Configuring SONET Options for 10-Gigabit Ethernet Interfaces

The 10-Gigabit Ethernet IQ2 PIC is supported on the M120, M320, and T-series routing platforms. The PIC provides one external interface running at 10 Gbps. The interface operates in either LAN PHY or WAN PHY mode.When the external interface is running in WAN PHY mode, it uses the WIS sublayer to transport 10-Gigabit Ethernet frames in an OC192c SONET payload, and can interoperate with SONET section or line level repeaters. This creates an advantage when the interface is used for long-distance, point-to-point 10-Gigabit Ethernet links.

When the external interface is running in WAN PHY mode, you can configure specific physical SONET options. To configure SONET options, include the loopback, mpls, path-trace, and trigger statements at the [edit interfaces interface-name sonet-options] hierarchy level:



[edit interfaces]
xe-0/0/0 {



sonet-options {

loopback (local | remote);



mpls {



pop-all-labels {

required-depth number;
}


}



path-trace trace-string;



trigger {



defect ignore {

defect hold-time up milliseconds down milliseconds;
}


}


}


}

For information about using the loopback statement, see Configuring SONET/SDH Loopback Capability. For information about using the mpls statement, see Removing MPLS Labels from Incoming Packets. For information about using the path-trace statement, see Configuring the SONET/SDH Path Trace Identifier. For information about using the trigger statement, see Configuring SONET/SDH Defect Triggers to Be Ignored.
