28 Chapter 1 About the Passport 8672ATME Module
209195-B
The VBR service provided by the 8672 module allows a previously idle channel to
burst at a relatively high Peak Cell Rate (PCR) for a Maximum Burst Size (MBS)
of ATM cells. If the channel exhausts its MBS, the module reduces the channel’s
rate to a Sustained Cell Rate (SCR). When the channel stops transmitting, it
accumulates credit towards another burst at PCR.
The 8672 module also provides a UBR service for Transmitter channels. When a
UBR channel is opened, there is no channel rate specified. All active UBR
channels are serviced in a round-robin queue. If no rate-shaped channel is
scheduled for transmission, a single cell is sent from the channel at the head of the
UBR queue.
RFC 1483 Support
The system software on the Passport 8672ATME Module supports the
configuration of RFC 1483 LAN clients with multiprotocol encapsulation. RFC
1483 supports standards-based methods of encapsulation that enable connectivity
with third-party ATM devices. Multiprotocol encapsulation provides the
capability to set up PVCs between Centillion ATM virtual ports (VPorts) and
other clients based on LLC encapsulation. The current Centillion platform only
supports bridged variations of RFC 1483.
The Passport 8672ATME Module supports the following types of RFC 1483
ELANs:
• RFC 1483 bridged 802.3. The links can be set up within a single device or
with another switch. Multiple RFC 1483 links can be set up within one
ELAN. Both LLC and NULL encapsulation are supported.
• RFC 1483 routed IP and IPX. An RFC 1483 routed VLAN always contains
only one PVC, corresponding to a point-to-point link between routers. The
software adds and removes the MAC header, as appropriate. When
configuring an IP and IPX routed circuit, the ATM port must be the only port
assigned to the VLAN.
