IBM 9077 manual Protocol

#		the protocol
#
#	vc_multiplexed	- Use a separate PVC for each protocol
#

#LLC encapsulated bridging allows any LAN frame type to be transmitted, and

#also allows IP datagrams to be sent directly on the VC. The optional

#’restriction’ parameter can limit how IP datagrams are routed to the

#interface, and on what kind of LAN frames are transmitted on it.

#The valid values for the restrction parameter are:

#
#	broute_to_ether	- Transmit all routed IP datagrams as
#		Ethernet frames
#
#	ether_only	- Transmit all frames (routed IP datagrams and
#		all bridged LAN frames) as Ethernet frames
#
#	broute_to_fddi	- Transmit all routed IP datagrams as
#		FDDI frames
#
#	fddi_only	- Transmit all frames (routed IP datagrams and
#		all bridged LAN frames) as FDDI frames
#

#Note that unless a restriction or an ARP service is specified, an

#LLC-encapsulated bridging interface will only be able to route to the host at

#the other end of the ATM PVC.

#

#PVC’s

#Lines beginning with the keyword "PVC" define

#Permanent virtual circuits.

#

#The format of a PVC definition is:

#PVC ifname VPI/VCI \

#proto=iprawvcipnllcisisllc[,bridging]vcmux_bridge,bprovc_atmp \

#[input_aal=35NONE] [traffic_shape=shape] \

#[dest_if=logical_if [dest_vc=VPI/VCI]]

#

#The first three parameters (ifname, VPI/VCI, and proto) are mandatory.

#’ifname’ specifies the GigaRouter ATM logical interface in the usual

#format (e.g., ga030, ga0e80).

#

#’VPI/VCI’ specifies the (decimal) Virtual Path Identifier and

#Virtual Circuit Identifier of the PVC, separated by a slash (/).

#’proto’ specifies the protocol to be supported on this PVC. Legal

#values are:

#	’ip’	Internet Protocol (with LLC/SNAP headers)
#	’raw’	raw adaptation layer (AAL-5 or AAL-3/4) packets
#	’isis’	IS-IS packets
#	’llc’	any LLC-encapsulated protocol supported by the GRF
