Configuring the JUNOS Software to Enable SONET/SDH Framing for SONET/SDH PICs

In JUNOS Release 8.4 and later, the family of next-generation SONET Phase I PICs includes Type 2 and Type 1 PICs. Each PIC type has three varieties.

Type1 PICs include:

  • 4-port OC3
  • 2-port OC3
  • 1-port OC12

Type 2 PICs include:

  • 1-port OC48
  • 4-port OC12
  • 4-port OC3

The support both type 1 and type 2 FPC interfaces. Hot-pluggable SFPs are used as optical transponders. The PICs provide unprecedented flexibility by allowing the user to configure a variety of modes on them through the configuration of concatenation/nonconcatenation and speed.

The 4-port OC48 PIC with SFP installed, the next-generation SONET/SDH PICs with SFP, and the 4-port OC192 PIC on M Series and T Series routers, support SONET or SDH framing on a per-port basis. This functionality allows you to mix SONET and SDH modes on interfaces on a single PIC.

For information about configuring SONET/SDH framing, see Configuring the JUNOS Software to Enable SONET/SDH Framing for SONET/SDH PICs.

For information about configuring port speed for concatenate mode on a next-generation PIC, see the JUNOS Hardware Network Operations Guide.

By default, SONET/SDH PICs use SONET framing. For a discussion of the differences between the two standards, see the JUNOS Network Interfaces Configuration Guide.

To configure a PIC to use SDH framing, include the framing statement at the [edit chassis fpc slot-number pic pic-number] hierarchy level, specifying the sdh option:

[edit chassis]user@host# set fpc slot-number pic pic-number framing sdh[edit chassis]user@host# showfpc slot-number {pic pic-number {framing sdh; }}

On a TX Matrix or TX Matrix Plus router, include the framing statement at the [edit chassis lcc number fpc slot-number pic pic-number] hierarchy level, specifying the sdh option:

[edit chassis lcc number]user@host# set fpc slot-number pic pic-number framing sdh[edit chassis lcc number]user@host# showfpc slot-number {pic pic-number {framing sdh; }}

To explicitly configure a PIC to use SONET framing, include the framing statement at the [edit chassis fpc slot-number pic pic-number] hierarchy level, specifying the sonet option:

[edit chassis]user@host# set fpc slot-number pic pic-number framing sonet[edit chassis]user@host# showfpc slot-number {pic pic-number {framing sonet;}}

On a TX Matrix or TX Matrix Plus router, include the framing statement at the [edit chassis lcc number fpc slot-number pic pic-number] hierarchy level, specifying the sonet option:

user@host# set fpc slot-number pic pic-number framing sonet[edit chassis lcc number]user@host# showfpc slot-number {pic pic-number {framing sonet;}}
