T1/E1 Configuration Tasks
Copyright © 2010, Juniper Networks, Inc.
Use to specify that the interface supports SDH.
Example
host1(config-controller)#sdh
Use the no version to revert to SONET operation on this interface.
See sdh.
Use to enable SNMP link status processing for the section and line layers of the interface.
The default is enabled.
Example
host1(config-controll)#no snmp trap link-status
Use the no version to disable SNMP link status processing.
See snmp trap link-status.
Use to set the time duration after which the router sets an alarm when it records a
defect at the line or section layer.
Change this value from the default only when you are using MPLS fast reroute over a
SONET/SDH interface.
Specify a value of 0 milliseconds if the interface does not use APS/MSP or if MPLS
should have priority over APS/MSP.
Specify a value of at least 100 milliseconds if this interface uses APS/MSP and if
APS/MSP should have priority over MPLS.
Example
host1(config-controll)#trigger delay msec 1000
Use the no version to restore the default setting, 2500 milliseconds.
See trigger delay.
Configuring Higher Layers
You must now configure the next layer on the interface: E1, T1, or T3. See "T1/E1
Configuration Tasks" on page 119 or "T3 Configuration Tasks" on page 126.
Before you configure T1 or E1 on an interface, you must configure SONET or SDH. See
"SONET/SDH Configuration Tasks" on page 115.
To configure a T1 or an E1 over SONET or SDH on a cOCx/STMx interface:
Configure a tributary for the path.
