Mark,
Thank you for your advice.
I have tried the snmpwalk command with -d option and found
that the failure one was using the community string index! e.g. the good
one using the string "private" and the failure one using the string "private@10". I didn't specify with the -c
option.
Both switches configured VLAN1, VLAN10 and VLAN300. The
good one was using VLAN1 IP address and the failure one was using VLAN10 IP
address (different subnets). I have changed now the failure one with the VLAN1
IP address (same subnet as the good ones). Then the -d option showed the
community string is right ("private"). Up to now (two hours past), Netview has
not discovered it (my Netview machine was low configured (cpu and mem) with
quite big database). Let me verify tomorrow.
Another difference was the good one has configured a
virtual loopback interface (without IP address assigned) and the failure one
not. I added a virtual loopback interface to the failure one too to make them
"identical".
Regards,
David
Hi David,
Are both machines defined correctly in "xnmsnmpconf",
specifically the community string?
Did you try a "mib browser" of failing device to make sure NetView is
using correct community name? Select the working device, browser it,
then enter the address or name of other device and attempt to browser same
mib, does the browser show the correct community name being used?
Also, did you check the 3550 to ensure
that NetView machine is allowed to query snmp on it? It is a problem I
have run into here in the lab with newly deployed devices. My network tech, is
telling me that I have to provide a name/address of all machines I want to
access the Cisco device, and since I am in a test lab, the number of machines
that need access to Cisco devices, gets fairly long.
Did you provide community string with the snmpwalk
command, or let command get it from NetView?
Try the snmpwalk command with a -d option and no community string, to
see if command gets the correct community string from NetView.
"snmpwalk -d [3550name]
system" -- check output for correct community string being used.

Problems |

Dear list,
Need your advise and experience on the
following problem.
NV714, FP3, Solaris trying to discover Cisco 3550
switch with routing
function (several VLAN configured and using community
string index).
The strange thing is that two switches with the same
configuration, one
can be discovered and the other not (even I loadhosts it
manually, then
demandpoll doesn't work, in the NON-snmp smartset). They are
in the same
subnet too (they are in the same room). Command line snmpwalk
worked
fine for both.
Can you help? Thank you in
advance.
Regards,
David
