1. Log in to the switch connected to the IPC in local Console port mode or network (for example, STelnet) mode.
2. Run the dis logbuffer command and press Space to print the complete log information.
3. Run the dis trapbuffer command and press Space to print the complete log information.
4. Run the dis diagnostic-information command.
5. Run the dis interface command to collect switch port information.
6. Run the dis mac-address command to collect the switch MAC table.
7. If the IPC uses PoE, run the following commands in sequence to collect PoE-related information:
   • dis poe information
   • dis poe-power
   • dis poe power
   • dis poe power-state
   • dis poe power-state interface gig 0/0/4
     NOTE:

     In the preceding command, 0/0/4 indicates the number of the port on the switch that connects to the IPC. You can set it based on the site requirements.

8. Export the session log of the login tool to a local disk.

   For example, if you use the SecureCRT tool to log in to the switch, you can choose File > Log Session to export and save the session log.

Log in to the IPC web page, choose Settings > System Configuration > Device Maintenance > One-Click Collection, and download the IPC fault information to a local disk, as shown in Figure 1.
