Good morning,
In reference to one incidence the list of bugs was analyzed that
it presents the platform of HW and the IOS in case it has some related to
problems of level 2, since think that the problem could come by
there.
Please, you can verify if bug in this IOS related is some to
port-mirrow or sessions SPAN?
The consultation must to that the incidence agreed with the configuration of
a SPAN session (origin one vlan completes, destiny an interface) and
during the tests we have made some other session similar and not always it has
worked correctly.
