For Ethernet switching module ports the factory default is set to the following:

For FDDI switching module ports the factory default is set to the following:

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

IP frames of any encapsulation are transmitted as Ethernet II 
frames.

IPX frames are transmitted as IEEE 802.3 Proprietary as the 
default setting. 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).

Banyan Vines frames are transmitted as Ethernet II frames.

Other than IP and IPX, all other Ethernet II and SNAP encapsu-
lated protocols are sent as Ethernet II frames.

All other IEEE 802.3 with LLC encapsulated protocols are not 
translated.

IP of any encapsulation is encapsulated SNAP

IPX encapsulations are encapsulated SNAP except for IEEE 802.2 
which is forwarded as is.

Banyan Vines of any type are transmitted as SNAP.

All other Ethertype and SNAP encapsulated protocols are sent as 
for IP.

All other LLC encapsulated protocols are forwarded as is.
