Hi
I have a question about monitoring ports (monitor session). I'm doing the
SPAN section where you have routers 1 and 2 connecting to switch 1 on port
f0/1 and f0/2 respectively. Then R6 connects to f0/6. The monitor session is
set up to with the source being VLAN12 which both R1 and R2 are part of. The
destination is F0/6 on SW (R6).
To verify we enable debugging on R6. Then we ping 255.255.255.255 from R1
and see traffic on R6. No problem there.
The question I have is, why don't you see traffic on R6 when you ping to
R2's IP from R1? Surely R6 should see that traffic as well?
Thanks, EP
