SW805
#1
Ok Im confused.

SWITCH Test #01: Layer 2 Technologies - Part 1
28. (QID:SW805) Which two conditions must be met to establish a Layer 2 EtherChannel? (Choose
two.)

LAN ports in the EtherChannel must be contiguous.
All ports in the EtherChannel must be on the same module.
SPAN must be disabled on the ports.
All ports in the EtherChannel must operate in half duplex.
The trunking protocol must be the same for all links in the EtherChannel.

Correct Answer: 
SPAN must be disabled on the ports.
The trunking protocol must be the same for all links in the EtherChannel.


But over here in the Cisco site it says:
Source Ports
A source port (also called a monitored port) is a switched or routed port that you monitor for network traffic analysis. In a local SPAN session or RSPAN source session, you can monitor source ports or VLANs for traffic in one or both directions. The switch supports any number of source ports (up to the maximum number of available ports on the switch) and any number of source VLANs (up to the maximum number of VLANs supported). However, the switch supports a maximum of two sessions (local or RSPAN) with source ports or VLANs. You cannot mix ports and VLANs in a single session.
A source port has these characteristics:
It can be monitored in multiple SPAN sessions.
Each source port can be configured with a direction (ingress, egress, or both) to monitor.
It can be any port type (for example, EtherChannel, Gigabit Ethernet, and so forth).
For EtherChannel sources, you can monitor traffic for the entire EtherChannel or individually on a physical port as it participates in the port channel.
It can be an access port, trunk port, routed port, or voice VLAN port.
It cannot be a destination port.
Source ports can be in the same or different VLANs.

You can monitor multiple source ports in a single session.

So then why is the right answer that span must be disabled? it didn't specify if its a source or destination...
