WebEthertypes The 13th and 14th octets of an Ethernet or IEEE802.3 packet (after the preamble) consist of the "Ethernet Type" or "IEEE802.3 Length" field. WebThe EtherType/Length header field apparently can indicate either a frame type or an explicit length, and I'm guessing that in the case of a frame type, it has to do some other logic to figure out how long the packet is. For example, if the EtherType field is 0x0800, that indicates an IPv4 payload, and so the receiving NIC would have to examine ...

WebThe default EtherType values in TCAM might differ across Junos OS releases and device types. Enter the show chassis fpc ether-types command to see the default and active EtherType values on one or all FPCs on the device. If you configured a custom value at a particular index, the ACTIVE column shows that value instead of the default value.

"WebJun 15, 2012 · For IPv6 packets, the EtherType field is set to 0x86DD. Thus, the determination of the protocol of the Ethernet payload occurs before the packet is passed to the appropriate protocol layer. Traffic Class The Traffic Class field indicates the IPv6 packet’s class or priority. The size of this field is 8 bits. " - Ethertype size
