hello all,
in my lab,i have a test as follows:
pc1-------2/1 switch-5k 2/2---pc2
pc1 is 192.1.1.1
pc2 is 192.1.1.2
when i input "set span 2/1 2/2 inpkts enable" into the switch-5k,pc2 can ping p
c1 successfully
when i input "set span 2/1 2/2 inpkts disable"into the switch-5k,pc2 can ping p
c1successfully too.
But according to cisco document,when use inpkts disable,switch-5k should not re
ceive packet from pc2.
Why pc2 can ping pc1 successfully when using "inpkts disable"?
And when i input "sh cam d',i can not see the MAC address for pc2 whether i use
"inpkts en" or "inpkts dis",why?
******************************
Use the inpkts keyword with the enable option to allow the SPAN destination por
t to receive normal incoming traffic in addition to the traffic mirrored from t
he SPAN source. Use the disable option to prevent the SPAN destination port fro
m receiving normal incoming traffic
******************************
would you please tell me reason about above?
