Re: [nv-l] mibtable hangs for ospf table on cisco

[Leslie Clark <lclark@us.ibm.com>]

The mibtable command had trouble with
tables where not all values are populated for all rows. I know there was
an apar for that problem but I am not sure which level of code the fix
was included in. Usually the problem was that it shifted values around
to fill in the holes. Try making a mib application to do the same thing
as that script (I made that from a mib application so I could run it at
the commandline). If it does not work right for you there, call support
for assistance. 
The mib application builder is under
the Tools menu. It's output goes in /usr/OV/registration/C/ovmib, and the
resulting application can be found on the menu under Monitor..

Subject	[nv-l] mibtable hangs for ospf table on cisco

By trying Leslie's script get_ospf_if_sh, I discovered that the script
hangs
on all my cisco routers. By trying the mibtable , I discover that it hangs
after a few "dummy" ospf entries:


# /usr/OV/bin/mibtable -table ".1.3.6.1.2.1.14.7.1" \
      -fields "ospfIfIpAddress=1:15,ospfIfAreaId=3:15,ospfIfAdminStat=5:8"
-node router1

                    
 User Specified MIB Table for router1

ospfIfIpAddress  ospfIfAreaId     ospfIfAdminStat
0.0.0.0          0.0.0.0      
   disabled
0.0.0.0          0.0.0.0      
   disabled
0.0.0.0          0.0.0.0      
   disabled




and then mibtable hangs.

If I do a snmpwalk on the node, it works OK:

# snmpwalk router1 .1.3.6.1.2.1.14.7.1

ospf.ospfIfTable.ospfIfEntry.ospfIfIpAddress.10.224.142.1.0 : IpAddress:

.............


The number of those "dummy" instances in the mib varies from
router to
router, but there is
at least one. For example:

# /usr/OV/bin/mibtable -table ".1.3.6.1.2.1.14.7.1" \
         -fields
"ospfIfIpAddress=1:15,ospfIfAreaId=3:15,ospfIfAdminStat=5:8"
-node router2

                    
 User Specified MIB Table for router2

ospfIfIpAddress  ospfIfAreaId     ospfIfAdminStat
0.0.0.0          0.0.0.0      
   disabled

then hangs...

Any ideas?
Thanks.
