Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter6 Card and Service Configuration
The Processor Switching Module
b. For an internal clock source:
popeye1r.1.8.PXM.a > cnfclksrc 7.1 P
Step 2 Check the configuration by executing dspclksrc.
If you have specified an external clock source, use the CiscoView application or the CLI command
cnfextclk to select the T1 or E1 line and the impedance of the line. The syntax for cnfextclk is:
cnfextclk <ClockType> <Impedance>
ClockType can be 1 for T1 or 2 for E1. Impedance can be 1 for 75 ohms, 2 for 100 ohms, or 3 for
120 ohms.
Step 3 Specify the Stratum level of the clock source (Stratum 3 or Stratum 4).
cnfclklevel <level>
The level can be 3 for Stratum 3 clocking, or 4 for Stratum 4 clocking.
Note For external clocking sources, Stratum 3 is supported by the PXM-UI-S3 card; Stratum 4
sources are supported by the PXM1-UI back card. Either Stratum 3 or Stratum 4 can be used
as internal clocking sources.
Configuring PXM1 Card-Level Parameters, Lines, and Ports
This section describes how to configure card-level features, activate a physical line, and configure
logical elements such as a port.
Refer to the section titled “Sequence of Configuration Tasks, page 6-2” for background information on
these types of tasks.
Step 1 Optionally, you can modify the resource partitioning for the whole card by executing cnfcdrscprtn. You
can view resource partitioning through dspcdrscprtn.
cnfcdrscprtn <number_PAR_conns> <number_PNNI_conns> <number_TAG_conns>
• number_PAR_conns is the number of connections in the range 0–32767 for PAR.
• number_PNNI_conns is the number in the range 0–32767 available to PNNI.
• number_TAG_conns is the number of connections in the range 0–32767 for MPLS.
For example, you could reserve 10,000 connections for each controller on a PXM1 with:
cnfcdrscprtn 10000 10000 10000
Step 2 Activate a line by executing addln:
addln -ds3 <slot.line> | -e3 <slot.line> | -sonet <slot.line>
• -ds3 indicates a T3 line parameter follows.
• -e3 indicates an E3 line parameter follows.
• -sonet indicates an OC-3 or OC-12 line parameter follows.
• slot is the slot number for the PXM1. If the switch has a redundant pair of SRMs, execute addln
again for those slots.
