WebMay 22, 2024 · The optional 802.1Q tag is inserted in front of the Ethertype field. Its four bytes increase the maximum frame size to 1522 bytes. (Two bytes are the tag marker 0x8100, four bits are used for priority codes, twelve bits are used for VLAN identification.) 802.1ad introduced double tagging ("QinQ"), so a standard frame might grow some more. – WebApr 11, 2024 · The first command output displays the switch system ID and its priority (for LACP). switch# show lacp sys-id. 32768, f04a.0206.1900 <-- Your system MAC address.

The size of the payload of non-standard jumbo frames, typically ~9000 Bytes long, falls within the range used by EtherType, and cannot be used for indicating the length of such a frame. The proposition to resolve this conflict was to substitute the special EtherType value 0x8870 when a length would otherwise be used. … See more EtherType is a two-octet field in an Ethernet frame.
