USING RMON

	Table 9-19 Filter Configuration Options
Field	Description
Packet Status	The status of packets to filter: Any Packets, No Errors, Any Errors, CRC/Alignment, Packets < 64
	Bytes, Undersize (packets < 64 bytes, with no CRC/alignment errors), Packets > 1518 Bytes, Oversize
	(packets >1518 bytes, with no CRC/alignment errors), Fragments, Jabber, Other
Name	A name for this filter expression, consisting of the selected:
	Frame Type / Protocol / Upper-Layer Protocol.
Raw Data	Allows you to enter a specific data pattern to filter. Select Data and input the filter pattern, select Mask
	to indicate the relevant bits, then select Not Mask to indicate the bits that should match or not match.
	You can check for a pattern anywhere within the first 256 bytes of a frame.
	Data: The bit pattern to filter.
	Mask: The relevant bits within the data.
	Not Mask: Those bits in the mask to match (0) or not match (1).
Decoded Details	If the frame and protocol type are specified, then you can filter specific fields directly from the frame
	and protocol headers.
Load/Save As	Loads a predefined filter into the filter table, or saves the current filter as a file.

The following example shows a filter expression designed to capture any errors occurring in AppleTalk packets. While the other example shows filtering for decoded details that is designed to capture any Ethernet II packets directed to the IP address 10.1.0.23 that have the Don’t Fragment flag set.
