Some traces, such as the IP router trace or the VPN trace, produce a large number of outputs. The amount of output can become unmanageable. The trace filters allow you to sift out the information that is important to you.
A trace filter is activated by adding the parameter “@“ that induces the following filter description. In filter description uses of the following perators:
| Operator | Beschreibung |
|---|---|
| (space) | OR: The filter applies if one of the operator occurs in the trace output |
| + | AND: The filter applies if the operator occurs in the trace output |
| - | Not: The filter applies if the operator does not occur in the trace output |
| " | the output must match the search string exactly |
An operator can be entered as any string of characters, such as the name of a remote station, protocols or ports. The trace filter then processes the output according to the operator rules, much like an Internet search engine. Examples of the application of filters can be seen under .
