Resnet ona Guide


Open Network Administrator (ona) is a network management tool developed and maintained by the IST Network Services group. ona is used for campus wide network switch and router management, including resnet. This guide covers the ona functions that are provided for staff and RCC's in UW's Housing department and the Colleges.

If you have suggestions for improvements to either ona, or this guide, or if you would like to arrange to receive a tutorial on ona, please contact BruceCampbell

ona has features beyond those covered in this guide. The full ona manual is available here.

Getting Started

If you do not have access to ona, and you are either an RCC, or a staff member involved in resnet management, submit a request through IST's Request System for ona access, and also request to be added to the resnet mail list.

Once you have been granted ona access, visit the ona web page at and
click on the Open Network Administrator (cn-ona) link. When prompted, enter your uwuserid and password.


Screens and Navigation

Main Screen

After successful login, you will see the Main screen. You can return to the Main screen from most other ona screens, by clicking the Main button. The Main screen shows the list of network switches in your area, and some information about each. If a switch has a red background, it means the switch is down, and needs to be fixed.


Switch Screen

Clicking on a switch name, like rn-sw-rena-1-1-a, from the Main screen opens a switch screen. The switch screen shows the list of ports on the switch, usually numbered 1 to 48 (in the Edit column).


Port Screen

Clicking on a port number, like 2 (in the Edit column), from a Switch screen, opens a port screen. You can return the the switch screen by clicking on the button with the switch name on it. From the port screen, you can disable/enable a port (the State field), set a Comment, clear the MAC address or intrusion flag, and view the change history, secure mac addresses, and intrusion log.


Search Screen

The Search button is available on the Main, switch, or port screen. The Search button opens the Search screen. There are 4 types of searches supported:

Search by IP name, IP address or MAC address will attempt to find the current port on which the IP or MAC is located. For a historical search, select the Dynamic IP trace checkbox. Dynamic IP trace only works with IP names or addresses, it does not support MAC addresses or rooms.

How To's

Finding the port for a given room

Use the Search screen or Buildings screen.

From the Buildings screen, click on the building in the left column, and then click on the room.


Use the Search screen. Enter the room number, e.g. V1 3101 and click Search. You do not need to enter the letter prefix or suffix for a room, or the full building code. The search will find all matching rooms.

The list of buildings as shown on the Buildings screen is below. If you can't remember the full code, just enter it partially, e.g. "REN" or "STP", or visit the Buildings screen for the list.

Finding the port for a given IP name or IP address (or MAC address)

Use the Search screen. Enter the IP name, IP address, or MAC address, and click Search. The result is the most recent port for the supplied name/address.

If you need to determine where a given IP name/address was at a given date/time in the past, check the Dynamic IP trace checkbox. The result is the complete history of which MAC addresses have used the IP name/address, and which ports have been used by these MAC addresses. This is useful if you are investigating a report of misuse at a given date/time, by a given IP name/address.

Enabling/disabling a port

Once you have navigated to the port screen for the port desired, either by searching by IP name/address, by room, or by navigating from a switch screen, you may disable or enable the port by changing the State field, and clicking either of the Change and save settings buttons. Your change will be made, and displayed in the Port change history.

If you are disabling a port because of suspected misuse or virus infection, it is recommended to set the Comment field to something informative, so that other staff members are aware of the issue when the user comes to the help desk.

Important do not disable ports serving VoIP phones or wireless access points. These can be identified by a 2 in the Maxmacs field. A mechanism to allow disabling the computer without disabling the phone/AP will be provided soon.

Clearing the MAC address on a port

Resnet ports automatically clear themselves anytime the computer is disconnected, turned off, or left inactive for 5 minutes.
