Hello group,
I am using snmprealwalk() to scan for interface types and descriptions on
some Cisco routers. What I am doing is two calls to walk the routers; one
walk for ifDescr.x and the other for locIfDescr.x so that I get the
interface index and our user defined descriptions.
That returns back two arrays which I then combine into one array with a
couple for and while loops, and that gives me a multidimentional array
containing the interface index, interface type, and the description. Things
have been going well, however, I have noticed that some of the newer routers
are not behaving as expected on some of the walks that I am doing.
When I do the two walks as described above, I get something like this:
Array (
[OLD-CISCO-INTERFACES-MIB::locIfDescr.1] => "Local LAN"
[OLD-CISCO-INTERFACES-MIB::locIfDescr.2] => ""
[OLD-CISCO-INTERFACES-MIB::locIfDescr.3] => ""
[OLD-CISCO-INTERFACES-MIB::locIfDescr.6] => "Internal Modem WIC"
[OLD-CISCO-INTERFACES-MIB::locIfDescr.7] => ""
<snip>
)
Notice how it is missing interface descriptions for interface index 4 and 5.
So I manually ran snmpget and I get the snmp error "No Such Instance
currently exists at this OID". The problem is that snmprealwalk() doesn't
fill the array when I get the "No such instance" message - which really
screws up my program.
Is there a way to make snmprealwalk() fill in values in arrays, even if
there is no valid snmp data?
Thanks in advance,
AJ Schroeder
