Ingress, Egress and Observation Domain Configuration¶
The default behavior for traffic monitoring is to label the flows from each interface as its own ingress and egress. (mon1 = ingress on 1, egress on 1). By default, the observation domain is fixed at 42. However, FlowPro can be configured to label the flows as coming from any licensed ingress and egress interface, and/or from any observation domain.
For example: Users may want to label traffic monitoring so ingress is mon1 (i.e. 1) and egress is mon2 (i.e. 2).
This is done by modifying the plixer.ini
FLOWPRO> edit plixer.ini
In the editor, locate the following line:
When specified in this format, mon1 is configured for ingress of 1 and egress of 1. By modifying this setting in the following format, FlowPro will configure mon1 to have an ingress of 1 and egress of 2.
The format to use is monX:ingress:egress. Once the necessary configuration changes have been made, save the plixer.ini file. FlowPro will then restart the services with the new configuration. Note that the values for ingress and egress are limited to the maximum number of licensed interfaces.
To define a different observation domain for an interface, modify the plixer.ini file as before using the format monX:ingress:egress:observation_domain. To set the observation domain, the ingress and egress labels must also be set. To change the observation domain for mon1 to 45, while using the ingress and egress values set above, modify the setting above to read as:
Or, to use the default values for mon1 with an observation domain of 45:
