Configurable EtherType values

You can customize the EtherType field values stored in the ternary content addressable memory (TCAM) tables. Ethernet frame headers contain an EtherType field to identify the protocol in the frame's payload so the receiving device knows how to process the traffic. The device keeps a default list of the EtherType values it can process in TCAM for fast access. With this feature, you can define custom EtherType values in place of some of the default values in the TCAM table either for a specified FPC slot or for all currently active FPCs on the switch. Some EtherType values are reserved; you can't change or reconfigure those values.
