Monitoring IPv6 interface counters

[jschmied]

I have been asked to use Cacti to graph IPv6 counters on our AS9K interfaces running XR 5.1.3.

Is there a corresponding SNMP OID for the IPV6_UNICAST counter shown here or from the "show monitor" commands?

I found these in some other posts but no success yet:

1.3.6.1.2.1.4.31.3.1.6

1.3.6.1.2.1.4.32.3.1.33

Thanks!

Jamie,

nms-server2:~ % snmpwalk -v 2c -c public 172.18.87.48 1.3.6.1.2.1.4.31.3.1

Thanks very much for the response. To take this another step further, I do receive similar results.

$ snmpwalk -v 2c -c public 192.168.1.1 1.3.6.1.2.1.4.31.3.1.6
IP-MIB::ipIfStatsHCInOctets.ipv6.5 = Counter64: 5507656796
IP-MIB::ipIfStatsHCInOctets.ipv6.53 = Counter64: 2889781036972
IP-MIB::ipIfStatsHCInOctets.ipv6.68 = Counter64: 33395567336320

However, I get this when I try to poll one of the specific instances/interfaces so I can graph the specific counter;

$ snmpwalk -v 2c -c public 192.168.1.1 1.3.6.1.2.1.4.31.3.1.6.68

IP-MIB::ipIfStatsHCInOctets.ipv6.5 = Counter64: 5507660887
Error: OID not increasing: IP-MIB::ipIfStatsHCInOctets.68
 >= IP-MIB::ipIfStatsHCInOctets.ipv6.5

Is that not the correct OID for the specific interface counter?

Thanks again!

Jamie

This worked for me. 68 is the interface ifindex.

$ snmpwalk -v 2c -c public 192.168.1.1 1.3.6.1.2.1.4.31.3.1.6.ipv6.68
IP-MIB::ipIfStatsHCInOctets.ipv6.68 = Counter64: 33411092662585

$ snmpwalk -v 2c -c public 192.168.1.1 1.3.6.1.2.1.4.31.3.1.5.ipv6.68
IP-MIB::ipIfStatsInOctets.ipv6.68 = Counter32: 767076210

The Cacti graphs are working.

Thanks again!

Hi am doing the same but cacti is nor graphing. Did you try by index query?

Your reply will be helpful.

Thanks

This is the cheat sheet I use to create the Cacti IPv6 graphs. Please try this and let me know if you have any problems. Good Luck!!

Your procedure worked great. Thanks for the information. I wonder why my xml file for index query doesn't work . As per your procedure I can graph for each specific interface. But with my xml file if I did index query i was expecting to graph whatever interface i select but its not. Still am not getting that point. have you experienced the same?

[jschmied]

I also tried xml but could not get it to work. I am not an xml expert. I'm not sure if it was a problem with xml or just my lack of knowledge to build it correctly. Glad the cheat sheet worked for you!

[Pradeep.AnandhSelvaraj1]

Yes your cheat code saved my life. Thanks a lot

[Pradeep.AnandhSelvaraj1]

Jamie/Jschmied,

The cheat code you have suggested cannot be implemented globally rite? what am trying is creating a template for ipv6 graph. Using snmp index query if we use that template to whatever interface we select it should start graphing. As per your cheat code I can graph it by entering oid of each interface manually. The reason I keep focusing on snmp index query is we have hundreds of interfaces where IPV6 traffic pass through. Creating datasource for inbound/outbound traffic of each interface seems consumption of load and time in my case. Do you have any idea for that?

Thanks

Pradeep

[jschmied]

You are correct. The process is manual and would not be efficient if you have a great number of interfaces to graph. In my case, we were only interested in graphing IPv6 traffic at our up and downstream interfaces which added up to 20-25 interfaces total. Unfortunately, I do not have insight into programming Cacti to accomplish this feat. I would be interested in knowing how to do it too.

[Pradeep.AnandhSelvaraj1]

Jamie,

I finally found how to make query. Before that i need to see your xml file for graphing ipv6 counter.Or you can tell what oid you have configured in xml

[jschmied]

Pradeep,

That is great news! This is the XML. I tried several variations of the OID. It did not work but maybe you can tell me what I did wrong.

Use below code and let me know what happens

                        <name>Bytes In - 64-bit Counters IPV6</name>
                        <method>walk</method>

                </ipIfStatsHCInOctets>

                <ipIfStatsHCOutOctets>
                        <name>Bytes Out - 64-bit Counters IPV6</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>output</direction>
                        <oid>IP-MIB::ipIfStatsHCOutOctets.ipv6</oid>

Jamie: "The template "SNMP-IPv6 Traffic Graph Template" was created?, but i don´t found the template in the Cacti.

Thanks,
