Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally:
monitor session 2 filter vlan 1 8, 39, 52
What is the result of the implemented command?
A.
All VLAN traffic is sent to the SPAN destination interface.
B.
Traffic from VLAN 4 is not sent to the SPAN destination interface.
C.
Filtering a trunked SPAN port effectively disables SPAN operations for all VLANs.
D.
The trunk’s native VLAN must be changed to something other than VLAN 1.
E.
Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.
Explanation:
The “monitor session filter” command is used to specify which VLANS are to be port mirrored using SPAN. This example shows how to monitor VLANs 1 through 5
and VLAN 9 when the SPAN source is a trunk interface:
Switch(config)# monitor session 2 filter vlan 1 5 , 9
