Configuring Channelized IQ and IQE SONET/SDH Loop Timing
The loop-timing and no-loop-timing statements apply only to E1 and T1 interfaces you configure on channelized IQ and IQE PICs. If you attempt to include these statements on any other interface type, they are ignored.
To configure SONET/SDH or DS3-level clocking:
- In configuration mode, go to the [edit interfaces interface-name sonet-options] hierarchy level or to the [edit interfaces ct3-fpc/pic/port t3-options].[edit]user@host# edit interfaces interface-name sonet-options[edit]user@host# edit interfaces ct3-fpc/pic/port t3-options
- Configure SONET/SDH or DS3-level clocking. By default,
internal clocking (line timing) is used on channelized IQ and IQE
interfaces. [edit interfaces interface-name sonet-options]user@host# set loop-timing[edit interfaces ct3-fpc/pic/port t3-options]user@host# set loop-timing
To configure the default line timing explicitly:
- In configuration mode, go to the [edit interfaces interface-name sonet-options] hierarchy level or to the [edit interfaces ct3-fpc/pic/port t3-options].[edit]user@host# edit interfaces interface-name sonet-options[edit]user@host# edit interfaces ct3-fpc/pic/port t3-options
- Configure the default line timing explicitly.[edit interfaces interface-name sonet-options]user@host# set no-loop-timing[edit interfaces ct3-fpc/pic/port t3-options]user@host# set no-loop-timing
To configure clocking for all channelized IQ and IQE PICs which is supported on all channels.
- In configuration mode, go to the [edit interfaces type-fpc/pic/port] hierarchy level.[edit]user@host# edit interfaces type-fpc/pic/port
- Configure the clocking option. If you do not
include the clocking statement, the individual interfaces
use internal clocking by default.[edit interfaces type-fpc/pic/port]user@host# set clocking
