Configuring SONET/SDH Interface Speed
To configure the speed of SONET/SDH interfaces in concatenated mode:
- In configuration mode, go to the [edit interfaces interface-name] hierarchy level, where the interface-name is so-fpc/pic/port.[edit]user@host# edit interfaces so-fpc/pic/port
- Configure interface speed in concatenated mode.
For example, each port of 4-port OC12 PIC can be configured to be in OC3 or OC12 speed independently when this PIC is in 4xOC12 concatenated mode.
[edit interfaces so-fpc/pic/port]user@host# set speed (oc3 | oc12 | oc48)
To configure the speed of SONET/SDH interfaces in nonconcatenated mode:
- In configuration mode, go to the [edit interfaces interface-name] hierarchy level, where the interface-name is so-fpc/pic/port.[edit]user@host# edit interfaces so-fpc/pic/port
- Configure interface speed in nonconcatenated mode.
For example, each port of 4-port OC12 PIC can be configured to be in OC3 or OC12 speed independently when this PIC is in 4xOC12 concatenated mode.
[edit interfaces so-fpc/pic/port]user@host# set speed (oc3 | oc12)
To configure the PIC to operate in channelized (multiplexed) mode:
- In configuration mode, go to the [edit chassis fpc slot-number pic pic-number] hierarchy level.[edit]user@host# [edit chassis fpc slot-number pic pic-number]
- Configure the no-concatenate option.[edit interfaces so-fpc/pic/port]user@host# set no-concatenate
 | Note: On SONET/SDH OC3/STM1 (Multi-Rate) MIC with SFP, Channelized SONET/SDH OC3/STM1 (Multi-Rate) MIC with SFP, and Channelized OC3/STM1 (Multi-Rate) Circuit Emulation MIC with SFP, you cannot set the interface speed at the [edit interfaces] hierarchy level. To enable the speed on these MICs, you need to set the port speed at the [edit chassis fpc slot-number pic pic-number port port-number] hierarchy level. For more information about using the non-concatenate statement, see the Junos OS Administration Library for Routing Devices. |
