[. . . ] You cannot configure some ports on the I/O module to use the router's clock and others to use the module's clock. To change the clock source of the ports on a cOC3/STM1 I/O module from the router's clock to the module's clock or vice versa, first change the clock source of all ports to the line setting, and then to the new internal clock setting. Example
host1(config-controll)#clock source internal chassis
Use the no version to revert to the default, line. See clock source.
controller sonet
Use to select an interface on which you want to configure channelized SONET or SDH. Example
host1(config)#controller sonet 4/0
There is no no version. See controller sonet.
description
Use to assign a text description or an alias to a channelized SONET interface. You can use this command to help you identify the interface and keep track of interface connections. Use the show controllers sonet command to display the text description. Example
host1(config-controll)#description boston-sonet-interface
120
Configuration Tasks
Chapter 4: Configuring Channelized OCx/STMx Interfaces
Use the no version to remove the text description or alias. See description.
path
Use to configure paths over channelized SONET and SDH interfaces. See Interface Types and Specifiers in JUNOSe Command Reference Guide for details of the syntax. Example for a cOC3/STM1 interface
host1(config-controller)#path 2 oc1
Example for a cOC12/STM4 interface in SONET mode
host1(config-controller)#path 2 oc1 1/2
Example for a cOC12/STM4 interface in SDH mode
host1(config-controller)#path 2 stm1 2
Use the no version to delete a SONET or SDH path. See path.
path description
Use to assign a text description or an alias to a channelized SONET path. You can use this command to help you identify the interface and keep track of interface connections. Example
host1(config-controll)#path 2 description westford
Use the no version to remove the description. See path description.
path overhead c2
Use to overwrite the automatic setting for the path signal label (C2) byte. By default, the value of the C2 byte for the path is determined by the layers configured above the SONET/SDH interface and set automatically. The E Series router sets this default value in accordance with RFC 2558. (See "References" on page 117. )
CAUTION: Use this command only if you know that the automatic setting does not match the setting on the remote device. Otherwise, the remote device might send an unexpected value, and the router might lose data.

JUNOSe 11. 1. x Physical Layer Configuration Guide
Example
host1(config-controll)#path 2 overhead c2 20
Use the no version to restore the default setting, in which the value of the C2 byte is determined by the layers configured above the SONET/SDH interface. See path overhead c2.
path shutdown
Use to disable a specified path. Example
host1(config-controll)#path 2 shutdown
Use the no version to restart a disabled path. [. . . ] See tunnel-server.
Monitoring Tunnel-Service Interfaces
You can monitor tunnel-service interfaces by using the show tunnel-server command.
NOTE: The E120 and E320 Broadband Services routers output for monitor and show commands is identical to output from other E Series routers, except that the E120 and E320 router output also includes information about the adapter identifier in the interface specifier (slot/adapter/port).
show tunnel-server
Use to display status and configuration information for dedicated and shared tunnel-server ports and tunnel-service interfaces configured on the router. You can display information for a specific tunnel-server port or for all tunnel-server ports. Use the optional config keyword to display information about available and provisioned tunnel-service interfaces on each port, and to indicate whether modules that support the use of dedicated or shared tunnel-server ports are currently installed in the router. Field descriptions
Port:Appl--Identifier in slot/port or slot/adapter/port format for the module or tunneling application
slot--Number of the slot in the chassis where the module resides adapter--Number of the bay in which the I/O adapter (IOA) resides. [. . . ]
