And..... since the vendor and agent
fields are not updated after discovery, you should delete and rediscover
the node after setting up the oid_to_type entry.

Usman,
I'll answer this one and give
James a break.
NetView requires an exact match
for the OID of a device, otherwise, in the Windows version, it is assigned
to the BadOID smartest.
If NetView can determine via
SNMP, that IPforwarding is turned on, it will draw a router symbol
(diamond with 4 headed arrow), regardless if the OID matches a pre-defined
record in oid_to_sym or not. 
 
To get your Cisco3745 out of
thr BadOID smartest add a record containing the exact OID of the device
to oid_to_sym.
Adding it to oid_to_type is
optional, since NetView already knows it is a router via SNMP, but do it
anyway.
 
HTH,
Don Davis.

James, 

You see, the NetView recongnizes the devices and also shows the appropriate
symbol for e.g we have Cisco3745 Router and the symbol it shows is for
a Router, but again it puts it in the BadOIDs smartset??? Why is it so
when it is detecting the device with respect to its behaviour and then
again puts it in the BadOID smartset, i am a bit confused??

oid_to_type, and it's sister, oid_to_symbol,  let NetView know what
kind of
a device it is dealing with.  If you actually go look at these files
it
will be obvious how they are used, because there extensive comments in
the
front of the files which explain the parameters in them.  There are
OIDs
from many vendors and their various boxes.  But there will always
be some
that are not there.

That's where the BadOID smartset comes in.  On Windows, any device
whose
OID is not in the oid_to_type gets put in this smartset by default, in
order to let you know that NetView does not know what kind of a device
(router/gateway, switch, bridge, etc) it is.

If your devices return an OID which is not in oid_to_type, then NetView
will just treat them as a simple workstation, and by oid_to_symbol, it
will
represent them as generic boxes on the map.   If that is appropriate,
or
you don't care, then you need do nothing with these files.    
If however,
you have something which needs special handling or deserves a better
symbol, then you need to update those files accordingly.

All this is explaining in the NetView for Windows books that ship with
the
product.

Farrag,

But why do i need to do that, i havent made any changes, i did a clean
installation and it puts the devices in that SmartSet. Why do i need to
change the oid_to_Type file.?

Hi,

Read about editing the oid_to_type file in the Netview Unix administrator's
guide page 177.
To know the OID of a bad OID device querey the SNMP system variables
snmpwalk -c community_name hostname system

to reflect the changes you made to the oid_to_type you should do the
following:
- restart the netmon daemon.
- issue a demand poll over the devices with bad OIDs.

Best regards,

Alaa Farrag
