The Ethertype Option
This option can only be applied to Ethernet switching module ports. It is set to the following:
Ethernet Media - Ethernet II Mode
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.
ATM LANE - Ethernet II Mode
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.
