Setting Up SRM Lines
If you are configuring a Cisco MGX 8850 (PXM1E/PXM45) switch, replace X with 15 for an SRME in
the upper bay, or 31 for an SRME in the lower bay. If you are configuring a Cisco MGX 8830 switch,
replace X with 7. SRME provides one line, so the line number is always one as shown in the following
example:
PXM1E_SJ.8.PXM.a > dspln -sonet 31.1

Step 3 To configure a SONET or SDH line, enter the cnfln command as follows:
mgx8830b.1.PXM.a > cnfln -sonet <X.1> -slt <LineType> -clk <clockSource>
-sfs <FrameScramble> -rdiv <RDI-V Type> -rdip <RDI-P Type> -tt <Tributary Type> -tm
<TributaryMappingType> -tf <TributaryFramingType> -st <SignallingTranportMode> -tg
<TributaryGroupingType>
Remember that you cannot configure a line until you have brought it up as described in the previous
section,

Description
Replace X with 15 if you are configuring an SRM in the upper
bay, or replace it with 31 if you are configuring an SRM in
the lower bay.
The number 1 represents the one and only line on an SRME
card.
Optical line type. Replace < LineType> with 1, to specify
SONET, or replace < LineType> with 2 to specify SDH.
The -clk option selects the primary source timing for
transmitting messages over the line. Replace <clockSource>
with 1 to use the clock signal received over this line from a
remote node, or specify 2 to use the local timing defined for
the local switch.
On SRME/B cards, when the selected primary source
Note
timing is not operating properly, the SRME/B will
use the other timing option. For example, if you select
option 1 as the primary source, option 2 will be the
secondary source and will be used when the option 1
timing fails.
For information on defining the clock source for the local
switch, see the
Network Using
Operating Procedures."
