Atm Elans, And Ethernet Vlans; Virtual Network Router; Traffic Shaping - Nortel Passport 8672ATME Using Manual

• Proprietary MIB support for configuration of RFC 1483 and ATM port
specific setup
• Manageable through the Passport CLI or Device Manager, the SNMP-based
graphical interface
• Monitored through a World Wide Web browser from anywhere on the
network.

ATM ELANs, and Ethernet VLANs

The Passport 8672ATME Module supports ATM Forum Emulated LANs
(ELANs). An ELAN extends an Ethernet VLAN, which is a broadcast domain,
over an ATM network.
In general, there is a one-to-one mapping between an ATM ELAN and an Ethernet
VLAN. An ATM ELAN never spans more than one ATM port because the
software considers each ATM port completely separate.
The Passport 8672ATME Module participates in ELANs as RFC 1483 PVCs.
Only Ethernet ELANs are supported on this module.
If you delete a VLAN, you delete 1483 ELANs associated with the VLAN.

Virtual network router

Virtual network router (VNR) refers to the routing functions between two ATM
virtual/emulated networks. You can use the Passport 8672ATME Module as an IP-
and IPX-optimized VNR.

Traffic shaping

The Passport 8672ATME Module provides per channel traffic shaping and
supports unspecified bit rate (UBR) and variable bit rate (VBR). Channels with a
specified cell rate are called rate-shaped channels.
