Please fill out this form in order to request the activation of a networking connection. Information we will ask you to provide includes the following:

  • Building
  • Room Number
  • Port Information
  • Network Name

 

Switch/Port Information

To speed up your request, please utilize CDP to provide the switch and port information:

Overview:
CDPR is used to get the switch information that a specific port is connected to. We do this if we need to move a port to a specific VLAN network. It listens for an update packet from the switch which broadcasts every 60 seconds. Once cdpr gets the packet, it dumps the information into a .csv file for viewing in Excel or other programs.

Instructions:
To install:

  • WinPcap is longer being developed, and all versions are vulnerable to DLL hijacking. Please download and install Npcap instead:
  • Download cdpr_v2 from
  • Extract the contents of the .zip file

To use:

  • Navigate to the cdpr_v2 directory 
    • Example: c:\cdpr_v2
  • Run cdpr.bat
  • It will list all the network adapters available on the computer. Enter the interface you want to use. This will most likely be the Ethernet adapter
  • Wait for the switch information to be broadcasted
  • Enter a Tag. This is the Port and Plate number you are connected, to along with building and room number
  • Press any key to continue
  • Open log.csv (also in the cdpr_v2 directory) to make sure it got the information and tagged it correctly
    • Example: c:\cdpr_v2\log.csv

Notes/Known Issues:
If you are going to be using the same adapter every time, you can edit the batch file to auto select a specific adapter. This can be done by using the –d flag and inputting the device number.
