show chassis fpc ether-types



Display the current EtherType values in ternary content addressable memory (TCAM) on a device for a specified FPC slot or for all currently active (online) FPCs on the device.

Ethernet frame headers contain an EtherType field to identify the protocol in the frame's payload so that a receiving device knows how to process incoming Layer 2 traffic. Devices store the EtherType values they can process in TCAM for fast access. You can configure custom EtherType values in place of the default values in the TCAM EtherTypes table, although some values are reserved and can't be changed or configured. For details on how to configure custom EtherType values, see the ether-type configuration statement at the [edit chassis fpc slot] hierarchy.


none Display the EtherType values in TCAM for all active (online) FPC slots.

(Optional) Display the EtherType values in TCAM for the specified FPC slot number.
