Hi All,
I am having some trouble in getting my Learn Lists to match traffic in PfR.
With reference to this Cisco document:
http://www.cisco.com/en/US/docs/ios/oer/configuration/guide/pfr-profile.html#wp1062974
However, my Learn-Lists never show any stats other than 0, even though
the traffic is passing through the outside interface.
In brief, R6 is acting as the MC/BR and R4 is a BR with 2 outside
interfaces - these routers are in AS100.
R4 connects to R5 via a serial interface (S0/2/0), and R5 directly
connects to SW2.
R5 and SW2 are in AS200.
A quick traceroute from R1 (also in AS100) to SW2 confirms the route
taken is R4>R5>SW2.
Rack1R1#traceroute 150.1.8.8 source lo0
1 155.1.146.4 4 msec 4 msec 0 msec
2 155.1.45.5 12 msec 8 msec 8 msec
3 155.1.58.8 12 msec * 8 msec
To provide suitable traffic I start a telnet session from R1 to SW2 and
run a "show tech":
Rack1R1#telnet 150.1.8.8 /source-interface loopback 0
The MC records the prefix o.k.:
Rack1R6#show oer master prefix
OER Prefix Statistics:
Pas - Passive, Act - Active, S - Short term, L - Long term, Dly - Delay
(ms),
P - Percentage below threshold, Jit - Jitter (ms),
MOS - Mean Opinion Score
Los - Packet Loss (packets-per-million), Un - Unreachable
(flows-per-million),
E - Egress, I - Ingress, Bw - Bandwidth (kbps), N - Not applicable
U - unknown, * - uncontrolled, + - control more specific, @ - active
probe all
# - Prefix monitor mode is Special, & - Blackholed Prefix
% - Force Next-Hop, ^ - Prefix is denied

But it does not capture the telnet traffic:

Note that I have also tried it with HTTP traffic:
Rack1R1#copy
http://cisco:cisco@150.1.8.8/c3560-ipservicesk9-mz.122-53.SE1.bin null:
... with the same effect, i.e. no Traffic-Class Count hits.
As I am also running IOS 12.4(24)T2 on both OER routers I have also
tried matching application name using nbar with no success.
So any ideas what I am missing? Is it reasonable for me to assume that
the count will increase?
