IBM 9077 SP Switch Router: Get Connected to the SP Switch

# 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.

#Interface ga090 service=arp0 traffic_shape=high_speed_high_quality

#Interface ga0980 service=net20 traffic_shape=low_speed_high_quality

#Interface ga0a0 service=arp0 traffic_shape=high_speed_high_quality

#Interface ga0a80 service=net20 traffic_shape=low_speed_high_quality

#Interface ga091 traffic_shape=high_speed_high_quality \

# bridge_method=llc_encapsulated,broute_to_ether

#

# PVC’s

#

# Lines beginning with the keyword "PVC" define

# Permanent virtual circuits.

#

# The format of a PVC definition is:

#

# PVC ifname VPI/VCI \

# proto=ip|raw|vc|ipnllc|isis|llc[,bridging]|vcmux_bridge,bpro|vc_atmp \

# [input_aal=3|5|NONE] [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
