Manager, double-click the name of the device to display the configuration editor.
2. Click Sensor Settings.
3. Click the Run-time parameters tab.
4. Under Traffic Signatures, increase the value for Byte threshold for suspicious flows.
