I see the twice counted outbound traffic on subinterfaces that has ISL encapsulation on my SUP720-3BXL with s72033-advipservicesk9_wan-mz.122-33.SXJ1.bin. I haven't seen this problem with s72033-advipservicesk9_wan-mz.122-18.SXF17.bin
Don't hit me for ISL, it is worked by historical reasons. I have already change ISL to 802.1q - and it seems look like a workaround. I can't find this problem in Bug Search Tool, so if you can please drop me a bug id.
It is very simple. I have tool, named Cricket, that based on RRD Tool and collect every 5 minutes SNMP-data from my network devices. So this tool collects ifHCInOctets and ifHCOutOctets and make picture from collected data. After I have changed IOS from s72033-advipservicesk9_wan-mz.122-18.SXF17.bin to s72033-advipservicesk9_wan-mz.122-33.SXJ1.bin I have seen that graphics that based on ifHCOutOctets on all of my ISL encapsulated interfaces on SUP720 and X6748-SFP cards have been counted twice.
Another conformation of the twice counted traffic in SNMP-data that all traffic that passed trouth ISL subinterface and than passed trourh 3750 not counted twice on 3750 interface.
And another one conformation is that after I have changed encapsulation type from ISL to 802.1q - all SNMP counters become right.
About 2 hours ago I have tested the same IOS version on SUP32-GE-3B, and have seen the same problem with ifHCOutOctets counter on ISL subinterfaces. I have changed ISL to 802.1q and counter become right.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
