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 | Description |
|---|---|
| (space) | OR: The filter applies if one of the operators 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.
