Exam 300-115 topic 4 question 21 discussion

Yes, B D "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, and you cannot mix ports and VLANs in a single session. A source port has these characteristics: It can be monitored in multiple SPAN sessions. It can be any port type (for example, EtherChannel, Fast Ethernet, 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. A destination port has these characteristics: It can participate in only one SPAN session at a time (a destination port in one SPAN session cannot be a destination port for a second SPAN session). It does not participate in any of the Layer 2 protocols (STP, VTP, CDP, DTP, PagP)." https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-2_55_se/configuration/guide/scg_2960/swspan.html
