Option -t (toggle trace)

This function is used to toggle the trace level of a running SAProuter. Trace levels 1, 2 and 3 exist. If the trace level was 1, it is now increased to 2, and if it was 2 or 3, it is decreased to 1.

You can also activate the trace for individual connections (see below).

Integration

When SAProuter is started, the trace level is selected with option -V<tracelev> .

Features

Connection Trace

You can also activate the trace for individual connections. For these connections the information is written with trace level 2.

The connection is traced using an enhanced syntax of option –t. You have the following options:

Command	Meaning
`saprouter -t "on <id>"`	`<id>` is the number of the connection. You can see this number when you display the connection information (`saprouter ‑l`). This command activates the trace for this (existing) connection. For more information, see: Option -l / -L
`saprouter -t "off <id>"`	Deactivates the trace for connection with number `<id>`.
`saprouter -t "on <IPaddress>"`	Activates the trace for all new connections coming from the IP address `<IP address>`. You use this option if the connection is not yet open and you are looking the for connection setup information.
`saprouter -t "off <IPaddress>"`	Deactivates the trace for all new connections coming from the IP address `<IP address>`.
`saprouter -t "on <subnet>"`	`<subnet>` specifies a set of IP addresses. The command activates the trace for all new connections coming from this subnetwork. More information about IP address masks: IP Address Formats
`saprouter -t "off <subnet>"`	Deactivates the trace for all new connections coming from this subnetwork.

Trace ID in the Connection Overview

Connections for which the trace is activated are marked with an asterisk in the connection overview (to display the overview enter command saprouter ‑l).

You can find the trace information in the trace file dev_rout.

Example

You activate the trace for connection number 4 by sending the command saprouter -t "on 4" to the active SAProuter.

Then you call saprouter ‑l to display the connections. You get the following output:
