I have configured SPAN on 3750 switch and couldn't see any L2 protocol updates on destination port.is it normal behaviour
and I am aware on this
# A destination port does not participate in spanning tree while the SPAN session is active.
# When it is a destination port, it does not participate in any of the Layer 2 protocols (STP, VTP, CDP, DTP, PagP).
but question is I should see L2 protocols info of source interfaces i am trying to monitor ?
