Hello everybody, this is my first message. :) I'd like to clarify something that is confusing me for a while.
Reading through cisco documentation at: http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_52_se/configuration/guide/swspan.html The author says: "Only traffic that enters or leaves source ports or traffic that enters or leaves source VLANs can be monitored by using SPAN; *traffic routed to a source VLAN cannot be monitored*. For example, if incoming traffic is being monitored, traffic that gets routed from another VLAN to the source VLAN cannot be monitored; however, traffic that is received on the source VLAN and routed to another VLAN can be monitored." >From my understanding, after the traffic is routed to a source VLAN, it enters the VLAN and becomes part of source VLAN's traffic. In other words, it is flowing on the source VLAN, so it can be monitored by SPAN/RSPAN, am I correct ? Why the author mentioned that, since the traffic will be monitored anyway ?
