The following filters are provided, but others are easily created to incorporate
several variations. Specific interface configurations and traffic generation cell
tables can be saved along with filter configurations:
• IP address filtering
• ILMI filtering
• OAM filtering
• Protocol distribution filtering
• VP.VC filtering
Display Filters and Searching
Display filtering and searching lets the user search through collected data to
find specific IP addresses, values for protocol fields, or conversations on
specific bi-directional virtual connections (by VPI-VCI). The display filters
provide the flexibility to select protocol attributes or specific protocols from
a checklist, and the power to filter on any bit, byte or characteristic, such as
protocol. For example, filtering can be preformed on OAM traffic without
having to know any of the protocol specifics.
Post-processing lets the user quickly zoom in on selected criteria, from the
traffic passing between specific devices to individual conversations.
Post-processing allows the user to:
• Search through the data by record or by time stamp
• Search for events or strings
• Filter on protocols
• Verify event-to-event timing
• View protocol errors
• Print a range of cells or the entire buffer
• Export data in CSV (comma separated variables) format
• Analyze statistics based on the buffered data
ATM Cell Generation
An ATM cell editor can build a cell table of up to 255 user defined or previously
captured cells that can then be transmitted onto the network. Editing functions
include the following:
• Add
• Edit
• Delete
• Copy
• Insert
Windows keyboard commands are also supported – Ctrl-c, Ctrl-v, Ctrl-x, etc.
Sequences of captured cells (e.g. an AAL-5 PDU) can be copied and pasted to
the cell table; the resulting cell table contents can be edited/modified (e.g. to
change the VPI-VCI or to change embedded IP addresses) and the HEC and
AAL-5 CRC recalculated, as appropriate, prior to transmission.
