Which statements are valid for a local SPAN configuration? (Choose two.)
A. Source and destination interface must be on the same host
B. Source and destination interfaces can be on different hosts
C. Destination vEthernet interface can be on a different VLAN than the source
D. Destination interface can be a physical port
E. Destination interface cannot be a physical port
Correct Answer: AD
Explanation/Reference:
Explanation:
Each local SPAN session must have at least one destination port (also called a monitoring port) that receives a copy of traffic from the source ports or VLANs. A destination port has these characteristics:
Can be any physical or virtual Ethernet port or a port channel.
Cannot be a source port.
Is excluded from the source list and is not monitored if it belongs to a source VLAN of any SPAN session.
Receive copies of transmitted and received traffic for all monitored source ports. If a destination port is oversubscribed, it can become congested. This congestion can affect traffic forwarding on one or more of the source ports.
Do not receive any forwarded traffic except copies of transmitted and received traffic for all monitored source ports.
Must be on the same host (linecard) as the source port.
In Local SPAN, the source interface and destination interface are on the same device.
