JUNOS 10.1 Network Interfaces Configuration Guide
Configuring the ATM-to-Ethernet Interworking Inner VLAN Identifier Range
Configure the Ethernet logical interface inner VLAN ID range by including the
inner-vlan-id-range
ID at the
VLAN IDs 0 and 4095 are reserved by IEEE 801.1q and must not be used for the
inner or outer VLAN ID.
VCIs 0 through 31 are reserved for ATM management purposes by convention.
Therefore inner VLAN IDs 1 through 31 should not be used.
VLAN ID 1 might be used by Ethernet switches for certain bridge management
services, so using VLAN ID 1 for the inner or outer VLAN ID is discouraged.
Configuring the ATM-to-Ethernet Interworking Physical Interface VPI
Configure the ATM physical interface VPI by including the
interfaces interface-name atm-options]
VPI 0 is reserved, and must not be used.
ATM F4/F5 OAM is not supported for VPIs used in ATM-to-Ethernet interworking
cross-connects. Any F4/F5 OAM cells received are discarded.
Only one logical interface may be declared per virtual path specified in the
statement hierarchy.
It is not necessary to dedicate all the VPIs of an ATM2 interface for ATM-to-Ethernet
interworking cross-connects.
Configuring the ATM-to-Ethernet Interworking ATM Logical Interface
Configure the ATM logical interface by including the
specifying the encapsulation type
unit logical-unit-number]
An ATM logical interface configured with the encapsulation type
supports the

features are not supported by logical interfaces configured with the encapsulation
