Why does the capture command when applied to the FWSM stops and does not capture traffic as soon as another capture command is applied on the interface?
A. When you configure capture ‘z’ on the same interface where capture ‘x’ is already applied, then capture ‘z’ supercedes capture ‘x’. The active capture is the last one attached to the particular interface. The only exception is when the access-list on the capture ‘x’ overlaps with the access-list of the capture ‘z’. If that is the case, then both captures continue to capture the traffic where the access-lists overlap.
