i would enable Span on my Switch. I use these Commands:
- monitor session 1 source GigabitEthetnet 0/1 both
- monitor session 1 destination GigabitEthernet 0/23
On Port GigabitEthernet 0/23 i have the Server which runs Ethereal. When I enter the second command the GigabitEthernet 0/23 is unavailable.
Whats the Mistake?
