Hierarchy Level

Release Information

Statement introduced in Junos OS Release 12.2 for ACX Series Universal Access Routers.

Description

Specify the physical link-layer encapsulation type.

Options

cesopsn

—

Use Circuit Emulation Service over Packet-Switched Network (CESoPSN) encapsulation on DS0 (ds-x/y/z:n) interfaces to encapsulate TDM signals into CESoPSN packets, and in the reverse direction, decapsulating CESoPSN packets back into TDM signals.

ethernet-ccc

—

Use Ethernet CCC encapsulation on Ethernet interfaces that must accept packets carrying standard Tag Protocol ID (TPID) values.

flexible-ethernet-services

—

Use flexible Ethernet services encapsulation when you want to configure multiple per-unit Ethernet encapsulations. Aggregated Ethernet bundles can use this encapsulation type. If you configure flexible Ethernet services encapsulation on the physical interface, VLAN IDs from 1 through 511 are no longer reserved for normal VLANs.

ima

—

Use Inverse Multiplexing ATM (IMA) encapsulation on E1 and T1 interfaces that are members of an IMA group.

satop

—

Use Structure-Agnostic TDM over Packet (SAToP) encapsulation on E1 and T1 interfaces so that the Interworking Function (IWF) can segment and encapsulate TDM signals into SAToP packets, and in the reverse direction, decapsulate the SAToP packets and reconstitute them into TDM signals.
