Monitoring Chassis Information



This topic applies only to the J-Web Application package.

Use the monitoring functionality to view chassis properties such as general switch information, temperature and fan status, and resource information for the EX Series switch.


To view chassis properties in the J-Web interface, select Monitor > System View > Chassis Information. For an EX8200 Virtual Chassis configuration, select the Virtual Chassis member from the list.

To view chassis properties in the CLI, enter the following commands:

  • show chassis environment

  • show chassis fpc

  • show chassis hardware


Table 1 gives information about the key output fields for chassis information.


For an EX2200, EX2200-C, EX3200, or EX4500 switch or an EX4200 or EX4550 standalone switch, the FPC slot number refers to the switch itself and is always 0. In a Virtual Chassis configuration, the FPC slot number refers to the member ID.
