ipv6 traffic graph

Hi,

how do you graph your ipv6 traffic on a cisco router if you have an interface that route v4 and v6 mixed traffic?

Does exist a MIB to do this or whatever else?

Thanks!

Matteo

Re: ipv6 traffic graph [In reply to]

I've been screen scraping "show interfaces accounting" and taking the
data from the IPv6 row and shoving it into RRD. Be aware of the
following however:

The Pkts Out and Chars Out fields display IPv6 packet counts only. The
Pkts In and Chars In fields display both IPv4 and IPv6 packet counts,
except for tunnel interfaces. For tunnel interfaces, the IPv6 input
packets are counted as IPv6 packets only.

Due to hardware limitations on the ASIC, PFC IPv4 and IPv6 packets
cannot be differentiated in the Pkts In and Chars In fields for IP
count the IPv6 and IPv4 packets that are hardware forwarded. The Pkts
In and Chars In fields for IPv6 only count software-forwarded packets.
The IP Pkts Out and Chars Out fields show IPv4 packets, and the IPv6
Pkts Out and Chars Out fields show IPv6 packets.

Hope that helps a bit.

That's for 6500/7600 with Sup720. Other platforms do not have this
particular weirdness.

Re: ipv6 traffic graph [In reply to]

I opened a TAC to Cisco and finally they told me these OID:

ipIfStatsTable
http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.4.31.3#oidContent

ipIfStatsEntry
http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.4.31.3.1#oidContent

but are only supported on > 15.1(3)T

can someone try them and tell me if these are running or not. I don't have any routers with that IOS version.

I understood that the Cisco engineers (and IOS developers) are a bit not sure about this... and I'm not trust very well on this feedback...

Hi David,

it depends on your SNMP security schema, but if you have a simple read community you can use these commands:

snmpwalk -c $YOURCOMMUNITY -v2c $IP 1.3.6.1.2.1.4.31.3
snmpwalk -c $YOURCOMMUNITY -v2c $IP 1.3.6.1.2.1.4.31.3.1

Thanks

Matteo

Hi Klaus, wonderful!

So definitively with this new MIB you can make two different IPv4/IPv6 graphs using these OIDs:

For IPv4 only
> IP-MIB::ipIfStatsHCInOctets.ipv4.17 = Counter64: 776641981
> IP-MIB::ipIfStatsHCOutOctets.ipv4.17 = Counter64: 1109298546

For IPv6 only
> IP-MIB::ipIfStatsHCInOctets.ipv6.17 = Counter64: 1583364
> IP-MIB::ipIfStatsHCOutOctets.ipv6.17 = Counter64: 877639

Obviously I immagine that 17 is the ifIndex.

Very very nice.

I will tell thank also the Cisco support, they did a great job, we worked almost 15 days on this ticket and were involved also IOS developers to get a serious answer;)

Thanks,

Matteo
