Enterasys C3 Configuration Guide 21-3
• RMON Packet Capture/Filter Sampling and Port Mirroring cannot be enabled on the same
interface concurrently.
• You can capture a total of 100 packets on an interface, no more and no less.
– The captured frames will be as close to sequential as the hardware will allow.
– Only one interface can be configured for capturing at a time.
– Once 100 frames have been captured by the hardware, the application will stop without
manual intervention.
• As described in the MIB, the filter is only applied after the frame is captured, thus only a
subset of the frames captured will be available for display.
• There is only one Buffer Control Entry supported.
• Due to the limitations of the hardware, the Buffer Control Entry table will have limits on a few
of its elements:
– MaxOctetsRequested can only be set to the value -1 which indicates the application will
capture as many packets as possible given its restrictions.
– CaptureSliceSize can only be set to 1518.
– The Full Action element can only be set to “lock” since the device does not support
wrapping the capture buffer.
• Due to hardware limitations, the only frame error counted is oversized frames.
• The application does not support Events. Therefore, the following elements of the Channel
Entry Table are not supported: TurnOnEventIndex, TurnOffEventIndex, EventIndex, and
EventStatus.
• There is only one Channel Entry available at a time.
– There are only three Filter Entries available, and a user can associate all three Filter Entries
with the Channel Entry.
• Configured channel, filter, and buffer information will be saved across resets, but not frames
within the capture buffer.
