If the window goes away, do you get a core file?  Look in the directory you
were in when you started the V1/V2 browser or the $HOME directory of the
user who is ruuning it.  If you find one, call Support.

Subject:  [NV-L] Re: SNMPv1/SNMPv2






Ok, I think I get it.
Well the problem with the PIX is the following;

Just about any device on the net is browsable (say get mib-2 sysDescr or
ifTable) with either SNMP or SNMPv1/SNMPv2 and they behave normal to SNMP
queries, show up normal in map, is possible to
make "Monitor -> Network Configuration -> Addresses" and so on. But, the
PIX shows up in the map with
a generic icon showing only one interface, out of four. When I do "Monitor
-> Network Configuration -> Addresses", I get the answer "ERROR getting
table from xxxxxx: The variable does not exist or is read only". With the
MIB Browser I can get for example the mib-2 ifTable mib from SNMP but when
I try from SNMPv1/SNMPv2 the windows just dissapears about two seconds
after I hit the Start Query button. This is the case with just about any
query under SNMPv1/SNMPv2.
So, NetView doesn't understand that this device has more than one
interface, opening it up shiws only one interface, SNMPV1/SNMPv2 browsing
doesn't work, the Monitor -> Network Configuration menues doesn't work, but
doing SNMP mib browsing works and is the only way to get SNMP values at all
from it. I can't figure this out.

I'm running NetView 6.0.1 on Solaris 2.6.

NetView is provided with two separate MIB Browsers. The "MIB Browser ->
SNMP....." option browses the snmpmib.bin file (SNMPv1 MIBs only). The "MIB
Browser -> SNMPv1/SNMPv2..." option browses a completely separate MIB tree,
the snmpv2mib.bin file which supports both SNMPv1 and SNMPv2 MIBs.
Consequently there are two separate MIB Loaders, each pointing to the
appropriate MIB tree, snmpmib or snmpv2mib.

You can choose to load both SNMPv1 and v2 MIBs into snmpv2mib tree with the
SNMPv2 Loader and thus browse these MIBs with the SNMPv1/SNMPv2 Browser.
However, with the exception of loading and browsing of these MIBs, NetView
doesn't use this MIB tree for anything else. For example, snmpCollect uses
the SNMPv1 MIBs loaded in the snmpmib.bin file. snmpCollect does not look
at the snmpv2mib.bin file and so will not see either the SNMPv1 or SNMPv2
MIBs loaded in this tree. Others like netmon and trapd would also only use
SNMPv1 loaded MIBs (in the snmpmib.bin file). There may be exceptions to
this rule and you would need to check with Tivoli Support to see if any of
these exceptions were supported.

As for your problem using the the SNMPv1/SNMPv2 browser with your PIX
firewall device -  What MIB are you trying to browse?  Is it a v1 or v2 MIB
?  At what point is the browser dying ?  What do you mean by "dies" ?  What
version of NetView are you using and what OS ? Have you tried to browse
other MIB variables ? Have you tried the v1/v2 Browser with other devices
who's agent you know support the MIB variable you are requesting info on ?
