Possible Reasons
Actions
Inventory: device
serial or router
chassis numbers
differ from those
shown on outside
labels.
Hardware reports
get data from the
user-defined
optional serial
number field when
the device or
router is added to
the Essentials (or
via Change Device
Attributes), not
from the SNMP
variable chassis
serial number. The
manually changed
serial number
takes precedence
over the external
number.
No action is required, although you can
manually change the serial number back to
match the external number.
Inventory: device
stays in a pending
state.
The database is
corrupt.
Stop Essentials. Install a backup database,
if available; otherwise, install the basic
database,
px.db,
over the corrupt database.
DIServer is not
running.
Check the process status. If DIServer is not
running, restart it.
A broadcast
address has been
imported and is
being used for an
SNMP write.
Suspend the device. Run the address
validation tool on the device (Tools;
Connectivity Tools; Validate Device
Addresses) to ensure that a broadcast or
network address is not being used.
Inventory: devices
not importing.
An access list has
been applied to the
SNMP-server
community
configuration.
Add
permit
statements to the access lists
on all routers.

has occurred.
Increase SNMP slow timeout and retry
values.
