Hi Ron,
Thanks for your response. I was missing the 'git commit' step.
I've now managed to create the patch file and I have attached it to the
bug.
What happens next?
Cheers
AlanE

Alan,
Commit your patches to your local repo, then "git format-patch -M -C
remotes/origin/master" should give you a patch file.
Ron

Subject: Problem with Linkd and Cisco Router : No ipRouteTable in MIB
Hello List,
I am posting this to the devel list as suggested.
I fancy having a go at fixing this myself.
My first thought was to model the fix on the same way the VlanTable is
populated and change the OID based on the ClassName of the device.
The problem with this approach is that different Cisco IOS loads will
use different OIDs so there is no 1 correct OID that will work for all
Cisco routers.
Either I need to have a new configuration parameter to tell me which OID
to use to get the routing info or I need to check the IOS version and
have some sort of lookup table to try to figure it out.
Any suggestions would be appreciated.
Thanks
AlanE
------------------------------------------------
I was wondering if anyone else has come across this problem and if there
was a known solution.
According to the Linkd wiki http://www.opennms.org/wiki/Linkd one of the
first things Linkd does is walk the ipRouteTable.
However I have a Cisco Router (7604) which doesn't have an ipRouteTable.
Apparently this has been removed by Cisco and I am now supposed to use
the ipCidrRouteTable in the IP-FORWARD-MIB.
In fact even has been deprecated in the latest Cisco IOS and we should
now use inetCidrRouteTable.
If I try snmpwalk. I can confirm that on my router ipRouteTable doesn't
work but the ipCidrRouteTable does work.
[r...@nms daemon]# snmpwalk -t5 -r5 -v2c -c public ks1-trial-lbr
.1.3.6.1.2.1.4.21
RFC1213-MIB::ipRouteTable = No Such Object available on this agent at
this OID
[r...@nms daemon]#
[r...@nms daemon]# snmpwalk -t5 -r5 -v2c -c public ks1-trial-lbr
IP-FORWARD-MIB::ipCidrRouteTable
IP-FORWARD-MIB::ipCidrRouteDest.0.0.0.0.0.0.0.0.0.10.101.24.9 =
IpAddress: 0.0.0.0
IP-FORWARD-MIB::ipCidrRouteDest.10.101.24.0.255.255.255.0.0.0.0.0.0 =
IpAddress: 10.101.24.0
IP-FORWARD-MIB::ipCidrRouteDest.10.101.24.4.255.255.255.255.0.0.0.0.0 =
IpAddress: 10.101.24.4
IP-FORWARD-MIB::ipCidrRouteDest.10.101.30.0.255.255.255.0.0.0.0.0.0 =
IpAddress: 10.101.30.0
<snip>
The problem I have is that the "Physical Interface" tab on the node view
is blank and the "Node Links" table has no information.
I have another router with an older IOS running and this works just
fine. I can walk the ipRouteTable and the "Physical Interfaces" display
correctly.
I am using opennms version: 1.7.10
Any suggestions would be appreciated.
Thanks
AlanE

ipRouteTable in MIB
So I took a look at the source code and it appears that I am out of
luck.
I can see in
opennms/opennms-services/src/main/java/org/opennms/netmgt/linkd/snmp/IpR
outeTableEntry.java
The ipRouteTable OID is hardcoded and there doesn't appear to be any
other options available.
I've searched bugzilla and there doesn't seem to be a bug report for
this issue which seems a bit odd, I'm sure I'm not the only one managing
Cisco Routers that have no ipRouteTable.
Anyway, I will raise a bug report as soon as I receive my randomly
assigned password to login to bugzilla.
Cheers
AlanE
