On CISCO-ACL-MIB.my I found: caAclLabelIntfStatsEntry.2 = caAclIntfStatsPackets ("The total number of packets that match this counter label.") caAclLabelIntfStatsEntry.3 = caAclIntfStatsOctets ("The total number of octets that match this counter label.") There is also: caAclLabelIntfStatsEntry.1 = caAclIntfStatsCounterLabelName ("The counter label index associated with this set of statistics.") ...but it seems IOS XR doesn't support it, at least on v5.3.4.
So, I had 20617 packets and 1803947 bytes matching my counter.
Then, after several tests and many counters configured I figured out what the last numbers on the OID chain meant.
In the example: caAclIntfStatsOctets.126.96.36.199.188.8.131.52
interface index that you get when do snmpwalk with oid .184.108.40.206.220.127.116.11.1.1.
I don't know, it's was the same number for all the tests.
ACL direction (1 for in and 2 for out).
Length of the name of the counter ("test" in my example).
.'t'.'e'.'s'.'t' in ascii code
Once I knew this information I did a template for Cacti to graph the bytes matched for each counter. In this manner, having entries of this type:
permit ipv4 any x.x.x.0 0.0.0.255 counter network_A
...you can have graphs of bandwith usage per link for network_A, or maybe:
permit tcp any any eq www counter HTTP
... for bandwith usage by protocol (HTTP). Of course, notice that one packet can only match one entry, so it's not a good idea to use both examples of above in the same ACL.
Of course, you could also do all this using netflow but you'll need a software to process the data.
