Q:  Can I set up my own traffic filter?

A: Yes, in Capsa, setting up a set of rules can help you filter the traffic you are interested in. The filters help user to speed up analyzing and displaying packets,  enabling you to focus on what you are really interested in. Capsa has two kinds of filters: global filters and project filters. Global filters are some commonly used protocols filters, which can be applied to the current project. Project filters are only applied to the current project.

Q: Can Capsa monitor the traffic utilization in the network?

A: Yes,  Capsa provides users with detailed network statistics information of the overall network or  each network segment, traffic utilization status, top talkers,  congestion, MAC/IP address or protocol,  bitrate,  and TCP transaction statistic etc..

Q: Our LAN is connected with a hub, but I can only detect my own traffic.

A: Generally, if a NIC supports promiscuous mode it can work well with Capsa, a possible reason is your hub actually acts as a switch though labeled as a hub (e.g. Linksys hubs). Another possible reason is you are using a multi-speed hub, in which case you can't see the traffic from the stations operating at the speed that is different from your NIC's speed (e.g. if you have a 10 Mbit NIC, you can't see the traffic generated by 100 Mbit NICs).

Q: How to configure port mirroring?

A: Please read your switch's manual or visit its website to learn how to setup port mirroring. Or you may ask their technicians for help.

Q: Does Colasoft Capsa enable me as a network administrator to easily see who is listening to the radio and downloading music online?

A: Yes. The standard ports for media protocols are: RTSP - port 554 PNM - port 7070 (also known as PNA port) MMS - port 1755 By setting port filters in the "Project Settings - Filter" dialog box you can easily find out who is visiting media resources; to monitor the downloads of media files (e.g. .rm), you can set a URL filter for HTTP analysis in the "Project Settings - Advanced Analyzer" dialog box.

Q: Why don't I see the Dashboard tab sometimes?

A: The Dashboard is visible only when you select the root node in the Node Explorer. That's because the Dashboard is global, which doesn't belong to any specific node in the Node Explorer. When a node selected in the Node Explorer, only the tabs relating to the selected is visible.
