Packet Slice Size
(bytes)
The slice size in bytes; used to
limit the size of the captured
packets.
Enter a value of 64 or higher. Enter zero (0) to not perform slicing.
If you have a small session but want to capture as many packets as
possible, use a small slice size.
If the packet size is larger than the specified slice size, the packet is
sliced before it is saved in the capture session. For example, if the
packet is 1000 bytes and slice size is 200 bytes, only the first 200
bytes of the packet is stored in the capture session.
Capture Source
Data-Port or ERSPAN Choose the capture source (check one or more check boxes):
• Data-port: This accepts SPAN, RSPAN, and VACL capture. For
NME-NAM, internal, external, or both.
• ERSPAN: Locally terminated is recommended.
