This option can only be applied to Ethernet switching module ports. It is set to the following:

No translation is performed on outbound Ethernet frames where 
the inbound interface was Ethernet.

IP frames are transmitted as Ethernet II frames.

All IPX frames are transmitted as Ethernet II frames. The only 
exception is when LLC passthrough mode is enabled, then the 
IEEE 802.2 (LLC) frames are forwarded as is.

No translation is performed on Appletalk frames, and we 
currently support only Appletalk Phase II (SNAP format).

Other than IP and IPX, all other Ethernet II or SNAP frames are 
transmitted as Ethernet II frames.

Other IEEE 802.3 with LLC are not translated.

IPX frames from FDDI, Token Ring, and Ethernet SNAP frames 
are translated to Ethertype. 

All other SNAP frames from FDDI, Token Ring, and Ethernet 
SNAP are translated to Ethertype. However, Appletalk ARP SNAP 
frames from Token Ring and FDDI are left as SNAP; Banyan 
Vines frames from FDDI are translated to Ethertype.

All other 802.2 frames from FDDI, Token Ring, and Ethernet are 
left as is. The exception are Banyan Vine frames from Token 
Ring, which are translated to Ethertype.

All Ethernet Ethertype frames are not translated.
